Fitness & physical performance

Train with your hormones, not against them. We cover strength, hypertrophy, VO2 max, recovery, and injury prevention through an endocrine lens. Discover how training, nutrition, and daily activity can impact testosterone levels and support natural balance. Use estradiol balance for joint health, plan sleep taper cycles before competitions, and turn smart physiology into new PRs.

The best weight loss supplements for men are the ones with human evidence, modest expectations, and a clear mechanism — and green tea extract is one of the few that consistently shows a signal in research. This guide breaks down what “works” really means, how to use supplements safely, and what numbers to track so ...

Keto diet and CGM: What your glucose level can look like and how to avoid reverse metabolic inflexibility

Keto diet and CGM: What your glucose level can look like and how to avoid reverse metabolic inflexibility

On a ketogenic diet, CGM traces usually show a lower, flatter 24‑hour glucose curve, while a rare high‑carb meal can cause a higher peak and slower return to baseline because fat adaptation temporarily downshifts rapid glucose disposal (“reverse metabolic inflexibility”) rather than proving true insulin resistance. Learn how to interpret trends despite interstitial‑fluid lag and ...

Bryan Johnson’s commercial “Blueprint Stack” promises a simplified route into a longevity-focused routine. This blueprint stack review breaks down what’s actually in the stack as described, what the research says about the major components for men, and how to use a “stack” approach without drifting into expensive guesswork. “If a ‘stack’ helps you consistently hit ...

Building muscle after 40: The science of getting stronger when recovery slows down

Men over 40 can still build muscle and strength, but anabolic resistance and slower tissue repair often extend recovery from heavy sessions to roughly 48–72 hours, meaning the hypertrophy stimulus has to be higher to meaningfully trigger muscle protein synthesis. Here’s how to adjust training volume and target 30–40 g of high‑quality protein (~3–4 g ...

Bulking and cutting work by deliberately shifting energy balance: a 250–500 calorie daily surplus supports muscle protein synthesis and hypertrophy, while a sustained calorie deficit drives fat oxidation but can increase muscle protein breakdown. The key to body recomposition is committing to one clear signal for 12–16 weeks—rather than chasing muscle gain and leanness at ...
