After all, if you’re doing more reps in a set, the weight would obviously be lighter and the intensity level lower. If you’re doing fewer reps in a set, the weight is obviously heavier and the intensity is higher. In addition, how close you come to reaching failure – aka the point in a set when you are unable to complete a rep – also plays a role here.

I’m glad you found some good information from this article. For any of these supplements, I would suggest talking to your doctor and pharmacist. I would suggest thinking about why you are interested in taking testosterone. Are you looking to increase muscle size? Bulk up? Knowing your fitness goals will help you determine which products are appropriate for you.
Moving through repetitions too quickly, going too fast; there is nothing gained by lifting weights fast. Some of the perks of lifting weight in a slow and controlled manner, include more total muscle tension and force produced, more muscle-fiber activation both slow and fast twitch fibers, and less tissue trauma. Remember, a joint is only as strong as the muscles that cross it; if you haven't lifted in a long time, or ever, be careful what you ask of your joints.
The muscle strength objective is pursued when you want your muscles to be effective when a high number of repetitions will be involved, or in other words when you want your muscles to be strong for a continued period of time. You'll want to use approximately 4 sets from which 10-12 reps are performed. The muscle strength objective is often used for muscles located in your back and your abdominals.
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.
When lifting any weight, you’ve got a concentric (hard) and eccentric (easy) phase. For instance, as you lower into a squat, you’re performing an eccentric action. When you return to standing, that’s concentric. And, according to research published in the European Journal of Applied Physiology, eccentric work is far better at triggering hypertrophy.

Don’t get us wrong—cardio is important for keeping your body fat down and keeping your heart health in check. (Bonus points if you run or bike, since outdoor exercise is linked to better energy and improved mental health.) But when it comes to building muscle, hitting the treadmill won't help you much. “Every component of exercise, minus cardio, can help with muscle hypertrophy,” which is the scientific term for muscle building, says Michelle Lovitt, an exercise physiologist and trainer in Los Angeles. “Cardio tends to burn calories and puts your body in a deficit, which is great for leaning out, but not building mass.”


But one question has repeatedly popped up: When is the best time to take creatine? Recent research has suggested that there might be an ideal time. That’s when I decided to speak with the supplement experts at Examine.com. For those of you who don’t know, they have created the world’s largest database of facts about supplements. No marketing BS. Just a bunch of Ph.D’s, PharmD’s, and biomedical researchers who are obsessed with sharing the truth. Their Supplement Guide is the best thing written about supplements since…well…ever. If you’ve ever had a question it’s pack with research and fact-based information to help you make healthier supplement choices.
Research shows that starting as early as age 30, the body begins to slowly lose muscle mass, with women losing up to 15 percent of their total-body muscle per decade by age 50. Apart from declines in strength, that declining muscle mass comes with a declining metabolism, Emilia Ravski, D.O., a sports medicine specialist with Hoag Orthopedic Institute in California, tells SELF. This decline in metabolic rate is actually one driving factor of the weight that women generally tend to put on after we naturally hit our peak muscle levels in our 20s, research from Tufts University suggests.

Perform bent over rows to work your back. Stand with your feet shoulder-width apart, about 6 to 10 inches (15–25 cm) behind the barbell or two dumbbells. Bend slightly at the knees but keep your shins vertical. Bend forward at the waist with your spine and head straight. Lift the weight with an overhand grip up to your lower chest or upper abdomen. Lower slowly until your arms are nearly extended, without touching the ground. 3 x 8.[5]


Eat 0.4–0.5 grams of fat per pound of your body weight. Fat is essential for hormone optimization, brain function, and joint health. Now, if you’re following a ketogenic diet (or modified keto diet), or you just feel better with more fat in your diet, you can certainly add more fat and lower your protein and carb intake to accommodate it. The 0.4–0.5 grams per pound recommendation just represents a starting point and a minimum so that you don’t eat too little fat, either out of fear that it will make you fat or damage your heart (both untrue). For more about ketogenic diets, see Onnit’s guide HERE.

