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.

Energy drinks without sucralose aren’t automatically healthier—their health impact is driven mainly by caffeine dose and total sugar, and most healthy adults should keep caffeine under about 400 mg per day from all sources. Here’s how to decode what’s used instead (like sugar or stevia) and read labels for gut, hormone, sleep, and long-term metabolic ...

Human clinical trials show tongkat ali can modestly improve testosterone—likely by lowering cortisol and SHBG—while fadogia agrestis has little to no robust human evidence and an unresolved side‑effect profile based mostly on animal data. The stack targets the HPG axis from two angles (tongkat “releases the brakes,” fadogia aims to boost LH), but the gap ...

A 100‑gram protein meal after resistance training can support muscle protein synthesis for longer rather than being “wasted,” because the body slows gastric emptying and releases amino acids into the bloodstream for roughly 12 hours (vs. a quicker rise-and-fall with 25 grams). That finding challenges the old 30‑grams‑per‑meal rule and reframes how to time bigger, ...

When total weekly volume is matched (about 10–20 hard sets per muscle group) and sets are taken close to failure, training each muscle once per week can produce similar hypertrophy to hitting it 2–3 times per week in most lifters. The catch is that cramming all that work into one session can degrade later-set quality ...

To add the internal link, I identified a highly relevant context in the “Myth vs Fact” section. The text debunks the myth that L-carnitine is a magic fat melter, emphasizing the need for calorie deficit and training for “meaningful fat loss.” This aligns perfectly with the target article “Do weight loss supplements work for men? ...
