1: Lose Weight
Obesity has been linked with lower-than-average testosterone levels. It can also exacerbate the existing symptoms of limited testosterone production, including depression, lethargy and decreased sex drives. To kick things back into gear, kick yourself off the couch.
2: Start Strength Training
The more you bulk up, the more you'll increase your testosterone. It's the body's natural response to creating muscle and optimizing your cardiovascular health. For even faster results, employ high-intensity exercises.