Extracellular creatine (creatine outside of a cell) appears to influence creatine uptake into a cell. It seems that prolonged and excessive levels of creatine actually suppress uptake (a form of negative regulation to prevent excessive influx).[180] In vitro studies in rat muscle cells have shown that including 1mM creatine into cell culture medium substantially reduces creatine uptake into cells. The inhibitory effect was partially negated by protein synthesis inhibitors, suggesting that high levels of creatine induce the expression of a protein that suppresses creatine transporter activity.[180] Similar findings were reported in a later study in cultured mouse myoblasts, which noted a 2.4-fold increase in intracellular creatine levels in the presence of the protein synthesis inhibitor cyclohexamide.[174]
"It'’s especially important to eat a carb- and protein-rich meal immediately after a workout," Aceto says. "Right after training, it turns out that your body is really lousy at taking carbohydrates and sending them down fat-storing pathways,"” he says. "So post-training, carbs will be sent down growth-promoting pathways instead."” And when these carbs are combined with a protein source, you'’ve got a strong muscle-feeding combination because carbohydrates help deliver the amino acids into muscles by boosting insulin levels. This anabolic hormone drives nutrients into the muscle cells and kick-starts the muscle-growth process.
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.
No need to worry! This myth that caffeine counteracts creatine came from the simple, but wrong logic that because caffeine accelerates the nervous system and uses more water, it would counteract creatine because creatine helps your body retain water. While both of these statements are true, it does not mean they “cancel” eachother out, all that it means is that your body will be able to stay hydrated longer if you are taking creatine and caffeine opposed to just taking caffeine.
So it was popular then, but is it effective now? Just because something is popular doesn’t mean it works. In the case of creatine supplementation, however, you can be confident that increased muscle strength and less fatigue is possible. All thanks to a critical chemical reaction taking place in your muscle cells. Read on and learn how creatine works and why it lives up to that nostalgic ‘90s hype.
The major controversies regarding creatine are its side effects and the best form to use. Nearly all side effects attributed to creatine, such as muscle cramps, kidney disease and gastrointestinal disturbances, haven't proved significant under controlled scientific scrutiny. Although various claims are made for a variety of creatine supplements, creatine monohydrate, which is 99 percent absorbed, is the best form to use.

More specifically, you can expect to end up in the upper half of these ranges ONLY if you are a beginner, younger, and/or have amazing genetics. You can expect to end up in the lower half of these ranges if you are an intermediate or advanced trainee, older, and/or have poor genetics. The average person can expect to end up somewhere in the middle. Additional details here: How Much Muscle Can You Gain?
That means it takes time for supplements aimed at joint treatment to work. So plan not to feel anything for about two months after you start using glucosamine. After that, pain control with the supplement is comparable to what happens with drug use, according to various studies. The typical doses are 1,200 milligrams daily of glucosamine and 800 of chondroitin, which can be doubled initially.
Creatine has been noted to increase the amplitude (0.5-5mM) and frequency (25mM only) of NMDA receptors, although concentrations of 0.5-25mM also reduced signaling intensity. This was credited to creatine causing an increase in ligand binding of glutamate with an EC50 of 67µM and maximal activity at 1mM creatine (158±16% of baseline).[214] Creatine appears to modulate the polyamine binding site of the NMDA receptor, as it is abolished by arcaine and potentiated by spermidine.[215] This binding site is known to modify NMDA receptor affinity.[216][217]
Collectively the above investigations indicate that creatine supplementation can be an effective strategy to maintain total creatine pool during a rehabilitation period after injury as well as to attenuate muscle damage induced by a prolonged endurance training session. In addition, it seems that creatine can act as an effective antioxidant agent after more intense resistance training sessions.
In summary, creatine salts have been show to be less stable than CM. However the addition of carbohydrates could increase their stability [62]. The potential advantages of creatine salts over CM include enhanced aqueous solubility and bioavailability which would reduce their possible gastrointestinal adverse effects [63]. The possibility for new additional formulation such as tablets or capsules is interesting for its therapeutic application due to its attributed better dissolution kinetics and oral absorption compared to CM [63]. However more complete in vivo pharmaceutical analysis of creatine salts are required to fully elucidate their potential advantages/disadvantages over the currently available supplement formulations.
Creatine retention (assessed by urinary analysis) tends to be very high on the first loading dose (65±11%) and declines throughout the loading phase (23±27%).[203] This is likely due to increased muscular uptake when creatine stores are relatively low, which has been noted in vegetarians. So, creatine absorption is very high initially, but decreases througout the loading phase, as muscle creatine stores increase.[204]
In October 1994, the Dietary Supplement Health and Education Act (DSHEA) was signed into law in the USA. Under DSHEA, responsibility for determining the safety of the dietary supplements changed from government to the manufacturer and supplements no longer required approval from the U.S. Food and Drug Administration (FDA) before distributing product. Since that time manufacturers did not have to provide FDA with the evidence to substantiate safety or effectiveness unless a new dietary ingredient was added. It is widely believed that the 1994 DSHEA further consolidated the position of the supplement industry and lead to additional product sales.[6]

