That said, not all weight-training protocols are as effective at inducing an increase in anabolic hormone levels – suggesting that the increase in anabolic hormone from weight training is dependent on factors associated with training program variables such as exercise intensity and training volume, as well as the type of training equipment used such as free weights or exercise machines. While many studies have investigated the influence of such variables as training intensity and volume on the anabolic hormone response, only recently has the hormonal response to free weights and machine exercise training been compared, showing a considerable difference between these two training modalities.
Anabolic Hormone Levels
Because the apparent discrepancy between free weights and machines on the anabolic hormone response to training had been unexamined, Shaner et al. investigated the effect of a similar free-weight movement (squat) and machine exercise (leg press) on anabolic hormone response. In this study, 10 young men with weight training experience completed six sets of 10 repetitions of squats or leg presses at the same relative intensity one week apart. After each exercise session, blood samples were analyzed for testosterone, GH, and cortisol concentrations. The results of the study by Shaner et al. showed that testosterone levels were considerably higher after performing the squat when compared to the leg press. The authors suggest that this difference may be due to the greater amount of muscle mass recruited during the squat8 that has clearly been shown to be an important factor that enhances testosterone production. In addition, while GH concentrations were elevated after the squat and leg press, the increase was much greater after performing the squat. Because lactate production has been shown to trigger GH secretion10, the authors propose that the larger increase in GH from squatting is also likely due to the greater amount of activated muscle mass, which generates more lactate and triggers more GH release.

TESTOSTERONE AND HAIR LOSS: How to Get Ahead
The simple fact is that most men are concerned about their looks; for the bodybuilder and fitness enthusiast, appearance is a strong factor in one’s satisfaction. It is undeniable that testosterone (T) directly impacts the physical health, function, and appearance of a man; as well, one’s mental health and cognitive abilities. In the chronology of life, testosterone’s effects produce milestones that easily identify the stages of life: the ultrasound’s shadow of a penis during pregnancy; a wispy mustache during adolescence; a deep voice during adulthood; and with its decline late in life, the loss of muscle, and erectile dysfunction.
TESTOSTERONE AND GH RESPONSES: FREE WEIGHTS VS. MACHINES
All forms of resistance training provide a stimulus that induces an anabolic-hormonal response, which contributes to adaptations associated with weight training such as muscle growth and strength. More precisely, weight training causes an increase in the two most prominent muscle-building hormones, testosterone and growth hormone (GH). Testosterone drives muscle growth by stimulating muscle protein synthesis and inhibiting muscle protein degradation. GH triggers greater muscle growth primarily by stimulating the production of insulin-like growth factor 1 (IGF-1), which has been shown to also potently stimulate muscle growth by increasing muscle cell protein synthesis.

NEW RESEARCH: INTERMITTENT FASTING INCREASES AB FAT
Intermittent fasting, often referred to time-restricted eating, has become the latest diet craze not only for weight loss but also for enhancing health. Everyone from well-known celebrities to everyday, average people are trying intermittent fasting and claiming it is successful.
Lose Fat and Boost TESTOSTREONE
Every bodybuilder or athlete understands too much body fat can be detrimental. For the bodybuilder, too much body fat detracts from the physique. The athlete can’t carry too much body fat because it decreases speed and quickness, thus diminishing athletic performance. Although fat tissue can be physically unappealing to the bodybuilder while negatively influencing athletic prowess, fat cells also perform an additional function that can negatively impact the athlete and bodybuilder by drastically decreasing the production of the muscle-building hormone testosterone.
Lorie Forman LOOKING Great at 48!
Lorie Forman turned pro as a Bikini competitor at the 2015 NPC Universe, and was the first woman to score three pro card wins in one show and in every division she entered: Bikini Open, Masters Over 35 and Masters Over 40 and took home the Masters overall. But that’s not Lorie’s only remarkable achievement: at age 48, she looks and feels like a twenty-something athlete.
BRAD ROWE IFBB Pro and Trainer to the Stars!
Success in bodybuilding is often assumed to correlate with contest wins and high finishes at the Mr. Olympia and Arnold Classic. Yet there are many other avenues available today, some far more lucrative than relying on prize money or even supplement contracts. One man who exemplifies the level of success possible beyond the stage is Brad Rowe. Though he was no slouch on stage, he gained far more visibility appearing in national commercials for companies like GoDaddy, Coca-Cola, Kia, Taco Bell and Dannon Oikos, some of which aired during Super Bowls. More recently, Brad’s prominence as an elite personal trainer got a major boost when Mike Tyson hired him to be his full-time strength and conditioning coach, training him for his 2020 comeback fight at age 54 with Roy Jones Jr. I spoke with fellow native New Englander Brad about why he stepped away from competing, how he became part of Mike Tyson’s training camp, and his major project that stands to make him one of the biggest players in the growing field of anti-aging and cutting-edge athletic performance.

A Tribute to THE INCREDIBLE ANDY HAMAN
In my 35 years as Publisher and Editor-in-Chief of Muscular Development, I never met a guy like Andy Haman. We had one thing in common, we both wrestled in college. I went to Indiana State University on a wrestling scholarship and Andy went to the University of Iowa and became a championship wrestler. In 2007, Andy won the super heavyweight class at the NPC Masters bodybuilding championships, earning his pro card.
