Aspects Med. 50: 56–87. doi:10.1016/j.mam.2016.04.006. PMID 27106402. In conclusion, HMB treatment clearly appears to be a safe potent strategy against sarcopenia, and more generally against muscle wasting, because HMB improves muscle mass, muscle strength, and physical performance. It seems that HMB is able to act on three of the four major mechanisms involved in muscle deconditioning (protein turnover, apoptosis, and the regenerative process), whereas it is hypothesized to strongly affect the fourth (mitochondrial dynamics and functions). Moreover, HMB is cheap (~30– 50 US dollars per month at 3 g per day) and may prevent osteopenia (Bruckbauer and Zemel, 2013; Tatara, 2009; Tatara et al., 2007, 2008, 2012) and decrease cardiovascular risks (Nissen et al., 2000). For all these reasons, HMB should be routinely used in muscle-wasting conditions especially in aged people. ... 3 g of CaHMB taken three times a day (1 g each time) is the optimal posology, which allows for continual bioavailability of HMB in the body (Wilson et al., 2013).
If you'’re looking to add muscle mass to your frame, hitting the weights hard is a given. Quality time in the gym begins a cascade of changes that will stimulate your muscles to grow bigger in response to the challenges you throw their way. It'’s tempting to think that'’s all it takes to add muscle to your body. After all, you can actually feel your biceps growing after an intense set of curls.
Creatine is known to occur in highly concetrated levels in chicken photoreceptors, relative to other parts of the eye (10-15mM[466]) alongside high levels of creatine kinase.[466] The creatine transporter in human eyes also seems to be concentrated in the photoreceptors,[468] which are known to be susceptible to hypoxic cellular death[471][472] which, for humans, usually means retinal detachment.[473]
The effects of testosterone in humans and other vertebrates occur by way of multiple mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors.[113][114] Androgens such as testosterone have also been found to bind to and activate membrane androgen receptors.[115][116][117]
For several years, research studies have shown that adolescents concerned with both athletics and appearance are taking performance-enhancing supplements. A study by the American Academy of Pediatrics of middle-school and high-school students ages 10 to 18 years found creatine use in all grades 6 through 12. About 5.6% of the study participants and 44% of high-school senior athletes admitted taking creatine.

Firstly, let’s establish where your glutes are and what they actually refer to! Your ‘glutes’ — or your gluteal muscles, as they are more formally known — refer to the muscles in your butt. Specifically, there are three major muscles in this area: your gluteus maximus (the main, large muscle that shapes your backside), your gluteus medius and your gluteus minimus (two smaller muscles that assist the gluteus maximus in moving your body).
Rheumatoid arthritis. Early research shows that taking creatine by mouth daily increases lean muscle mass and may improve muscle strength, but does not improve physical functioning in adults with rheumatoid arthritis. In children, taking a specific supplement containing creatine and fatty acids twice daily for 30 days might reduce pain and swelling. But the effects of creatine alone are not clear.
Han:SPRD‐cy rats (human polycystic kidney disease model[514][515]) have pre-existing renal damage, which is accelerated upon ingestion of creatine supplementation at 0.3% of the diet for five days and 0.03-0.05% for the next 35 days (equivalent to human loading and maintenance).[516] During this particular disease state, renal water content and size progressively increases.[514][515] Since creatine supplementation furthered the increase by an additional 2.1%, it was thought that this property of creatine explained the 23% increased cyst scores seen relative to control.[516]
However, protein isn’t everything. Contrary to popular belief, carbohydrates and calories from fats are also important. To gain muscle, people who are slender or scrawny need to create a calorie surplus in order to bulk up. That means you need proteins and plenty of healthy carbs, vegetables and even some fats (think healthy fats like nuts, avocado, olive oil, etc.). Carbohydrates play a key role in building muscle. This macronutrient has gotten a bad rap for making people fat. However, if you work out properly, eating plenty of carbs is in your best interest. After training, it’s ideal to ingest some carbs in combination with protein to help replenish your muscles’ glycogen stores.

