Increasing testosterone through exercise is quite possible. Moderate exercise, aerobic or weight lifting, will have the effect of boosting testosterone levels. Moderate means 45 minutes to one hour maximum.
Continued exercising after one hour may cause a DECREASE in testosterone. Some believe that testosterone levels after a leg workout will be particularly low, but there is no evidence supporting this, unless the leg workout continues for more than one hour.
Because most workout routines are measured in sets and reps, not minutes and hours, it is necessary to either keep an eye on the clock and stop after one hour, or add a testosterone boosting supplement, like Tribulus Terrestris
Studies of Bulgarian Olympic athletes, whose work-outs are considerably more than one hour, showed that testosterone levels increased by as much as 40% in those athletes using tribulus. Tribulus is not a steroid, but an herb.
There are other herbs and supplements that, after regular use, also result in boosting testosterone levels.
The idea that testosterone levels after a leg workout are lower than after other exercise, may stem from the study showing decreased testosterone production in endurance trained athletes.
Mostly runners, who had been training for 1-15 years, were studied to determine the effects of endurance training on the reproductive system. The results showed testosterone levels up to 85% lower in the endurance-trained men when compared to men of the same age who were not endurance trained.
So, if you have a goal of increasing testosterone through exercise, avoid endurance training.
If you are already an endurance trainer, boosting testosterone may require some form of supplementation.
One study related to boosting testosterone and exercise, showed that men who participated in moderate regular exercise programs experienced less Andropause symptoms
Another study of men who had been previously sedentary and began a regular fitness program experienced fewer andropause related symptoms.
Things to remember: There is no evidence showing that testosterone levels after a leg workout are any different than they are after any work-out.
Indeed, there is evidence that indicates that leg workouts that are high in intensity and short in duration, such as full out sprints, may help increase HGH (human growth hormone).
There is no need to delete these from your routine for the purpose of boosting testosterone levels. And, increasing testosterone through exercise is possible as long as the duration does not exceed one hour.
