As blood levels of testosterone increase, this feeds back to suppress the production of gonadotrophin-releasing hormone from the hypothalamus which, in turn, suppresses production of luteinising hormone by the pituitary gland. Levels of testosterone begin to fall as a result, so negative feedback decreases and the hypothalamus resumes secretion of gonadotrophin-releasing hormone. 
For beginners, your own body weight might be enough to get you started. However, it can be hard to challenge your body without any additional resistance, so to progress, you'll need some equipment. If you decide to strength train at home, you'll want to invest in some basics, such as resistance bands, weights, and an exercise ball. Try to have a range of weights: a light set (3 to 5 pounds for women, 5 to 8 pounds for men), a medium set (5 to 10 pounds for women, 10 to 15 pounds for men), and a heavy set (10 to 20 pounds for women, 15 to 30 pounds for men).

The slider reverse lunge is simple to perform and doesn’t need much in the way of instructions. Simply grab a Valslide, or a similar tool that will allow you to move smoothly across the ground. Put the slide under one foot, and use that foot to slide into a reverse lunge, and then return to standing. Try doing this exercise after one of the ones above, and just wait until you feel the burn!


The participants were seen every 4 weeks. Blood was taken to measure hormone levels, and questionnaires were given to assess physical function, health status, vitality, and sexual function. Body fat and muscle measurements were also taken at the beginning and end of the 16 weeks. The study was funded in part by NIH’s National Institute on Aging (NIA) and National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Results appeared in the September 12, 2013, issue of the New England Journal of Medicine.

The daily requirement of a 70-kg male for creatine is about 2 g; up to half of this may be obtained from a typical omnivorous diet, with the remainder being synthesized in the body ... More than 90% of the body’s creatine and phosphocreatine is present in muscle (Brosnan and Brosnan 2007), with some of the remainder being found in the brain (Braissant et al. 2011). ... Creatine synthesized in liver must be secreted into the bloodstream by an unknown mechanism (Da Silva et al. 2014a)

There are several different available forms of creatine: creatine anhydrous which is creatine with the water molecule removed in order to increase the concentration of creatine to a greater amount than that found in CM. Creatine has been manufactured in salt form: creatine pyruvate, creatine citrate, creatine malate, creatine phosphate, magnesium creatine, creatine oroate, Kre Alkalyn (creatine with baking soda). Creatine can also be manufactured in an ester form. Creatine ethyl ester (hydrochloride) is an example of this, as is creatine gluconate which is creatine bound to glucose. Another form is creatine effervescent which is creatine citrate or CM with citric acid and bicarbonate. The citric acid and bicarbonate react to produce an effervescent effect. When mixed with water the creatine separates from its carrier leaving a neutrally charged creatine, allowing it to dissolve to a higher degree in water. Manufacturers claim that creatine effervescent has a longer and more stable life in solution. When di-creatine citrate effervescent was studied [59] for stability in solution it was found that the di-creatine citrate dissociates to citric acid and creatine in aqueous solutions which in turn forms CM and eventually crystallises out of the solution due to its low solubility. Some of the creatine may also convert to creatinine.
If you have hit a plateau, a good supplement could be all you need to pull yourself out of a slump and make the progress you want to be making. Creatine is widely known as the most effective sports supplement. Scientific studies have proven that creatine maximizes ATP production which is responsible for energy in your body. Essentially, creatine will give you more energy to allow you to do the things that will make you stronger.

