Boron at 6 to 10mg daily has been shown to increase free testosterone by reducing SHBG and lowering estrogen. Magnesium supports testosterone both by lowering SHBG and by improving sleep quality. The testosterone-optimal body fat range for most men is 12 to 18 percent. Losing excess body fat directly improves your testosterone to estrogen ratio by reducing aromatase activity.
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.
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.
Research shows that these workouts can greatly increase testosterone levels right after exercise4. In short, knowing how testosterone works with exercise and muscle growth is key for better workouts and health. Exercise may also play a role in your testosterone levels—which effects muscle growth. In summary, testosterone is an important modulator of muscle mass in both men and women and acute increases in testosterone can be induced by resistance exercise. For example, research has found that men who performed resistance training several times per week experienced increases in testosterone immediately after workouts and improvements over time. Over time, consistent resistance training also supports muscle growth and strength gains. Resistance training, such as weightlifting or body weight strength exercises, is one of the most reliable ways to increase testosterone temporarily.
This means doing exercises that work your muscles hard and often. Resistance training can really boost testosterone in men. By understanding how testosterone works, you can make your workouts more effective and use natural boosters to your advantage.
Many studies have explored this, showing how different workouts affect hormone levels. Remember, too, that your testosterone levels naturally fluctuate during the day. While there’s research on the subject, McNeil says yoga and pilates, which incorporate aspects of strength training, likely have a positive impact on testosterone. Don’t worry so much about just focusing on resistance training because you think it raises your T.
Weightlifting to influence testosterone levels should be challenging enough to build muscle, which means lifting heavy enough to complete 5 to 12 quality repetitions per set. More optimal testosterone then directly improves metabolic health, making it easier to maintain a healthy bodyweight. While it’s true that testosterone plays a major role in muscle growth and training results, it’s not the whole story. He says the following strategies will give you an even bigger boost in testosterone from your strength training workouts, which is backed up by research. Lifting weights or doing other strength-training workouts has a bigger effect on your testosterone, Schroeder says.
This increase can contribute to improved muscle mass, bone density, and libido. Chronic stress can significantly lower testosterone levels by elevating cortisol, which interferes with testosterone production. Focus on a balanced diet rich in protein, healthy fats, and micronutrients to support natural testosterone production. How long does it take to see an increase in testosterone from exercise? Testosterone levels naturally decline with age, and individual responses to exercise can differ significantly.
