How Exercise Really Affects Your Testosterone, According to Doctors

Working out regularly has a profound effect on all aspects of your health, including your heart and mental health. Exercise may also play a role in your testosterone levels—but exactly how it does that is a little complex.

‘Testosterone levels are affected by exercise but ongoing work is needed to really understand what is happening,’ says Edward Cherullo, M.D., chair of urology at Rush University Medical Center in Chicago.

What we do know so far is that the relationship between exercise and testosterone depends on several factors. One is the type of workout you choose, says Brian McNeil, M.D., chief of urology at SUNY Downstate Health Sciences University. Over time, strength and resistance training have been shown to increase testosterone levels while cardio might not have as much of an effect.

It also depends on how intensely you’re working out and for how long, explains Anthony Hackney, Ph.D., D.Sc., a professor of exercise physiology and nutrition at the University of North Carolina, who’s studied exercise and testosterone for decades.

Testosterone, the main male sex hormone that’s produced by the testicles, is anabolic and does help you build muscle, Hackney says. (That’s one of its functions, anyway; it has many others.) But other hormones also contribute to muscle building and endurance.

‘While testosterone is important, it’s not the only way the body decides to create an anabolic response,’ Hackney adds.

Exercise affects testosterone in other ways, too, Dr. McNeil adds. When you work out, you’ll improve your overall health and reduce your body fat, which he says can improve testosterone. Obesity is linked to low testosterone and other health problems.

‘All of these things put you in the best shape possible,’ he says. Here’s a closer look at how exercise affects your T levels.

Does Working Out Affect Testosterone Levels?

Exercise does impact testosterone levels, but research suggests that the actual effect depends on several factors.

‘Certain types of exercise done at certain volumes and intensity can lead to an elevation in testosterone, but you can also have certain types of exercise, certain volumes of intensity that can reduce testosterone,’ Hackney says. ‘So, there isn’t a universal, ‘Oh, I’m exercising, and I’m always going to see this testosterone response.”

Many studies looking at different types of exercises—including cardio, cycling, running, swimming, and weightlifting—and their effects on T levels have found different outcomes, explains Ahmed El-Zawahry, M.D., a urologist at the University of Toledo Medical Center.

‘If we are going to summarise the results of these studies in one easy statement, exercises do not significantly change testosterone level,’ he says.

Still, some exercises, especially weightlifting, can temporarily boost testosterone. But, Dr. El-Zawahry says the surge doesn’t last long.

Body composition and fitness level factor into how exercise affects your testosterone, too. A small 2016 study found that obese and overweight men saw a boost in their T levels when they increased their physical activity, more so than when they solely restricted calories.

A 2018 study suggested that some male elite athletes had low testosterone concentrations, but the low T may be linked to higher cortisol levels in the blood from working out. The athletes studied are typically in good physical condition, with a lean body and no symptoms of low testosterone (which doctors say is often more important than your actual levels).

People with higher percentages of body fat and higher body weights are more likely to have low testosterone and experience symptoms, Dr. El-Zawahry adds.

‘You should exercise to keep your endurance, lean muscle, and low body fat, which will, in turn, keep you healthy,’ Dr. El-Zawahry says. This will reduce the risks of metabolic syndrome and reduce health issues associated with it—and those things keep testosterone at a healthy level, he adds.

Which Exercises Impact Testosterone Most?

Research suggests that strength exercises and high-intensity interval training (HIIT) can increase testosterone levels. Endurance-based exercises, like cardio, can potentially reduce testosterone.

Even within resistance training, the ‘greater intensity and greater volume of work’ are more likely to elevate testosterone, Hackney says. For instance, if you’re lifting heavy weights with lots of sets over a 45-minute time period, you’ll see a bigger impact.

‘If they’re a casual resistance trainer, they’re probably not going to see any substantial mark in testosterone changes,’ he adds.

A 2016 study showed that starting resistance training with large muscle groups, like your chest and glutes, and progressing to small muscle groups, such as triceps and shoulders, produced the largest testosterone response. But no exercise is going to drive your T levels through the roof, and it won’t be a prolonged increase.

Testosterone levels usually increase transiently after weights and intense physical activity about 15 minutes to an hour after the workout, Dr. Cherullo said.

Mixing endurance and resistance training likely leads to a “zero-sum game,” when it comes to its effect on testosterone, Hackney says.

Don’t worry so much about just focusing on resistance training because you think it raises your T. Dr. El-Zawahry says any exercise benefits your general health and helps you maintain a healthy body weight and T level.

While there’s research on the subject, Dr. McNeil says yoga and pilates, which incorporate aspects of strength training, likely have a positive impact on testosterone.

How Long Does the T Boost Last After Working Out?

The elevated testosterone that you see from working out is usually temporary—maybe an hour or so, Hackney says. Then, your T levels will return to normal.

‘However, you may feel a good boost of energy with exercise because of a surge in cortisol level rather than testosterone,’ Dr. El-Zawahry says.

