How Does Exercise Affect Testosterone Levels?

Testosterone is the primary sex hormone for men. However, women also need testosterone. In men, testosterone is essential for:

• The formation of the penis and testicles
• Deepening of the voice
• Facial hair and balding
• Pubic hair
• Muscle development and size
• Bone strength
• Libido
• Sperm

Often, too much testosterone results in a bevy of symptoms such as:

• Reduced libido and fertility
• Risk of heart attack
• Acne
• Insomnia
• Increased muscles
• Headaches
• Aggressive behavior
• Mood swings

Too little testosterone in men leads to hair loss, muscle loss, hot flashes, increased breast size, and other symptoms. It’s important to understand that having a balanced level of testosterone is more important for your health than simply having more or less of it.

For women, testosterone is essential for:

• The ovaries and their health
• Bone density
• Libido

In women, there is less testosterone, but it must be balanced with other hormones. Thus, testosterone actually plays a significant role in the health and functioning of the ovaries. It is also intensely linked to mood, libido, and cognitive (mental) function.

Too much testosterone in women most commonly results in polycystic ovary syndrome or PCOS. The symptoms of PCOS are usually:

• Irregular menstruation
• Lessened fertility
• Abnormal hair growth on the face, extremities, and other parts of the body
• Thick skin
• Weight gain
• Depression
• Anxiety

However, there is still a lot we are still learning about testosterone and its role in women’s bodies.

Over a long period of time, exercise has been found to increase testosterone levels in men. However, even over the short term, exercise has been found to have effects. Some exercises more than others have been found to increase testosterone levels within fifteen minutes and an hour of doing them.

This short-time spike disappears after that period of time and is bigger for younger men. Additionally, testosterone levels are naturally higher in the morning and lower in the afternoon. So if you work out in the morning and do specific workouts that heighten your testosterone levels, you will get a short-term boost. However, only regular exercise over time will raise your testosterone levels in the long term.

Currently, there is no evidence that testosterone levels increase when women exercise. However, an increased presence of testosterone in a woman’s body during exercise helps women to train. In addition, testosterone helps muscles recover faster, which benefits overall exercise progress.

Here are some of the exercises that have been found to temporarily boost your testosterone:

• Weightlifting. This practice is said to be one that is most linked to higher testosterone levels. Its muscle-boosting effects are thought to generate more testosterone. If your focus is increased testosterone, it's best to target larger muscle groups while you are lifting. However, strengthening your whole body helps your metabolism and aids you in avoiding injury. So, don’t ignore other parts of your body in your quest for more testosterone.
• High-intensity interval training. This is a type of exercise in which you usually complete short but intense periods of activity that substantially increase heart rate. Intense periods are followed by periods of recovery that are about the same length of time or a little shorter than the exercise periods. The entire workout should last around twenty minutes to an hour.

Marathon running, cycling, or other types of long-distance exercises designed to test your endurance have been found to lower your testosterone levels over time. This reduction could be partially due to the way that endurance exercises break down your muscles.

You may combat this reduction in a variety of ways that safely and naturally boost your testosterone levels, including:

• Eating a healthy and balanced diet
• Stress management
• Getting enough vitamin D either through the sun or supplementation
• Practicing proper sleep hygiene