Foundational supplements are often overlooked for building muscle, because they work behind the scenes. In actuality, foundational supplements are important to take for building muscle, because they assist with overall health and wellness and contribute to the effectiveness of other muscle building supplements.* Some of the top foundational supplements are:
If your fitness goals are to get strong and build hard, visible muscle, then you’re going to want to train in three phases according to Heath. Strength, conditioning, and a blend of the two that works for you. “If you can get to the gym 4-5 days a week, that would be perfect,” he says. “You can still do chest/tri’s, back/bi’s, legs, shoulders, and make the fifth day a cleanup day, meaning focus on body parts you may be weaker in.” Check out Heath’s guide to finding your best muscle-building routine.

This increased permeability is noted in glioma cells, where it exerts anti-cancer effects related to cell swelling,[99][100] and in other membranes, such as breast cancer cells[101] and skeletal (contractile) muscle cells.[102] The kinetics of cyclocreatine appear to be first-order,[101] with a relative Vmax of 90, Km of 25mM and a KD of 1.2mM.[103]

Stronger muscles improve performance in a variety of sports. Sport-specific training routines are used by many competitors. These often specify that the speed of muscle contraction during weight training should be the same as that of the particular sport. Sport-specific training routines also often include variations to both free weight and machine movements that may not be common for traditional weightlifting.
However, in the beginning weeks of starting a new workout routine, the majority of strength gains aren't actually a result of this muscle protein synthesis and hypertrophy. Rather, they are a result of the body's neurological system learning when and how to fire the needed muscle cells, explains Abbie E. Smith-Ryan, associate professor of exercise physiology at the department of exercise and sport science at the University of North Carolina–Chapel Hill. Think of it this way: The first time you perform a new exercise, say a bench press, you likely feel pretty shaky. Your arms aren't totally in sync and the weights may sway a bit from side to side. But by the time you perform your second or third set of that same exercise, the practice gets a little smoother. That's your neurological system at work.
Some other cytokines and hormones may increase the receptor activity. These include growth hormone (GH) which acts upon the growth hormone receptor (GHR)[166][167] to stimulate c-Src[168][169] which directly increases the activity of the CrT via phosphorylation. This is known to occur with the 55kDa version of c-Src but not the 70kDa version and requires CD59 alongside c-Src.[170]

Creatine has been found to increase skeletal muscle glycogen when given to sedentary adults for a loading and maintenance phase for 37 days at 2g (13.5% after five days of loading, but returning to baseline at the end of the trial). Exercise was not enforced in this study.[207] This study also noted that, despite a normalization of glycogen after the trial, total creatine and ATP was still higher than placebo,[207] and a loading protocol appears to have failed elsewhere in increasing glycogen stores in sedentary people subject to an aerobic exercise test before and after the loading phase.[349]