A typical creatine supplementation protocol of either a loading phase of 20 to 25 g CM/d or 0.3 g CM/kg/d split into 4 to 5 daily intakes of 5 g each have been recommended to quickly saturate creatine stores in the skeletal muscle. However a more moderate protocol where several smaller doses of creatine are ingested along the day (20 intakes of 1 g every 30 min) could be a better approach to get a maximal saturation of the intramuscular creatine store. In order to keep the maximal saturation of body creatine, the loading phase must be followed by a maintenance period of 3-5 g CM/d or 0.03 g CM/kg/d. These strategies appear to be the most efficient way of saturating the muscles and benefitting from CM supplementation. However more recent research has shown CM supplementation at doses of 0.1 g/kg body weight combined with resistance training improves training adaptations at a cellular and sub-cellular level. Creatine retention by the body from supplementation appears to be promoted by about 25% from the simultaneous ingestion of carbohydrate and/or protein mediated through an increase in insulin secretion. This combination would produce a faster saturation rate but has not been shown to have a greater effect on performance.
Men appear to have higher active creatine-kinase systems, and racial differences favor black people over hispanic people over white people in terms of the activity of the creatine-kinase system. This system is more variable in men, independent of supplementation. Exercise may increase the activity of the creatine-kinase system independent of supplementation.
Aging (senescence, specifically) is characterized by deterioration in many biological processes, including energy supply and regulation of oxidative stress. Therefore, there are good reasons to believe that creatine may improve numerous variables that often worsen with age, including physical function and quality of life in people with osteoarthritis, blood lipids, blood sugar regulation in type 2 diabetes, and cognition. Speaking of which…
Testosterone replacement therapy is currently only FDA approved for men who have been diagnosed with hypogonadism, but it’s also prescribed off-label for older men who take it in hopes that it will improve their libido. The use of testosterone therapy is increasingly common in the United States, with more than 2 million men receiving the therapy. Not every man benefits from taking testosterone supplements. Testosterone is available in different forms, including topicals such as gels, creams, and patches; injections; and pellets that are surgically placed directly beneath the skin. (7)
Injections of creatine are known to be neuroprotective against low oxygen levels (hypoxia) even to neonatal rats.[532] This is thought to be associated with the increased collective pool of phosphocreatine and creatine.[236] Since oral ingestion of creatine by the mother increases brain concentrations of creatine by 3.6% in the fetus prior to birth,[531] it is thought to be protective in the fetuses subject to hypoxic (low oxygen) stressors, such as a caesarean section.

In complex training, weight training is typically combined with plyometric exercises in an alternating sequence. Ideally, the weight lifting exercise and the plyometric exercise should move through similar ranges of movement i.e. a back squat at 85-95% 1RM followed by a vertical jump. An advantage of this form of training is that it allows the intense activation of the nervous system and increased muscle fibre recruitment from the weight lifting exercise to be utilized in the subsequent plyometric exercise; thereby improving the power with which it can be performed. Over a period of training, this may enhance the athlete's ability to apply power.[39] The plyometric exercise may be replaced with a sports specific action. The intention being to utilize the neural and muscular activation from the heavy lift in the sports specific action, in order to be able to perform it more powerfully. Over a period of training this may enhance the athlete's ability to perform that sports specific action more powerfully, without a precursory heavy lift being required.


As scientific research progressed, it became apparent that the best types of protein came from milk and eggs. That led to the next great revolution in sports nutrition, namely the engineered food, pioneered by Scott Connelly, M.D., a critical care specialist from Northern California who teamed with a young entrepreneur named Bill Phillips from Golden, Colorado.
“Don't get set into one form, adapt it and build your own, and let it grow. Be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot. Now water can flow or it can crash. Be water, my friend.” Bruce Lee
Besides the high-quality protein content of casein/whey, the newer formulations have little or no lactose (i.e., milk sugar), which some people have negative reactions to. The native milk proteins also provide a host of smaller proteins called peptides, many of which, such as lactoferrin, have vital health benefits. The rich cysteine content of whey acts as a precursor of glutathione, a primary endogenous antioxidant and liver detoxifier in the body.
In males, testosterone is synthesized primarily in Leydig cells. The number of Leydig cells in turn is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, the amount of testosterone produced by existing Leydig cells is under the control of LH, which regulates the expression of 17β-hydroxysteroid dehydrogenase.[132]
When it comes to training, I prefer to stick with the basics. People think they need 10 different exercises to fashion a fine pair of cheeks, but that's not what it takes. When it comes to toning your glutes, you only need two things: drive and dedication—and I mean real dedication. You must train your glutes hard and diligently to get a great response. If you stop every time it gets difficult or whenever it burns, you're not going to get anywhere.