We’ll define the “bigger muscle groups” as being chest, back, quads and hamstrings, and the “smaller muscle groups” as being biceps, triceps and maybe abs. Shoulders are really somewhere in the middle, though I tend to lean more toward the “smaller” guidelines. Calves, while technically small, are another muscle group that is somewhere in the middle, and I can really go either way depending on the needs of the person.
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…
Safety. Iron overload may cause a disease called hemochromatosis in some susceptible people. Iron supplements should only be prescribed by a doctor, and for athletes or those who train heavily, a sports physician combined with a sports dietitian may be preferable. Be sure to take care with this because iron supplements should not be taken casually. Iron supplements may cause constipation and gastric upset in some people.
A loading phase of 10g creatine monohydrate for two weeks and 4g for the final week in subjects with MELAS (Mitochondrial Encephalomyopathy Lactic Acidosis and Stroke-like episodes) has been noted to increase physical strength relative to baseline, although the poor VO2 max seen in these subjects was not affected.[549] A case study exists in which a patient with a relatively novel mutation in their mitochondrial function (affecting cytochrome B) experienced benefits from creatine at 10g daily.[550] Researchers examining another case of MELAS found both cognitive and physical benefits with 5g creatine supplementation,[551] while four controlled case studies of 100-200mg/kg daily in children with myopathies found improved muscular endurance (30-57%) and muscular power (8-17%) after 100-200mg/kg daily for at least three months.[552]
Great Paleo beef protein, why? Because it doesn't have any preservatives, fillers, Dairy, soy, yeast, corn, or any other additives. No artificial colorings/flavorings. That makes this product not just paleo, but also autoimmune paleo friendly, hard to find. That basically means anti alergic, you dont get the same digestive issues many people get with whey. I think beef protein is underrated, I just finished a batch and went back to my whey. The whey gives me bloating/gas that this product doesnt. Also if you don't like how the amino acid profile stacks up agains Whey protein powder you can add some BCAA to powder, at least thats what I do. In a 30 gram saving you get 28 grams of protein (zero fat and zero carb), not bad!

If you're a beginner, start with a basic total body strength workout to build a strong foundation in all your muscle groups. Taking this time will help you figure out any weaknesses you have, as well as any issues you may need to address with your doctor, and learn the basic exercises you need for a strong, fit body. Your first step is to figure out where you're going to exercise.


For the sake of mental focus, it’s best to keep any carbs you eat low during the day when you’re working and active and get the lion’s share of them at night with dinner. A typical breakfast could include eggs, yogurt, and fruit, or a shake, and lunch could be meat or fish and steamed veggies. For dinner, have meat or fish again, along with sweet potatoes or rice, and vegetables.

If you're 12 weeks out from a competition, you want to maintain as much muscle as possible while torching fat from every angle. This means low-intensity cardio – high intensity cardio speeds up your metabolism and burns fat very quickly, so you run the risk of burning muscle too, Terry says – either first thing in the morning on an empty stomach, or immediately after your weights session, once you’ve depleted those glycogen levels.
Oral ingestion of 1-1000mg/kg bodyweight of creatine in mice was able to exert an anti-depressive effect, which was blocked by dopamine receptor antagonists. A low dose of creatine (0.1mg/kg) was able to enhance the dopaminergic effects of dopamine receptor activators, suggesting supplemental creatine can positively influence dopamine signaling and neurotransmission.[252]
A recent review article published in The American Journal of Clinical Nutrition highlighted the benefits of protein supplementation and showed that supplementing with protein during prolonged (greater than 6 weeks) resistance-type training can lead to significantly greater increases in muscle mass and strength when compared to resistance training without a dietary protein intervention.[15]
If you're using a resistance band, keep in mind that one band might not cut it for your entire body. Different muscles have different strengths, so you may want to buy two different resistance bands in different thickness, which determines how difficult they'll be to use. In general, if you're able to complete 8 reps of an exercise using a band, you'll want to select another that provides a greater amount of resistance. 
Taking high doses of creatine might harm the kidneys. Some medications can also harm the kidneys. Taking creatine with medications that can harm the kidneys might increase the chance of kidney damage.

Some of these medications that can harm the kidneys include cyclosporine (Neoral, Sandimmune); aminoglycosides including amikacin (Amikin), gentamicin (Garamycin, Gentak, others), and tobramycin (Nebcin, others); nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen (Advil, Motrin, Nuprin, others), indomethacin (Indocin), naproxen (Aleve, Anaprox, Naprelan, Naprosyn), piroxicam (Feldene); and numerous others.

The researchers found that the dose of testosterone required to produce different effects in the body varied widely. The influence of testosterone and estradiol also differed. As the testosterone gel dose was reduced, the scientists showed, reductions in lean mass, muscle size, and leg-press strength resulted from decreases in testosterone itself. In contrast, increases in body fat were due to the related declines in estradiol. Both testosterone and estradiol levels were associated with libido and erectile function.
Co-ingesting creatine with caffeine partially negated the benefits of creatine supplementation (at 5mg/kg bodyweight) during the loading phase in one study.[590] The exact mechanism responsible for this effect is not known, but might be related to opposing actions on muscle contraction time.[591] However, another study in trained men found that co-ingestion of 300mg caffeine per day during creatine loading at 20g per day (split into 4 doses) had no effect on bench press 1RM, time to fatigue, or sprinting ability.[592] However, this study also found that creatine alone or when combined with caffeine had no effect on any of these parameters over placebo, either. Thus, the study may have been underpowered or done in too short a time frame (the test was done after only 5 days of loading) to observe any possible effects.[592]
 Besides the obvious benefits of getting protein into your system, our vegan protein powder offers other benefits too. It’s one of the one of the best bodybuilding supplements for anyone –– regardless of their diet –– because it’s a Smooth Protein™. That means it’s organic, non-GMO, gluten-free, and non-allergenic, and it also doesn’t have that gritty texture and earthy flavor associated with other plant-based protein supplements.