Remember, too, that your testosterone levels naturally fluctuate during the day. By exercising, you’ll likely maintain a healthy weight and improve your cardiovascular functioning, which has positive effects on your testosterone.

However, working out alone won’t cause a long-term increase in testosterone levels, Dr. El-Zawahry says.

Will Exercising Affect Your Testosterone Test?

Your testosterone levels tend to be the highest in the morning and then gradually drop throughout the day, Dr. Cherullo said. That’s why doctors typically test your T in the morning.

If you typically run in the morning or take 5 a.m. HIIT classes, it likely won’t affect your test results, Dr. McNeil says. So don’t skip your workout—it’s good for your T levels and your overall health.

VICENZA, Italy — For the handlers of the 525th Military Working Dog Detachment, readiness isn’t just about the mission, it’s about maintaining the total health of their most trusted partners. Through the U.S. Army’s new Canine Holistic Health and Fitness program, the Vicenza-based detachment is redefining what it means to be mission ready, one paw at a time.

The Army established the K9H2F program under Army Directive 2025-16 to enhance the wellness, performance and quality of life of MWDs, Aug. 21, 2025. The directive mandates all Army MWD units to implement comprehensive health and welfare standards, aligning with Department of War and Army veterinary care policies.

Modeled after the Soldier Holistic Health and Fitness system, K9H2F takes a science-based, whole-dog approach addressing physical fitness, nutrition, behavioral health and recovery. For the 525th MWD team, that means every dog receives the same level of conditioning and care as any elite military athlete in uniform.

“Our dogs are tactical athletes,” said U.S. Army Staff Sgt. Payton R. May, kennel noncommissioned officer in charge assigned to 525th MWD Detachment (Vicenza), 18th Military Police Brigade. “They train hard, they work hard and they deserve the same attention to fitness, nutrition and injury prevention that we give our Soldiers. The H2F program helps us keep them in top condition so they can perform safely and effectively in any environment.”

A key component of the directive, the Partner and Wellness program, ensures handlers and their assigned MWDs relocate together during permanent changes of station, strengthening continuity and the human-K9 bond.

“When I PCS’d [permanently changed duty stations] to Italy, being able to bring my dog with me made a huge difference,” said U.S. Army Spc. Matthew C. Skalisky, a patrol explosive detector dog handler assigned to the 525th MWD Detachment. “It helps us maintain that trust and teamwork that can’t be replaced. The PAW program makes sure that bond doesn’t get broken.”

Each MWD now follows structured conditioning routines designed to build strength, endurance and agility while reducing the risk of injury. Specialized diets, recovery protocols and enrichment activities round out their regimen, ensuring each dog remains physically capable and mentally resilient.

According to U.S. Army Sgt. Maj. Viridiana Lavalle, Military Working Dog program manager at Headquarters, Department of the Army, the initiative marks a major step forward in modern K9 care.

“Proactive and data-driven K9 care is essential for optimizing the performance and longevity of MWDs, directly impacting mission readiness and effectiveness,” Lavalle said. “By leveraging advanced analytics to monitor health metrics, exercise regimens and behavioral patterns, handlers can implement tailored care strategies that enhance the holistic health of MWDs.”

This strategic approach not only improves the physical capabilities of these vital assets but also supports K9 mental resilience, ensuring they are fully prepared for the demands of their critical roles.

“Ultimately, investing in comprehensive K9 care through data-driven insights enhances operational effectiveness, contributing to mission success and the overall safety of military personnel,” Lavalle said.

The holistic approach extends beyond the kennel. Handlers train alongside veterinary and behavioral specialists to better understand each dog’s unique needs, improving communication and enhancing mission effectiveness.

“The bond between handler and dog is everything,” May said. “When you have that trust, that connection, the dog performs with confidence. The H2F program helps us strengthen that bond through better training, stress management and recovery practices.”

From explosives and narcotics detection to patrol duties across Europe and Africa, the 525th’s military working dogs play a vital role in safeguarding Soldiers and installations. The K9H2F program ensures those capabilities remain sharp on every mission, in every environment.

Can’t Get To The Gym RN? I’m Opting For Plank Shoulder Taps After A PT Confirmed They’re The Most Effective Home Move

How many times have you said, “I can’t believe it’s December already,” this year? If your answer veers somewhere between “a fair few” and “honestly, I’ve lost count”, you’re in good company. It’s become the seasonal equivalent of asking about the weather – a reliable go-to as the year starts winding down. And while I’ll spare you the usual cosy festive clichés, December is the month when gym plans loosen, and most of us swap weighted plates for quality time and mince pies.

Still, if moving your body is something that helps you feel grounded, there’s no reason you can’t carve out little pockets for it over the festive period (just as there’s absolutely no shame in pressing pause altogether). Research consistently shows that even short bursts of exercise can support both mental and physical health, which is why keeping one or two genuinely effective, at-home moves in your back pocket can be a lifesaver when festive stress starts simmering.