You don't need to design a fresh plan every three weeks. Scaling up weight and modifying reps are obviously both important for progression, but playing with different set styles will shock your body and keep things interesting. Remember, bodybuilding isn't meant to feel like a chore. Below, we explain eight different types of sets to help you build muscle more efficiently during bodybuilding training.


Sound complicated? Fortunately, there's an easy rule of thumb for increasing your training volume: For each exercise, perform three to six sets of six to 12 reps, resting for 30 to 90 seconds between each set, she says. The weight used should be enough that you can get out your last reps with proper form but wouldn't be able to perform any additional reps.

Without supplementation, approximately 14.6mmol (2g) of creatinine, creatine’s urinary metabolite, is lost on a daily basis in a standard 70kg male ages 20-39. The value is slightly lower in females and the elderly due to a presence of less muscle mass.[35] This amount is considered necessary to obtain in either food or supplemental form to avoid creatine deficiency. Requirements may be increased in people with higher than normal lean mass.[35][198] Creatine excretion rates on a daily basis are correlated with muscle mass, and the value of 2g a day is derived from the aforementioned male population with about 120g creatine storage capacity.[35] Specifically, the rate of daily creatine losses is about 1.6%[199]-1.7%,[25] and mean losses for women are approximately 80% that of men due to less average lean mass.[35] For weight-matched elderly men (70kg, 70-79 years of age) the rate of loss of 7.8mmol/day,[49] or about half (53%) that of younger men.


The majority of creatine in the human body is in two forms, either the phosphorylated form making up 60% of the stores or in the free form which makes up 40% of the stores. The average 70 kg young male has a creatine pool of around 120-140 g which varies between individuals [10,11] depending on the skeletal muscle fiber type [1] and quantity of muscle mass [11]. The endogenous production and dietary intake matches the rate of creatinine production from the degradation of phosphocreatine and creatine at 2.6% and 1.1%/d respectively. In general, oral creatine supplementation leads to an increase of creatine levels within the body. Creatine can be cleared from the blood by saturation into various organs and cells or by renal filtration [1].
Unfortunately, it’s hard to significantly increase levels through food alone. That’s where supplementation comes in. For instance, in one 12-week study of resistance-trained individuals, taking HMB in tandem with a high-intensity lifting routine significantly improved muscle strength and size compared to lifting alone. Plus, in the off-chance that you push yourself too hard, HMB helps prevent the effects of overtraining—including muscle loss.
Expert tip: To make it harder, inch yourself close to a wall so your trunk is about a foot away. Bring what would be your “planted” leg on the wall, foot flat against the surface. From here, raise your “non-working leg” up into the air, keeping your knee bent. As you raise up into the glute bridge, you’ll drive your heel against the wall, raising your hips. You can also use a bench. And like the standard bridge, you can up the ante by adding weight. 

Recommended Dose: 3-6 grams before or during exercise. A ratio of two parts leucine to one part each of isoleucine and valine appears to be most beneficial. As Krissy Kendall, PhD, explains in "The Top 7 Supplements to Boost Endurance Performance," BCAAs can be just as effective for endurance athletes like runners, rowers, and cyclists as they can be for lifters and bodybuilders.


Creatine levels in the blood tend to return to baseline (after a loading with or without the maintenance phase) after 28 days without creatine supplementation.[152][200][201] This number may vary slightly from one individual to another, and for some may exceed 30 days.[202] Assuming an elimination rate of creatinine (creatine’s metabolite) at 14.6mmol per day,[35][201] six weeks of cessation is approaching the upper limit for serum creatine to completely return to baseline.
One of the studies noting a reduction in fatigue in healthy subjects given creatine (8g) for five days prior to a mathematical test noted a relative decrease in oxygenation hemoglobin in the brain and an increase in deoxygenated hemoglobin, which normally indicates a reduction in cerebral oxygenation.[245] The authors made note of how cytoplasmic phosphocreatine can increase oxygen uptake into cells (noted in vitro in a concentration dependent manner between 0-25mM[245]) and suggested that either cells were taking up more oxygen from hemoglobin, or that increased mitochondrial efficiency resulted in less of a need for oxygen.[245]
The other two, the medius and minimus, work together to aid your gluteus maximus in raising your leg to the side. Plus, those smaller glute muscles help rotate your thigh outwards when your leg is straight, and inwards when your hips are bent. Talk about a dream team!