Neurological and cognitive function has also been shown to be improved by creatine supplementation [47,48]. Rawson and Venezia [49] review the effects of creatine supplementation on cognitive function highlighting that higher brain creatine has been associated with improved neuropsychological performance. Creatine supplementation protocols have been shown to increase brain creatine and phosphocreatine contents. Cognitive processing hindered due to sleep deprivation and natural impairment due to aging can be improved by creatine supplementation. This review also highlights other possible benefits of creatine ingestion to older adults, such as improvements in: fatigue resistance, strength, muscle mass, bone mineral density, and performance of activities of daily living. Some of these benefits occur without concurrent exercise. The authors inform that discrepancies between studies do exist and are hard to explain but may be possibly due to differences in diet, race and/or supplementation protocols. However, the ideal dose of creatine to maximize brain uptake is not known. Patients have been supplemented with 40 g while in healthy adults positive results have been reported with around 20 g per day [49].

Generally, you should consume about 20 grams of protein with some carbs shortly after a workout. During the post-workout anabolic window, you’ll also want to limit fats, which can slow the absorption of protein. While there is some recent research that suggests the window may actually extend up to several hours following exercise, there’s no harm in getting nutrients in early as long as you’re sticking to your overall caloric and macronutrient goals.

Another part of training isn't just doing the exercises, it's resting between the exercises. This comes with experience, but the general rule is, the higher the reps, the shorter the rest. So, if you're doing 15 reps, you might rest about 30 to 60 seconds between exercises. If you're lifting very heavy, say 4 to 6 reps, you may need up to two or more minutes.
The doctor regularly measured my levels to be sure they were within the normal range for a male my age. In other words, I wasn’t taking ‘roids to get big; I was getting control of hormones that were not functioning well. This is how you should look at testosterone therapy – it is a gentle nudge to help you be in normal ranges, not a big push to get you huuu-yge. If you’re like me, you want “normal ranges” of a 27-year-old, not of a 60-year-old. It’s my plan to keep my testosterone where it is now (around 700) no matter what it takes. Right now, the Bulletproof Diet and the other biohacks I’ve written about do that! I’m 43.
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.
This concept of timing has been applied to everything from fat burners, protein supplements, carbohydrates, and various other supplements. In some cases, you can see a difference based on when you take a product. But more often, the timing is based more on anecdotal evidence than any hard science. Recently, this nutrient timing aspect has even been extended to creatine, a product that is so effective that it’s worth the investigation of determining if there’s an element that can give you even greater benefits.
Creatine, the amino acid, naturally helps your body produce more adenosine triphosphate, or ATP, a small molecule that’s actually your body's primary energy source. But research shows that your body is only capable of storing enough ATP for 8 to 10 seconds of high-intensity exercise — and after that, it needs to produce new ATP for you to continue. (9)
Growth of spermatogenic tissue in testicles, male fertility, penis or clitoris enlargement, increased libido and frequency of erection or clitoral engorgement occurs. Growth of jaw, brow, chin, and nose and remodeling of facial bone contours, in conjunction with human growth hormone occurs.[21] Completion of bone maturation and termination of growth. This occurs indirectly via estradiol metabolites and hence more gradually in men than women. Increased muscle strength and mass, shoulders become broader and rib cage expands, deepening of voice, growth of the Adam's apple. Enlargement of sebaceous glands. This might cause acne, subcutaneous fat in face decreases. Pubic hair extends to thighs and up toward umbilicus, development of facial hair (sideburns, beard, moustache), loss of scalp hair (androgenetic alopecia), increase in chest hair, periareolar hair, perianal hair, leg hair, armpit hair.
Remember, this is for the extreme skinny guy...But I want you to start hitting a buffet once a week. Try and position this eating frenzy after a hard workout so that the majority of calories get shuttled into the muscles which will really help you pack on those pounds and gain weight in the right places. Don't go too overboard, but this will train your body to 'accept' more food and it will increase your appetite in the days to come. Take advantage of this strategy.
