Yes, you can pack on size while only doing bodyweight exercises – I did it while traveling the world – and gymnasts train mostly with bodyweight movements. However, this can feel like playing Halo on Legendary difficulty. It can be done, but damn it can be challenging – especially for lower body movements. If your sole goal is to get bigger as fast as possible, access to a barbell for squats and deadlift is almost a requirement.
Testosterone is used as a medication for the treatment of males with too little or no natural testosterone production, certain forms of breast cancer, and gender dysphoria in transgender men. This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range. Decline of testosterone production with age has led to interest in androgen replacement therapy. It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.
To do dips, place your hands at shoulder-width apart on a bench, with your body and feet stretched out in front of the bench. Slowly bend your elbows and lower your body down so that your butt nearly touches the floor. Lift back up with your arms to starting position; repeat, doing 3 x 8. If this isn't a high-intensity set for you, increase the resistance by lifting one foot off the floor.
Prohormones are precursors to hormones and are most typically sold to bodybuilders as a precursor to the natural hormone testosterone. This conversion requires naturally occurring enzymes in the body. Side effects are not uncommon, as prohormones can also convert further into DHT and estrogen. To deal with this, many supplements also have aromatase inhibitors and DHT blockers such as chrysin and 4-androstene-3,6,17-trione. To date most prohormone products have not been thoroughly studied, and the health effects of prolonged use are unknown. Although initially available over the counter, their purchase was made illegal without a prescription in the US in 2004, and they hold similar status in many other countries. They remain legal, however, in the United Kingdom and the wider European Union. Their use is prohibited by most sporting bodies.
In regard to bioenergetics, phosphorylated cyclocreatine appears to have less affinity for the creatine kinase enzyme than phosphorylated creatine in terms of donating the high energy phosphate group (about 160-fold less affinity) despite the process of receiving phosphorylation being similar. When fed to chickens, phosphorylated cyclocreatine can accumulate up to 60mM in skeletal muscle, which suggests a sequestering of phosphate groups before equilibrium is reached. Cyclocreatine still has the capacity to donate phosphate, however, as beta-adrenergic stimulated skeletal muscle (which depletes ATP and glycogen) exhibits an attenuation of glycogen depletion (indicative of preservation of ATP) with phosphocreatine.
Without supplementation, creatine is formed primarily in the liver, with minor contributions from the pancreas and kidneys. The two amino acids, glycine and arginine, combine via the enzyme Arginine:Glycine amidinotransferase (AGAT) to form ornithine and guanidoacetate. This is the first of two steps in creatine synthesis, and although rare, any deficiency of this enzyme can result in mild mental retardation and muscular weakness. AGAT is also the primary regulatory step, and an excess of dietary creatine can suppress activity of AGAT to reduce creatine synthesis by reducing AGAT mRNA levels, rather than resulting in competitive inhibition.
One study in elite swimmers subject to sprints (varying in length from 25-100m) failed to find benefit with creatine supplementation, although there was also a failure on leg extension strength, suggesting nonresponse. This has been noted twice elsewhere with a similar protocol, while one study in elite swimmers subject to single 50m or 100m sprints found benefit with supplementation and one found benefit with six repeated 50m sprints by 2%, yet not ten repeated 25m sprints with elite male swimmers (females failed to find benefit). Another study also noted benefits in elite swimmers on a sprinting protocol. Overall, the evidence is quite limited and suggests either a mild, or more likely, no increase for elite swimmers, although one study confirming an increase in body and water weight failed to find a decrement in performance.
In an article entitled Active Seniors Enjoy Life More, the American Council on Exercise reports, “As you grow older…regular exercise can help boost energy, maintain your independence, and manage symptoms of illness or pain. Exercise can even reverse some of the symptoms of aging.” Wow! Are you sold yet? But wait, there’s more. While taking your daily walk remains a crucial piece of this exercise pie, getting in your strength training reps is the part that will truly make the difference in your well-being. The Center for Disease Control and Prevention (“CDC”) recommends strength training for most older adults to help lessen the symptoms of the following chronic conditions:

Many people are looking for magic bullets in their efforts to fuel their bodies, sharpen their minds, and hold on to their youth. As a result, some spend a small fortune on novel dietary supplements, hoping that the promising results of studies exploring the effects of these compounds in other animals translate to humans. Unfortunately, however, this is rarely the case. But every now and then a supplement is proven to actually help lots of people. Creatine has been around for decades, so it’s easy to overlook it amidst hype over newer pills and powders. Yet I think it might be the most beneficial, underappreciated, and cost-effective supplement there is – if I could only recommend one supplement for everyone to take (an absurd scenario, I know), it would be creatine monohydrate. That’s a bold statement, so in this post I’ll support my stance. As a result, I hope that you too get to experience the diverse benefits of creatine supplementation.
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. 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. Researchers examining another case of MELAS found both cognitive and physical benefits with 5g creatine supplementation, 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.

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.
How to do it: Stand tall with a dumbbell in each hand, arms to your sides. Put some slack in your knees so they’re in a neutral position, slightly bent. Extend one leg back; this non-weight-bearing leg should extend straight back until it’s parallel to the floor, while your planted leg remains engaged and planted firmly to the floor. Your weight-bearing knee should be neutral to just slightly bent to avoid hyperextension. Sink your arms toward the floor when you draw your elevated leg back, moving with the flow of gravity. Use your glutes to pull yourself back to the upright position.
How to do it: Use just your bodyweight, dumbbells, or a resistance band around the top of your knee to activate your glute medius, Reames says. Assume the same setup of a basic squat, feet shoulder-width apart and knees neutral. Squat down, knees bent at 90° angles, and step to the side. Continue repeating this side-step motion down and return to your starting position.
Having a strong butt will get you far—literally. Our glutes are responsible for powering us through everything from long runs to tough strength workouts to a simple jaunt up a flight of stairs. Strong glutes that can take on the brunt of the work can help us avoid overcompensating with smaller muscles during lower-body exercises. Plus, beyond just helping us move, the glutes play an important role in "stabilizing our entire lumbo-pelvic-hip complex," says Cori Lefkowith, NASM-certified personal trainer and owner of Redefining Strength in Costa Mesa, California. That translates to better form, more efficient movement, and a reduced risk of straining your lower back and hips.