“Reg Park’s theory was that first you have to build the mass and then chisel it down to get the quality; you work on your body the way a sculptor would work on a piece of clay or wood or steel. You rough it out””the more carefully, the more thoroughly, the better”” then you start to cut and define. You work it down gradually until it’s ready to be rubbed and polished. And that’s when you really know about the foundation. Then all the faults of poor early training stand out as hopeless, almost irreparable flaws. [..]
Stand lunge-length in front of a bench making sure your knee does not extend past your toes. Hold a dumbbell in each hand and rest the top of your left foot on the bench behind you. Lower your body until your rear knee nearly touches the floor and your front thigh is parallel to the floor. Then push through the heel of your front foot to return to standing, keeping the back foot on the bench. Repeat for required reps then switch legs.
By that logic, a 160-pound man should consume around 160 grams of protein a day—the amount he'd get from an 8-ounce chicken breast, 1 cup of cottage cheese, a roast-beef sandwich, two eggs, a glass of milk, and 2 ounces of peanuts.) If you don't eat meat for ethical or religious reasons, don't worry — you can count on other sources, too. Soy, almonds, lentils, spinach, peas, and beans are packed with protein.
One case study on a subject with a methylentetrahydrofolate reductase (MTHFR) 677TT homozygote, a relatively common genetic mutation known as “mild MTHFR deficiency,” which causes mild homocysteinemia,[310] has seen benefits due to creatine supplementation where homocysteine was approximately halved (49% reduction) while CT heterozygotes and CC homozygotes (n=9) were unaffected.[311] Additionally, one rat study suggested a possible role for creatine in reducing homocysteine levels in a model of high uric acid levels (model for end stage renal disease[312]) but this was not replicated when investigated in humans.[313]
I learned from this to focus on the body weight exercises. I never understood why I could lift a lot of weight, but felt weak when it came to dips, pull ups, push ups etc. Normally I spend 2 hours in a gym: 20 min jogging, 80 min lifting, 20 min jogging, 5 days a week. After reading this I’m excited to incorporate HIIT training in addition to mobility training on my off days, because I think I was wasting a lot of time and effort. I can push way harder on lifting days without the jog beforehand, so I’ll also be able to make the most of 60 minutes…

^ "The History of Weightlifting". USA Weightlifting. United States Olympic Committee. Archived from the original on 7 July 2013. Retrieved 3 September 2018. The genealogy of lifting traces back to the beginning of recorded history where man's fascination with physical prowess can be found among numerous ancient writings. A 5,000-year-old Chinese text tells of prospective soldiers having to pass lifting tests.
These protective effects are similar to those seen with trimethylglycine, since they both cause an increase in liver concentrations of phosphatidylcholine (PC, causing an increase in vLDL production and efflux of triglycerides from the liver).[497] Both TMG and creatine are thought to work indirectly by preserving SAMe concentrations,[125][498] since PC synthesis requires SAMe as well (via PEMT[499]) and genes involved in fatty acid metabolism in the liver that were not affected by the diet (VLCAD and CD36) were unaffected by creatine.[125]
Several studies have used either beet root juice or pomegranate extract in multi-ingredient performance supplements and have observed improvements in strength, hypertrophy, and performance in resistance-trained men. At this point, however, it's difficult to determine if these benefits are from beet root juice and pomegranate extract working alone or synergistically with other ingredients.[11,12]
Some ingredients found in dietary supplements marketed for bodybuilding or performance enhancement—such as whey protein, creatine, and caffeine—generally aren’t associated with any serious safety concerns (when used appropriately). However, they still have the potential for side effects. Before you take any dietary supplement, talk to your healthcare provider. You also can read the articles below about some of these ingredients:
That means it's an important part of your overall fitness and it benefits people of all ages, plus it may be particularly important for people with health issues such as obesity, arthritis, or a heart condition. The Centers for Disease Control Prevention physical activity guidelines recommend that adults do muscle-strengthening activities on at least two or more days each week (targeting the legs, hips, back, abdomen, chest, shoulders, and arms). (2)
Some anti-aging physicians also use sublingual ( taken under the tongue) forms of non-bioidentical testosterone like oxandrolone. I took oxandrolone with a physician’s guidance for about two weeks, and I got pimples and hair loss. I quit and was bummed that it didn’t generate enough impact to write a blog post about it. I have continued to recommend bioidentical testosterone since.
D-aspartic acid can also help to reduce cortisol levels. Cortisol is known as the “stress” hormone because its production increases during stressful situations. High cortisol levels can have many negative side effects, such as weight gain, muscle tissue breakdown, or increased blood sugar. Taking a supplement that includes cortisol can reduce stress and prevent excess fat storage or muscle loss.
The largest determiner of your metabolic rate is actually your total body mass. “The more cells, even fat cells, in your body, the more furnaces you have burning at any given time,” Dr. Church says. Think of it this way: It takes more juice to charge your tablet than it does to charge your phone. People who are taller and have a larger bone structure, therefore, will have a higher BMR than people who are shorter and have a slimmer build. While you can control your body mass to some extent by gaining or losing weight, you can’t change your height or your bone structure. All in all, most of a person’s BMR is determined by genetic factors, Dr. Church says.

