If you’re a healthy guy in your 30s and 40s, your testosterone will be declining—but that doesn’t mean you actually need treatment. “If you go in and say, ‘Well, you know, in the past 10 years I’ve gotten more tired, I’m having trouble keeping weight off…’ that’s simply not enough—it’s a natural phenomenon!” Jacques Baillargeon, ., an epidemiologist at the University of Texas Medical Branch at Galveston, told Men’s Fitness. However, if you’re a man north of 50, and you’re having difficulty getting it up, you’re feeling depressed, and you’re generally unhappy, you should seek out TRT.
“In general, all types of exercise stimulate the release and production of testosterone,” says sports medicine doctor Jordan Metzl, ., author of The Exercise Cure . “But there is data to suggest that lifting weights and high-intensity work might stimulate the greatest release of testosterone.” While research shows that those post-workout super-spikes may be temporary, the overall boosting benefit of regular exercise can’t be ignored. Pretty much any and all resistance work is worthy of a place in your T-tweaking program; on the other hand, long, slow cardio slogs, such as everlasting jogging sessions, may have a negative effect on testosterone levels.