I mean the first two ‘BS’ items focal point is lifting heavy, and then immediately the article goes into Step 1 – focus on 5-10 rep and 6-8 rep (heavier sets) — given we’re not powerlifting 1 rep or 3 rep max. Generally 6 rep sets we’re lifting heavy still… Does have a lot of good general info, but to me it almost feels like the bullet points of what supposedly not to do is actually a table of contents of what Jason is recommending we do do throughout the article…
Creatine (/ˈkriːətiːn/ or /ˈkriːətɪn/[1] is an organic compound with the nominal formula (H2N)(HN)CN(CH3)CH2CO2H. This species exists in various modifications (tautomers) in solution. Creatine is found in vertebrates where it facilitates recycling of adenosine triphosphate (ATP), the energy currency of the cell, primarily in muscle and brain tissue. Recycling is achieved by converting adenosine diphosphate (ADP) back to ATP via donation of phosphate groups. Creatine also acts as a buffer.[2]

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.
Weight training also requires the use of 'good form', performing the movements with the appropriate muscle group, and not transferring the weight to different body parts in order to move greater weight (called 'cheating'). Failure to use good form during a training set can result in injury or a failure to meet training goals; since the desired muscle group is not challenged sufficiently, the threshold of overload is never reached and the muscle does not gain in strength. At a particularly advanced level; however, "cheating" can be used to break through strength plateaus and encourage neurological and muscular adaptation.

When it comes to building muscle, your body only knows or cares about the tension, fatigue and damage an exercise is generating… not the type of equipment you were using when performing that exercise. It really couldn’t give the slightest crap about that. For this reason, ALL types of exercises and ALL types of equipment are capable of stimulating muscle growth.
While seasoned lifters may choose to do different exercises every day during a week-long period (and repeat the same moves the following week), there's no need to follow this type of program when you're just getting comfortable, says Davis. "Stick to the same basic moves two to three times a week to build a basic level of fitness and strength," says Davis. "Why complicate things if you don’t have to? Great results can be made by repeating the same workout but increasing weights as you become stronger." Switching things up can help you avoid a training plateau, explains Davis, but so can increasing weights while doing the same exercises.
Creatine supplementation has once been noted to improve wellbeing and fatigue resistance in people with DM2, but has twice failed for people with DM1. In all three studies, it has failed to improve power output. This is thought to be due to a reduction in the expression of the creatine transporter preventing an increase in muscular phosphocreatine content.
Now that you've got the training part down, it's time to stretch it out. (Can you say ahhh?) Stretching while your muscles are warm can help improve your flexibility, says Davis, not to mention it just feels phenomenal after you've pushed yourself hard. A light cool-down is also great for calming the nervous system. While dynamic stretches should be your go-to during a warm-up, the cool-down is where static stretching comes in—this means holding a stretch for 20-30 seconds. These four passive stretches will do nicely.

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]