Some people might not think of creatine as a nootropic, but it certainly is one. Creatine supplementation increases energy stores in the brain, typically raising brain creatine content by 5 to 15%. This may be one way by which creatine delays mental fatigue and enhances working memory (that limited, short-term capacity that you use to memorize things like new numerical sequences). Creatine has even been shown to boost a measure of overall intelligence. One study that I find particularly interesting reported that creatine supplementation offsets the adverse effects of sleep deprivation on balance, mood, and reaction time.

One thing to be careful of when exercising the glutes is to resist clenching the butt during backbends or other movements, since this can aggravate the lower back and sacroiliac (SI) joint. To help activate your glutes, try to squeeze the butt in first (before doing any movements) in order to know that you’re using the right muscles, but then release before moving into other postures. Your spine should remain upright, your core engaged and your tailbone tucked as much as possible during yoga or other exercises. The hips should also not be externally rotated, which is easier if you use a block between your thighs in many poses for assistance. (8)
In weight training, as with most forms of exercise, there is a tendency for the breathing pattern to deepen. This helps to meet increased oxygen requirements. Holding the breath or breathing shallowly is avoided because it may lead to a lack of oxygen, passing out, or an excessive build up of blood pressure. Generally, the recommended breathing technique is to inhale when lowering the weight (the eccentric portion) and exhale when lifting the weight (the concentric portion). However, the reverse, inhaling when lifting and exhaling when lowering, may also be recommended. Some researchers state that there is little difference between the two techniques in terms of their influence on heart rate and blood pressure.[8] It may also be recommended that a weight lifter simply breathes in a manner which feels appropriate.
According to the two meta-analyses on the topic, creatine significantly increases power when supplemented in both sexes over a period of time up to 8 weeks, during which improvement over placebo is maintained, rather than being enhanced further. The rate at which power is derived from a resistance training regimen appears to be up to 78.5% greater with creatine relative to placebo, and in active trained men who are naive to creatine, this can be quantified at about 7kg for the bench press and 10kg for the squat over 8 weeks.
Despite a possible decreasing creatine content in the muscles when maintenance is deemed suboptimal, the overall retention of weight and lean mass is merely additive over time. This is thought to be due to increases in skeletal muscle production (increase in body weight) compensating for the progressive declines in water and glycogen content (decreases in body weight).
Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.[81] The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.[81] Thus it is the challenge of competition among males of the species that facilitates aggression and violence.[81] Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.[81] The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[81]
I can’t predict what sort of results you’ll see in that first year, but it can be pretty epic if you attack it right! Muscle growth might happen slower than you want, but I expect something different will happen along the way – you’ll fall in love with this idea of building STRENGTH! In fact, getting hooked on progress, and strength training is one of the best things you can do for yourself. 