How to do it: Balance on your right foot, keeping your midsection tight and shoulders back and down. Bend at the waist with both of your hands out to the sides and extend your left leg back as you fire the left glute. Your shoulder and heel should move together, forming a straight line. Return to starting position and switch legs, performing a set of 10 on each leg.
The gluteus maximus can be your best friend when it comes to safely 
performing backbends. Yet overusing this big muscle by clenching your butt as you backbend can lead to irritation and injury in the spine and sacroiliac (SI) joint. In order to mitigate excessive spinal compression in backbends, it’s helpful to use the buttocks and adductors (inner thighs) to support the weight of the pelvis, hips, and spine. Work on the following actions:
Research shows that strength training is especially effective at raising EPOC. That’s because, generally speaking, strength-training sessions cause more physiological stress to the body compared to cardiovascular exercise, even higher-intensity cardio intervals. However, it’s worth noting that overall exercise intensity is what makes the biggest impact on EPOC. So squats, deadlifts, and bench presses with heavy weights are going to be much more effective at raising EPOC compared to bicep curls and triceps extensions with light weights.
It is regularly reported that creatine supplementation, when combined with heavy resistance training leads to enhanced physical performance, fat free mass, and muscle morphology [18-22]. A 2003 meta analysis [8] showed individuals ingesting creatine, combined with resistance training, obtain on average +8% and +14% more performance on maximum (1RM) or endurance strength (maximal repetitions at a given percent of 1RM) respectively than the placebo groups. However, contradicting studies have reported no effects of creatine supplementation on strength performance. Jakobi et al [23] found no effects of a short term creatine loading protocol upon isometric elbow flexion force, muscle activation, and recovery process. However, this study did not clearly state if creatine supplementation was administered concurrent with resistance training. Bemben et al [24] have shown no additional benefits of creatine alone or combined with whey protein for improving strength and muscle mass after a progressive 14 weeks (3 days per week) resistance training program in older men. These conflicting results can be explained by the possibility that the supplemented groups were formed by a greater amount of non-responders or even because creatine supplementation was administered on the training days only (3 times a week). This strategy has not been adequately tested as effective in middle aged and older men for maintaining post loading elevated creatine stores [5].
If there are any benefits for swimming performance from creatine supplementation, they appear to be limited to a 50 meter sprint or a handful of 50 meter sprints with short intermissions. Excessive sprinting (over six sprints with short breaks) or too long of a break (five minutes rather than two) seem to not be associated with the benefits of creatine supplementation.

Bodybuilding supplements are dietary supplements commonly used by those involved in bodybuilding, weightlifting, mixed martial arts, and athletics for the purpose of facilitating an increase in lean body mass. The intent is to increase muscle, increase body weight, improve athletic performance, and for some sports, to simultaneously decrease percent body fat so as to create better muscle definition. Among the most widely used are high protein drinks, branched-chain amino acids (BCAA), glutamine, arginine, essential fatty acids, creatine, HMB,[1] and weight loss products.[2] Supplements are sold either as single ingredient preparations or in the form of "stacks" – proprietary blends of various supplements marketed as offering synergistic advantages. While many bodybuilding supplements are also consumed by the general public the frequency of use will differ when used specifically by bodybuilders. One meta-analysis concluded that for athletes participating in resistance exercise training and consuming protein supplements for an average of 13 weeks, total protein intake up to 1.6 g/kg of body weight per day would result in an increase in strength and fat-free mass, i.e. muscle, but that higher intakes would not further contribute.[3] The muscle mass increase was statistically significant but modest - averaging 0.3 kg for all trials and 1.0–2.0 kg, for protein intake ≥1.6 g/kg/day.[3]

