This is due to improved receptor sensitivity and hormonal balance, further boosting muscle mass and strength. This routine helps the body adapt, leading to long-term improvements in testosterone response. For example, research explains that testosterone promotes muscle growth by stimulating protein synthesis and inhibiting protein degradation. The more muscle you have, the more your body is encouraged to make testosterone, creating a positive feedback loop. Once testosterone binds to androgen receptors in your muscles, it triggers a process that makes it easier to add lean muscle mass. These habits affect the body's ability to produce and regulate hormones effectively. According to the American Urological Association, total testosterone levels below 300 ng/dL fall into this category.
Here’s a look at how your workouts affect testosterone levels, what the science says, and how to build your training around evidence rather than gym lore. Additionally, the confidence gained from increased muscle mass and strength can improve self-esteem, contributing to better sexual health. In fact, testosterone is considered one of the major promoters of muscle growth in response to endurance training. The body works in an anabolic (muscle-building) environment when testosterone levels are in a good range. Choosing the right exercises for resistance training is key to boosting testosterone.
While the connection between physical activity and muscle growth is widely recognized, the hormonal cascade triggered by exercise extends far beyond aesthetics. Healthy testosterone levels are crucial for overall well-being. Fatigue is a common symptom of low testosterone because muscles lack sufficient testosterone to process energy in the body. Men diagnosed with hypogonadism from a blood test need testosterone replacement therapy (TRT) to supplement the body’s natural production of this hormone. Experts believe that since cortisol is low, the testosterone released in response to exercise is more effective.
Are there any natural ways to boost testosterone without supplements? But individual responses vary considerably. Testosterone can affect mood and energy levels. While testosterone plays a role in regulating metabolism, testosterone boosters are not primarily weight loss supplements.
For trained athletes, low-intensity endurance training won’t increase testosterone—if you’re overtraining or not taking in enough calories to fuel your workouts, it can actually suppress testosterone levels. Interestingly, the resistance training styles most effective for building muscle—big lifts, high volume, short rests—also produce the strongest hormonal responses, including testosterone.7 In men who are already active, lean, and have a normal testosterone level for their age, exercise can boost how efficiently their muscles use testosterone—and help with hypertrophy (muscle growth), but it probably won’t raise their baseline testosterone levels. Lasting increases in baseline testosterone levels generally happen only if exercise leads to significant improvements in inflammation markers and body composition—like reduced body fat—in men starting out with low testosterone. After a workout, especially resistance exercise or HITT, testosterone surges and then fades rapidly (within 15 to 60 minutes).6 This is your body’s acute response to physical stress and helps jumpstart muscle repair. Endurance training and resistance training (such as weight lifting) both boost testosterone levels briefly, Schroeder says. For some men, resistance training alone may not be enough to address low testosterone levels.
One study following men with obesity found that regular exercise increased testosterone levels more directly than weight loss alone.16 While strength training is the most widely confirmed form of exercise for increasing testosterone, there is some evidence linking other workouts to higher testosterone. Doing multiple reps and sets with relatively heavy weight burns through energy stores, builds up lactate, and increases blood flow—all of which are linked to short-term spikes in hormones like testosterone and growth hormone.12
The more body fat you carry, the more testosterone you convert to estrogen, reducing your effective testosterone level. Excessive volume and frequency without adequate recovery leads to overtraining, which suppresses testosterone through elevated cortisol. Heavy compound movements performed to near failure produce the most significant acute testosterone response. The clients who make the biggest testosterone gains from lifestyle optimization alone are almost always the ones who were sleeping poorly. The protocol for testosterone-optimized sleep is specific. Yet sleep is consistently the most neglected factor by men who spend hundreds of dollars on testosterone boosters. One week of sleeping five hours per night instead of eight drops testosterone by 10 to 15 percent.
They also help lower cortisol, which is good for your muscles4. These exercises should be done at a moderate level of intensity. Getting a blood test is the best way to check if your testosterone is normal for your age2.