Some other cytokines and hormones may increase the receptor activity. These include growth hormone (GH) which acts upon the growth hormone receptor (GHR)[166][167] to stimulate c-Src[168][169] which directly increases the activity of the CrT via phosphorylation. This is known to occur with the 55kDa version of c-Src but not the 70kDa version and requires CD59 alongside c-Src.[170]
The first U.S. Women's National Physique Championship, promoted by Henry McGhee and held in Canton, Ohio in 1978, is generally regarded as the first true female bodybuilding contest—that is, the first contest where the entrants were judged solely on muscularity.[13] In 1980, the first Ms. Olympia (initially known as the "Miss" Olympia), the most prestigious contest for professionals, was held. The first winner was Rachel McLish, who had also won the NPC's USA Championship earlier in the year. The contest was a major turning point for female bodybuilding. McLish inspired many future competitors to start training and competing. In 1985, a movie called Pumping Iron II: The Women was released. It documented the preparation of several women for the 1983 Caesars Palace World Cup Championship. Competitors prominently featured in the film were Kris Alexander, Lori Bowen, Lydia Cheng, Carla Dunlap, Bev Francis, and McLish. At the time, Francis was actually a powerlifter, though she soon made a successful transition to bodybuilding, becoming one of the leading competitors of the late 1980s and early 1990s.
In the stomach, creatine can degrade by about 13% due to the digestive hormone pepsin, as assessed by simulated digestion.[127] Although creatinine is a known byproduct of creatine degradation, simulated gastric digestion did not increase creatinine levels, indicating that other breakdown products were formed. However, creatinine was noted to increase in the presence of pancreatin, a mixture of pancreatic enzymes.[127] 
Longer rest periods are more ideal for making progressive tension overload happen, and shorter rest periods are more ideal for generating metabolic fatigue. So, if you’re doing an exercise that is better suited for progressive overload (i.e. primary compound exercises), you’re going to want to rest longer between sets to maximize strength output. And if you’re doing an exercise that is better suited for metabolic fatigue (i.e. isolation exercises), you’re going to want to rest less between sets to make that happen. And if you’re doing an exercise that is suited equally for a combination of the two (i.e. secondary compound exercises), you’re usually going to want a moderate rest period somewhere in between.
That means it takes time for supplements aimed at joint treatment to work. So plan not to feel anything for about two months after you start using glucosamine. After that, pain control with the supplement is comparable to what happens with drug use, according to various studies. The typical doses are 1,200 milligrams daily of glucosamine and 800 of chondroitin, which can be doubled initially.
A commercially available pre-workout formula comprised of 2.05 g of caffeine, taurine and glucuronolactone, 7.9 g of L-leucine, L-valine, L-arginine and L-glutamine, 5 g of di-creatine citrate and 2.5 g of β-alanine mixed with 500 ml of water taken 10 minutes prior to exercise has been shown to enhance time to exhaustion during moderate intensity endurance exercise and to increase feelings of focus, energy and reduce subjective feelings of fatigue before and during endurance exercise due to a synergistic effect of the before mentioned ingredients [72]. The role of creatine in this formulation is to provide a neuroprotective function by enhancing the energy metabolism in the brain tissue, promoting antioxidant activities, improving cerebral vasculation and protecting the brain from hyperosmotic shock by acting as a brain cell osmolyte. Creatine can provide other neuroprotective benefits through stabilisation of mitochondrial membranes, stimulation of glutamate uptake into synaptic vesicles and balance of intracellular calcium homeostasis [72].
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.
As mentioned, protein is essential for building muscle. If you are unable to consume the recommended amount of protein through diet alone, add protein powder for building muscle as a supplement. This applies to nearly anyone hoping to gain muscle mass since it’s not easy to pack in nearly 100 grams of protein a day through chicken, eggs and legumes alone.
There you have it — our five favorite creatine products on the market.

If you decide to join a gym, know that you're not expected to know how all of the equipment works right off the bat—or what to do with it. Be sure to take advantage of the free orientation so you can learn how to properly use everything that's offered and set up a basic strength-training program. At the gym, machines are preferred for beginners, because they're quite safe: Most require little coordination and offer more stability than free weights while performing the movements. 
After a tough sweat, it's important to rehydrate your body: "Drink lots of water and thank your body for what it was just able to accomplish," says Davis. A balanced post-workout snack is also a good idea. Go for one with carbs refuel your glycogen stores (one of your body's main energy sources) and about 10 to 20 grams of protein to help build and repair your muscles. "Don’t overcomplicate it," says Davis. If you're lifting and weight loss is one of your goals, though, it's still important to keep calories in mind—a post-workout snack shouldn't be more than 150 to 200 calories. Here's a guide to how many calories you should be eating for weight loss.

Researchers found that 5g of creatine four times daily for a week (loading) before sleep deprivation for 12-36 hours was able to preserve cognition during complex tasks of executive function at 36 hours only, without significant influence on immediate recall or mood.[279] A similar protocol replicated the failure to improve memory and attention, but noted less reports of fatigue (24 hours) and less decline of vigor (24 hours) although other mood parameters were not measured.[276]
Fish oils are an excellent source of omega-3 fatty acids, which provide myriad benefits for the body. For strength athletes and bodybuilders, we're most concerned with their anti-inflammatory and antioxidant properties. Intense resistance training can cause microscopic tears in your muscle fibers, leading to muscle damage and inflammation. While some inflammation is desirable, too much can delay the post-exercise recovery process.

