As a human being, your body is subjected to a lot of stresses during the course of a day and night. This coupled up with the aging process can take its toll on important chemical processes that are vital for daily functioning. One of these would be testosterone release. Testosterone is a hormone known for its ability to increase libido and muscle mass. Instead of being subjected to applications that come equipped with harmful side effects, there are some natural ways of increasing this hormone that can be just as effective.
Turn up the volume in your cardio workouts. Don't get me wrong, walking is great exercise. But try doing some sprint intervals to really amp up testosterone release. Run then walk, or run, take a break double the length of your sprint, then repeat for 8 to 10 reps. It might be hard to get used to at first, but you'll catch on in no time.
Do active recovery when lifting weights. Weight lifting is already known for its hormone releasing potential, but in order to really get the maximum benefit, try turning up the intensity. One way of deploying this is by doing active recovery in between sets. It doesn't have to be fancy or pretty. You can do jump ropes, step-ups, seated balances, box jumps, jogging around the gym floor or power skips. The only thing that matters is you like it and it keeps your heart rate up.
Take shorter rest periods. This philosophy can apply to weight training and cardiovascular training. It's pretty self explanatory. Whether you are doing sprint training or you are lifting weights, gradually reduce your rest periods.
Eat foods that are high in zinc. It has been known that zinc is a good inducer of testosterone release. Some of these foods would include red meat, oysters, whole grains, beans, milk and cottage cheese. Just be cautious of the fat intake and what additives and preservatives might have been used.
Get enough sleep. This is probably the number one reason for compromised testosterone levels. Your body utilizes sleep as a time for repair and recovery. This is done through the release of a lot of key hormones. If you deprive yourself of sleep, then you are depriving yourself of the adequate recovery you deserve from those hard workouts in the gym and on the trail.
