Testosterone (“T”) is the so-called “He Hormone” even though it’s produced in the bodies of both men and women. Men produce more of it, which is why, on average, dudes have bushier beards and deeper voices than Kim Kardashian or Taylor Swift. Men’s T levels peak during our teen and early adult years, then decrease about 1% a year after age 30. But beyond normal aging, there’s a mysterious generational decline going on. Let’s start with the numbers. Research published in the Journal of Clinical Endocrinology & Metabolism spanning three decades found that when the T levels of same-aged American men were compared, the men of the 1980s had higher average T levels than the men of the ‘90s, and the men of the new century have on average the least T of all.1 For example, a 60-year-old man in 2004 had T levels 17% lower than those of a 60-year-old in 1987. Another study of Danish men produced similar findings, with men born in the 1960s having 14% lower T than those born in the 1920s.2 Lower T is associated with lower sperm counts, raising concern for the next generation. A 2017 study found that average sperm counts in Western countries had nosedived by 59% between 1973 and 2011, making low T and plummeting sperm counts a major public health issue.3
Why are average T levels dropping in recent generations? In my book Alpha Male Challenge,4 coauthored by James Villepigue with an esteemed group of expert contributors, we cited the usual suspects: poor diet, lack of exercise, less demanding physical labor, more obesity, ingestion of phytoestrogens, and exposure to various environmental toxins (including endocrine disruptors like parabens and phthalates). Surely, all are possible culprits (see sidebar for 5 suggestions on naturally boosting your T).

Best Cardio for Fat Loss - High Intensity vs. Low Intensity
Low-intensity cardiovascular exercise is the most common way to reduce body fat, despite mounting scientific evidence showing this form of cardiovascular training may not burn body fat as effectively as high-intensity cardio. In addition, low-intensity cardio has also been shown to inhibit muscle growth¹2, making the use of this approach to enhance your physique even more questionable.
Are Unilateral Exercises More Effective Than Bilateral Exercises?
Bilateral exercises simultaneously use both limbs to lift the weight, so that the resistance is being shared between each limb.

BRYAN JONES: THE LORD OF CLASSIC RETURNS!
It seems like a decade has passed since the pandemic began in 2020. That was a chaotic year for all of us. MD sent me to Atlanta to cover the Chicago Pro, because restrictions in Illinois made it impossible to hold Tim Gardner's annual extravaganza there. The athletes still showed up in force to compete, and the Classic Physique division alone featured 30 men. When they came out to be adjudicated, one man stood out in a flash as the one to beat. I had never heard of Bryan Jones until that point aside from a vague recollection that he'd won the USA a couple of years before. With his braided and colored hair piled on top of his head in a gathered bun with the ends appearing to be some type of bizarre plant, I dubbed him \"The Kai Greene of Classic.\" That didn't stick, thankfully, because Bryan \"Lord\" Jones is a unique athlete in his own right. I knew I was looking at a man who was going to make waves in that division. A few months later he did just that, placing fifth in his first Olympia appearance. But we only saw him twice more after that, at the Arnold Classic and once again at the Olympia at the end of 2021. Since then, Jones has been working hard to build the additional size needed to successfully transition to the Open category. I spoke with him about his brief but notable time in Classic, and how he plans to make a big splash in Open.

HOW MUCH REST IS BEST?
Getting enough rest after weight training is essential for optimal muscle growth and performance. Unfortunately, many get insufficient rest because they simply disregard the fact that weightlifting breaks down muscle tissue, creating the requirement for adequate rest to fully recuperate.
Get Peeled With Extra Virgin Olive Oil
As you know, pathologic fat accretion results in obesity. The medical community and pharmaceutical industry have been struggling to address this burgeoning condition in the Western culture - particularly in the United States. Obviously, individuals have also been struggling in their attempts to avoid or correct unsightly or unhealthy fat gain. Imagine the shame these professionals and people must feel when they realize they may have been ignoring a risk-free, health-promoting, inexpensive dietary ingredient that can enhance fat loss. Bodybuilders seek potent drugs or supplements to force the metabolism to strip body fat to low single-digit percentages, but failing to acknowledge the foundation of diet can sabotage even their extreme measures.
CREATINE: THE BEST FORMS
New products and formulations are introduced to the supplement market every day. However, it is very rare for a product or especially an ingredient to create noteworthy evolution in supplement performance. Arguably, the greatest leap up this axiomatic evolutionary ladder occurred with the advent of creatine supplements in the 1990s. Creatine has proven over and over to be \"the real deal\" in clinical research and broscience. It's a muscle-building, performance-enhancing supplement that nearly all athletes should use.