Glutes have been enjoying a moment for awhile now, as #BootyGoals and #BootyGains are a coveted asset, so to speak, in the fitness world. Popular aesthetics aside, the quest for strong, powerful glutes is a good thing, as your large posterior muscles not only help you stand, sit, lift, and climb, but they also stabilize your pelvis and can help prevent back pain. Although you use your glutes to sit on your bike, cycling—depending on where and how you ride—doesn’t always build these important muscles.
Nephrotoxic drugs. Because taking high doses of creatine might harm your kidneys, there is concern about combining creatine with drugs that might damage the kidneys (nephrotoxic drugs). Potentially nephrotoxic drugs include nonsteroidal anti-inflammatory drug (NSAIDs) such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve, others), cyclosporine (Neoral, Sandimmune) and others.

The majority of your workouts should be comprised of compound exercises. Common examples include squats, deadlifts, lunges, bench presses, rows, pull-ups, lat pull-downs, overhead presses, and so on. Isolation exercises should definitely also be a part of your program, just a smaller part in comparison. Common examples include bicep curls, tricep extensions, chest flies, lateral raises, leg curls, leg extensions, calf raises, and so on. 

Lie on your back with knees bent and feet flat on the floor. Lift your hips to come into a bridge position. Lift your left leg off the ground and extend it in front of you, keeping your pelvis level. Inhale as you slowly lower your hips toward the ground. Exhale as you drive your right heel into the ground and lift your hips. Do 10-12 reps. Switch sides.
Due to this relative deficiency-state in vegetarians and vegans, some aspects of creatine supplementation are seen as more akin to normalizing a deficiency, rather than providing the benefits of supplementation. In young vegetarians, but not omnivores, creatine supplementation can enhance cognition.[60][61] The increased gain in lean mass may be more significant in vegetarians, relative to omnivores.[59] Supplementation of creatine in vegetarians appears to normalize the gap in storage between vegetarians and omnivores.[62] This is possibly related to a correlation seen in survey research, where vegetarianism and veganism appear to be more commonly affected by some mental disorders like anxiety and depression.[63]
In fact, in one new study comparing the effects of aerobic exercise versus resistance training on the psychological health of obese adolescents, researchers found that people in the resistance group experienced significantly greater self-esteem and perceived strength over four weeks. But what’s most interesting is that the feeling of getting stronger — rather than any measurable gains — was all it took to give them a boost.
From a standing position, balance yourself on your left leg. With your right leg straight and slightly off the floor, perform small circles (from the hip) in front, to the side, and then behind you. Aim for 3-5 circles both clockwise and counterclockwise at each angle. Your supporting leg glutes will be firing to stabilize your pelvis so be sure to stand tall and strong – no swaying.

A meta-analysis found that creatine treatment increased muscle strength in muscular dystrophies, and potentially improved functional performance.[57] Creatine treatment does not appear to improve muscle strength in people who have metabolic myopathies.[57] High doses of creatine lead to increased muscle pain and an impairment in activities of daily living when taken by people who have McArdle disease.[57]


Creatine has been shown before in vitro to protect from MPTP-induced toxicity, which targets dopaminergic neurons in the substantia nigra and induce Parkinson’s disease in research animals.[235] Creatine also protected these cells from death induced by low oxygen or glucose.[574] One study noted that dopaminergic cell survival under the influence of creatine was 1.32-fold higher than control cells, the soma (cell body) was enlarged by 1.12-fold in these cells,[574] and creatine showed some growth-enhancing effects while helping reducing destruction of dopaminergic neurons by various insults.[574]
Lie on your left side. Rest your head on your left arm. Bend your hips to approximately 45 degrees and bend your knees at 90 degrees. Make sure one hip is lying above the other so your knees are stacked perfectly and your feet are aligned with your back. Now, float the upper leg upwards while keeping your feet in contact with one another, then return. Repeat for required reps, then switch sides.
Older women with knee osteoarthritis given supplemental creatine at 20g for five days followed by 5g for the rest of the twelve week trial experienced improvements in stiffness (52% reduction), pain (45%), and physical function (41%) as assessed by WOMAC, despite no improvements in physical power output relative to placebo.[425] This study paired supplementation and placebo with a mild exercise regimen.[425]