In 1912, Harvard University researchers Otto Folin and Willey Glover Denis found evidence that ingesting creatine can dramatically boost the creatine content of the muscle.[5][non-primary source needed] In the late 1920s, after finding that the intramuscular stores of creatine can be increased by ingesting creatine in larger than normal amounts, scientists discovered creatine phosphate, and determined that creatine is a key player in the metabolism of skeletal muscle. The substance creatine is naturally formed in vertebrates.[6]
Muscle imbalances are quite common among strength athletes and are arguably the most common cause of their injuries. Many times this is due to a “weak link” in the kinetic chain of muscles that activate during their activity. Identifying the “weak” muscle and being able to feel, isolate and contract that “weak” muscle makes correctional exercise and rehab much easier. Bodybuilding training, with its focus on “feel” rather than movement, helps to train and develop the mind to muscle connection. This comes in handy when you need to train a muscle imbalance with correctional exercise and, in the case of injury, for rehab.
COX-2, a pro-inflammatory enzyme, is sometimes a therapeutic target for both muscle soreness and some degenerative diseases that are exacerbated by inflammation. COX-2 inhibitors (in this study, rofecoxib) and creatine monohydrate both appear to protect dopaminergic neurons from being destroyed by toxins, and can protect in an additive manner, suggesting possible usage of both to reduce the risk of Parkinson’s disease.[230]
If you reflect on the effects of creatine supplementation within cells, you can probably come up with numerous conditions in which creatine may help people prevent or overcome morbidity. Sometimes, for example, energy supply to tissues is temporarily compromised, as in the case of impaired blood flow to the brain (cerebrovascular disease) or heart (myocardial ischemia). Sure enough, there’s preliminary evidence that creatine may help in these pathologies.
Testosterone is most commonly associated with sex drive in men. It also affects mental health, bone and muscle mass, fat storage, and red blood cell production. Abnormally low or high levels can affect a man’s mental and physical health. Your doctor can check your testosterone levels with a simple blood test. Testosterone therapy is available to treat men with low levels of testosterone. If you have low T, ask your doctor if this type of therapy might benefit you.
However, testosterone is only one of many factors that aid in adequate erections. Research is inconclusive regarding the role of testosterone replacement in the treatment of erectile dysfunction. In a review of studies that looked at the benefit of testosterone in men with erection difficulties, nearly half showed no improvement with testosterone treatment. Many times, other health problems play a role in erectile difficulties. These can include:
In general, muscle content of creatine tends to be elevated to 15-20% above baseline (more than 20mM increase) in response to oral supplementation. People who get a sufficiently high influx of creatine are known as responders.[150][151][152][153] A phenomena known as “creatine nonresponse” occurs when people have less than a 10mM influx of creatine into muscle after prolonged supplementation.[154] Quasi-responders (10-20mM increase) also exist.[154] Nonresponse is thought to explain instances where people do not benefit from creatine supplementation in trials, since some trials that find no significant effect do find one when only investigating people with high creatine responsiveness.[155] There are clear differences between those who respond and those who do not, in regard to physical performance.[156] People who are creatine responsive tend to be younger, have higher muscle mass and type II muscle fiber content, but this has no correlation with dietary protein intake.[154][157]
How to do it: Lie on your back with your feet planted firmly on the floor, knees bent. If you’re just starting and using your bodyweight, reach your arms straight up over your chest and clasp your hands. If you’re using dumbbells, place the weight (plate, kettlebell, dumbbells) comfortably on your pelvis and hold it steady. To really activate your glutes, thrust your hips up toward the ceiling, driving with your legs, and dig your heels into the floor. Lower your hips until they’re hovering right above the floor level, then repeat.  
Once training is resumed under these conditions, there may be little in the way of caloric support to ensure that protein synthesis and muscle growth occurs. Muscle may even begin to cannibalize itself as the body enters into a catabolic state. Even with the best of diets this can sometimes happen if training demands override the nutritional balance or imbalance.
Perhaps 1 to 2% of intramuscular creatine is degraded into creatinine each day, which is excreted in urine. Therefore, approximately 1 to 3 g of creatine needs replenishing daily to maintain basal levels. Some of this replacement is fulfilled by the liver and kidneys, which can use the amino acids arginine and glycine to synthesize creatine. A tiny minority of people has gene mutations that result in impaired creatine synthesis or transport. These unfortunate people experience severe neurodevelopmental problems beginning early in life and benefit from consuming more creatine in their diets.

How much weight? Start with a pair of light dumbbell hand weights (2 to 3 pounds for women and 5 to 8 pounds for men). If you can’t do 12 repetitions (or reps are the number of times you do the exercise) the weight is too heavy. If your muscles don’t feel tired after 12 reps, it’s too light. Adjustable weights that can be strapped to wrists or ankles may be convenient if you have arthritis in your hands. You can also use home or gym weight machines, or resistance bands.
