In men with obesity (BMI over 30) and low testosterone, combining semaglutide with testosterone therapy can promote fat loss while helping preserve lean muscle by reducing adipose-driven aromatase conversion of testosterone to estradiol and supporting anabolic metabolism. Instead of treating weight and hormones as separate problems, this paired approach targets the feedback loop where visceral ...

Frequent masturbation does not meaningfully increase basal metabolic rate, or BMR, in men, and a typical session only burns a small number of calories. Masturbation typically burns about 15 to 40 kilocalories in 10 to 15 minutes, about 2 to 3 METs, closer to slow walking than a workout, so here is what the research ...

Henry Cavill’s “superhero” build (reportedly about 190 to 210 lb on screen) is achieved by combining high-mechanical-tension lifting to stimulate hypertrophy with metabolic work (including fasted cardio) that can support energy balance and lipid oxidation. Here’s how recovery, neuromuscular adaptation, and joint-protective programming make that body composition sustainable instead of short-lived “ego lifting.” “When we ...

Elliptical trainers provide low-impact, weight-bearing cardio that can improve aerobic fitness and help maintain or reduce body fat when programmed at sufficient intensity. Here is what they actually do to your muscles, joints, heart, and hormones, and how men can use them for real results. “When guys ask me what do elliptical trainers do, they ...

Most men burn roughly 200 to 600 calories in a 45 minute lifting session depending on body weight, the MET level of the workout (traditional lifting around 3.5 METs vs vigorous circuits around 8 METs), and how dense the session is (rest times and transitions). Compared with a steady cardio session of the same length, ...