Though weight training can stimulate the cardiovascular system, many exercise physiologists, based on their observation of maximal oxygen uptake, argue that aerobics training is a better cardiovascular stimulus. Central catheter monitoring during resistance training reveals increased cardiac output, suggesting that strength training shows potential for cardiovascular exercise. However, a 2007 meta-analysis found that, though aerobic training is an effective therapy for heart failure patients, combined aerobic and strength training is ineffective; "the favorable antiremodeling role of aerobic exercise was not confirmed when this mode of exercise was combined with strength training".[36]
In humans, studies that investigate links between serotonin and creatine supplementation find that 21 trained males, given creatine via 22.8g creatine monohydrate (20g creatine equivalent) with 35g glucose, relative to a placebo of 160g glucose, was found to reduce the perception of fatigue in hot endurance training, possibly secondary to serotonergic modulation, specifically attentuating the increase of serotonin seen with exercise (normally seen to hinder exercise capacity in the heat[233]) while possibly increasing dopaminergic activity (conversely seen to benefit activity in the heat[234]).[155]
A great analogy that I like is that the balance between training and recovery is like digging a hole. Each time you lift, you dig yourself deeper and make it harder to climb out of the hole. To get back out again, you have to fill in the hole to return to ground level, and the only way to fill it is with food and rest. If you overdo it in the gym by pushing too hard, you won’t be able to train as often or at a high capacity. Eventually, you’ll get injured.
The creatine kinase (CK) enzyme in rat heart tissue appears to have a KM around 6mM of creatine as substrate.[280] and is known to positively influence mitochondrial function as higher cytoplasmic phosphocreatine concentrations (not so much creatine per se) increase the oxidative efficiency of mitochondria[280] This is thought to be due to the transfer of high energy phosphate groups.[280]
Your basal metabolic rate (BMR)—the calories you burn just to live—is driven by a host of factors, including your sex, genetics, and age, Tim Church, M.D., professor of preventative medicine at Pennington Biomedical Research Center at Louisiana State University, tells SELF. Research published in the medical journal PLOS ONE also shows that the size of your internal organs plays a huge role in why some people burn more calories at rest than others—in fact, the study found that 43 percent of the differences between people’s metabolic rates can be explained by organ size.

Creatine is a hydrophilic polar molecule that consists of a negatively charged carboxyl group and a positively charged functional group [64]. The hydrophilic nature of creatine limits its bioavailability [65]. In an attempt to increase creatines bioavailability creatine has been esterified to reduce the hydrophilicity; this product is known as creatine ethyl ester. Manufacturers of creatine ethyl ester promote their product as being able to by-pass the creatine transporter due to improved sarcolemmal permeability toward creatine [65]. Spillane et al [65] analyzed the effects of a 5 days loading protocol (0.30 g/kg lean mass) followed by a 42 days maintenance phase (0.075 g/kg lean mass) of CM or ethyl ester both combined with a resistance training program in 30 novice males with no previous resistance training experience. The results of this study [65] showed that ethyl ester was not as effective as CM to enhance serum and muscle creatine stores. Furthermore creatine ethyl ester offered no additional benefit for improving body composition, muscle mass, strength, and power. This research did not support the claims of the creatine ethyl ester manufacturers.
Strong glutes also allow for movements such as bending over, squatting down, standing up straight, pushing off the ground (such as to run) and for maintaining other aspects related to proper posture. A 2005 report published in the Journal of Experimental Biology states that “The human gluteus maximus is a distinctive muscle in terms of size, anatomy and function compared to apes and other non-human primates …. Enlargement of the gluteus maximus was likely important in the evolution of hominid running capabilities.” (1)
I get it. Bodybuilding is a subjective sport with judges that determine who wins based on the judges opinions. In the other resistance training sports you win objectively by outperforming your competitors. Bodybuilders also tend to work out differently with little concern for the weight being lifted, so long as the end result is a better-looking body. This can make bodybuilding type training seem narcissistic and shallow. That’s too bad because hard core resistance training athletes can learn a LOT from bodybuilders and how they train.