This period also saw the rise of anabolic steroids in bodybuilding and many other sports. In bodybuilding lore, this is partly attributed to the rise of "mass monsters", beginning with Arnold Schwarzenegger, Sergio Oliva, and Lou Ferrigno in the late 1960s and early 1970s, and continuing through the 1980s with Lee Haney, the 1990s with Dorian Yates, Ronnie Coleman, and Markus Rühl, and up to the present day. Bodybuilders such as Greg Kovacs attained mass and size never seen previously but were not successful at the pro level. Others were renowned for their spectacular development of a particular body part, like Tom Platz or Paul Demayo for the leg muscles. At the time of shooting Pumping Iron, Schwarzenegger (while never admitting to steroid use until long after his retirement) said that "you have to do anything you can to get the advantage in competition".[citation needed] He would later say that he does not regret using anything.[8]


Although creatine is a natural component of food, the amount of food required to supersaturate the muscle with PCr may not be feasible. For example, it could require 22 pounds of meat daily [8]. If creatine monohydrate is proven to be a safe and effective ergogenic aid, creatine supplementation may be the simplest way to increasing muscle stores. It may be beneficial to avoid caffeine if taking creatine supplements. One study showed that caffeine diminished strength gains seen with creatine use [9].

It’s true—your genes can play a role when it comes to building muscle. In general, there are two types of muscle fibers: Type I, which are slow twitch, and Type II, which are fast twitch. Depending on which you have more of, you may have an easier or harder time gaining muscle. “Fast twitch muscle fibers are two times as thick as slow twitch muscle fibers, lending to the overall thickness of the muscle without any activity,” explains Lovitt. “Those people with a genetic predisposition of a high percentage of these fibers can increase muscle size very easily while the people with a higher percentage of slow twitch muscle fibers have to work really hard to put on mass.” It’s the reason why a world-class sprinter genetically has more fast twitch muscle fibers than a world-class marathoner—it comes down to what we’re born with.
Creatine has been investigated for its effects on depression, due to the significant changes occurring in brain morphology and neuronal structure associated with depression[246] and low brain bioenergetic turnover in depression[247], perhaps related to abnormal mitochondrial functioning, which reduces available energy for the brain.[248][249] The general association of low or otherwise impaired phosphate energy systems (of which creatine forms the energetic basis of) with depression, has been noted previously.[250][247][251] Due to associations with cellular death and impaired bioenergetics with depression, creatine was subsequently investigated.
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]
All you need to know about low creatinine levels Creatinine is a waste material in the body, and low levels can suggest a shortfall in liver function or activity. This MNT Knowledge Center feature looks at low creatinine levels., as well as information on what creatinine is, how it affects the body, and how to increase low creatinine levels. Read now
The reasons for differences in the effect of creatine on testosterone vs. DHT across studies are not clear, but also not mutually exclusive. A measured increase in DHT could indicate that testosterone levels were increased by creatine, but rapidly converted to DHT through a homeostatic mechanism. Differences in study subject populations, methodology, or the presence and type of concurrent exercise could also be contributing factors. At any rate, the literature collectively suggests that creatine has the general ability to cause a modest increase in androgen levels in men.
When it comes to finding the right meal plan, you have to start somewhere. Start with writing down what you eat in a food diary, calculate the calories you’re consuming daily (ex: 3,000 without protein shakes), and break those up into six meals (ex: 500 calories each), says Heath. Then, choose a macronutrient ratio. For example, the 40% protein, 40% carbs, 20% fat ratio is what Heath used to get bigger when he first started bodybuilding. “Buy a food scale, learn how to use it, and you may even have to learn to use the metric system, like grams instead of ounces,” Heath says. “You need to train your body to process food quickly, so eat every three hours.”
According to the abstract, in the stratified analyses by forms of aerobic exercise, weekly resistance exercise of 1 time or 1-59 minutes was associated with lower risks of total cardiovascular events and cardiovascular disease, regardless of meeting the aerobic exercise guidelines. The analysis showed that resistance training reduced the risk of cardiovascular events in 2 ways: training had a direct association with cardiovascular risk, and resistance training indirectly lowered cardiovascular risk by decreasing body mass index.