I’m going to cover this in detail in a bit, but for right now, just know this: it’s VERY possible (and common) to gain weight fast in the hopes of gaining muscle fast. The problem, however, is that the majority of the “weight” a person in this scenario will end up gaining will be body fat rather than muscle mass. This is something that needs to be avoided at all costs, and I’ll show you how a little later.
Carbohydrates play an important role for bodybuilders. They give the body energy to deal with the rigors of training and recovery. Carbohydrates also promote secretion of insulin, a hormone enabling cells to get the glucose they need. Insulin also carries amino acids into cells and promotes protein synthesis.[26] Insulin has steroid-like effects in terms of muscle gains.[27] It is impossible to promote protein synthesis without the existence of insulin, which means that without ingesting carbohydrates or protein—which also induces the release of insulin—it is impossible to add muscle mass.[28] Bodybuilders seek out low-glycemic polysaccharides and other slowly digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat. However, bodybuilders frequently do ingest some quickly digesting sugars (often in form of pure dextrose or maltodextrin) just before, during, and/or just after a workout. This may help to replenish glycogen stored within the muscle, and to stimulate muscle protein synthesis.[29]

But when a premenopausal woman’s testosterone levels are too high, it can lead to polycystic ovary syndrome (PCOS), a condition that increases the risk of irregular or absent menstrual cycles, infertility, excess hair growth, skin problems, and miscarriage. High levels of testosterone in women, whether caused by PCOS or by another condition, can cause serious health conditions such as insulin resistance, diabetes, high cholesterol, high blood pressure, and heart disease.

Progain contains an easily digested source of carbohydrate, providing much needed carbohydrate to fuel your workout before or after. By adding creatine to your diet, in a shake, in food or in capsules, is proven to increase strength, build muscle size and support training intensity. At Maximuscle we have a number of products with added creatine, such as: Creatine Monohydrate, Creatamax Capsules, Cyclone (powder & bars), Progain Flapjack.
There have also been concerns that creatine can cause kidney damage, and doctors warn that people with a history of kidney disease or conditions, such as diabetes, that increase the risk of kidney problems should steer clear of the supplement. Combining creatine with nephrotoxic drugs — drugs that might damage the kidneys — like nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (advil or motrin) and naproxen sodium (Aleve), should also be avoided, according to the U.S. Department of Health and Human Services.

Green tea offers many health benefits, such as inhibition of cardiovascular disease and cancer. It also has some mild thermogenic effects, independent of its caffeine content, that may assist fat loss. Some studies even show that green tea offers protection against joint degeneration. If you don't have the time or inclination to drink several cups of green tea daily, you can get the same or better effects by using standardized capsules or tablets of green tea.

If you want to take creatine as a supplement for bigger and stronger muscles, then the standard protocol is to have a “loading period” where you significantly increase your creatine intake for a few days or weeks. “This can prime your muscles to increase the amount of creatine that they ‘hold,’” explains Bates. “During the loading period, you generally take 5 g of creatine four times per day. After the loading period, you decrease the amount of creatine you take to a ‘maintenance’ level of 3 to 5 g per day.” (That’s also the recommendation from the International Society of Sports Nutrition.)

How to do it: Start by stepping forward into a lunge with your left foot. Place your right forearm to the ground and your left elbow to the inside of your left foot, and hold the stretch for two seconds. Then place your left hand outside of your foot and push your hips up, pointing your front toes up. Return to standing position and repeat by stepping out with your right foot. Continue alternating sides.

That being said, men aren’t the only ones who suffer from low testosterone levels. Women can also suffer from testosterone deficiency which can affect their overall well-being in addition to their sex drive. If you’re a woman or man concerned about your testosterone levels, in addition to using supplements like the ones below, you should contact your doctor who will be able to diagnose any deficiencies and recommend additional treatments.
This post can absolutely change your life, and probably help you avoid some pitfalls. Like shrunken balls. (I am not an expert in the synthetic anabolic testosterone drugs used by bodybuilders — they carry lots of risks but pack a big punch if you want to get swole. Bulletproof is all about having massive clean energy, looking good, and living a very long time…so anabolic steroids aren’t on my roadmap.)

The rise in testosterone levels during competition predicted aggression in males but not in females.[90] Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression.[91] Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations.[92] Testosterone produces aggression by activating subcortical areas in the brain, which may also be inhibited or suppressed by social norms or familial situations while still manifesting in diverse intensities and ways through thoughts, anger, verbal aggression, competition, dominance and physical violence.[93] Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli.[94] Testosterone specific structural brain characteristic can predict aggressive behaviour in individuals.[95]
