For centuries, the notion that abstaining from sex increases physical performance has been widely debated. From ancient Greek athletes to modern-day boxing legends such as Muhammad Ali and Mike Tyson, have practiced sexual restraint in the expectation of increasing strength, stamina, and hope. The famous scene in Rocky where trainer Mickey Goldmill tells Rocky Balboa to "lay off that pet shop dame", “women weaken legs,” further fueled this belief, reinforcing the belief that sex before competition weakens the body. But does science back this up, or is it merely an outdated myth?

The theory that sex saps energy and impairs performance goes back almost 2,000 years. Abstaining, ancient Greek athletes believed, would enhance aggression and concentration, leading them to become stronger competitors. Even today in the world of sports, people stick to this hypothesis despite the changing scientific findings. But during the Rio 2016 Olympics, officials gave away a staggering half a million condoms to participants—far from a indication that sex was being thought of as a performance-sapping activity.

Although some continue to abstain prior to major events, the real effect of sex on sports performance is still controversial. Is there any basis to the belief that sex inhibits strength and endurance, or is it merely an old wives' tale?

Role of Testosterone in Athletic Performance

Testosterone is an essential hormone that is essential for muscle growth, power, and overall athletic performance. Although men naturally produce more than women, both sexes need testosterone for energy and recovery. Some athletes think not having sex maintains their testosterone levels, providing them with an advantage in the gym or on the field. But is this statement scientifically accurate?

Studies indicate that testosterone levels are not consistent throughout the day but are constantly being produced in the body. Unlike glycogen, which can be stored and used as energy, testosterone is controlled according to the needs of the body. Research does not indicate that having sex depletes testosterone levels significantly—if anything, it can increase them slightly through endorphin and dopamine release.

Does Abstinence Make One Stronger and More Enduring?

Some fitness enthusiasts skip sex before hard workouts because they think it takes away their energy. Although intense physical exercise (including sex) can cause temporary tiredness, there is no scientific evidence to support that sex deteriorates long-term strength or endurance.

A 2016 review article in Frontiers in Physiology reviewed nine studies of sex and performance in sports, and concluded there was no basis to believe sexual activity prior to competition would cause the body to be weakened. Another study, published in 2019 in the Journal of Sexual Medicine, found no statistically significant effect of sex on performance.

Whereas sex shortly before intense exercise may make you momentarily lethargic, it will not impair general performance, stamina, or muscular power. As an alternative, taking sufficient rest, eating appropriately, and exercising with a standard program are many more significant variables.

Can Men 'Save' Their Testosterone Through Abstinence?

It is long believed by some men that ejaculation abstinence will result in a dramatic increase in testosterone. In 2003, researchers from China claimed that men who did not ejaculate for seven days experienced a short-term 45% rise in testosterone. Yet this response was not found to last past the seventh day, and subsequent experiments have been unable to duplicate this effect regularly.

Conversely, some studies show that testosterone levels actually increase slightly after sex, undermining the idea that abstinence is required for optimal performance. The bottom line? The body has a fine balance of hormone production, and sex abstinence is not likely to give any real athletic benefit.

Even though there is no scientific basis, most athletes still feel that sex impacts their performance. It may be because of the placebo effect—if a player believes that not having sex makes him or her stronger, he or she will be more confident and play better. Some players may also feel relaxed and more alert after sex, and this clears their minds for the competition.

Finally, the psychological effect of sexual activity can differ from individual to individual. Sports persons who believe abstinence allows them to remain aggressive may decide to abstain from sex prior to a big event. There are others who believe that sex helps in reducing stress and enhancing sleep and may gain from intimacy pre-competition.

So, Should You Avoid Sex to Enhance your Performance at Gym?

Although the concept of forgoing sex to enhance gym performance has been around for generations, new research indicates that it does not have any noticeable effect on physical ability. Strength, stamina, and overall performance are more affected by training, nutrition, recovery, and psychological readiness than by sex.

If you think that abstinence makes you more aggressive and focused, you can do so without any ill effects. If sex makes you sleep better and relax, you might be increasing your performance rather than diminishing it. The message here is that there's no one-size-fits-all principle—players have to listen to their bodies and play in whatever way best suits them.

Ultimately, there is no scientific rationale for not having sex before you go to the gym or to compete. Whether you abstain or not, therefore, the outcome of your workout will come down to the effort you make, not the activity in the bedroom.

Long considered a standard tool for assessing body weight, Body Mass Index (BMI) may not be as reliable as once believed. A new study shows that relying on BMI can incorrectly classify people as overweight or obese.

When a team of Italian researchers used the gold standard technique of dual-energy X-ray absorptiometry (DXA) to measure body fat in the general population, they found that the traditional WHO-approved BMI classification system misidentified a significant number of people as having overweight or obesity.

How Is The BMI Wrong?

A total of 1,351 adults of mixed gender aged between 18 and 98 years were checked for their body weight using the DXA system.

The results, published in the journal Nutrients, revealed that more than one-third (34 percent) of those with obesity defined by BMI had been misclassified and should be in the overweight category.

For those with an overweight BMI, DXA showed that more than half – 53 percent – had been misclassified – three quarters of those misclassified fall into the normal weight category, while the other quarter should have been classified as having obesity.

The DXA analysis found that the prevalence of overweight and obesity across the cohort was around 37 percent overall (23.4 percent overweight, and 13.2 percent obesity, compared to 26.2 percent and 14.1 percent with BMI).

“In the past few years, there has been a lot of criticism of the BMI system due to its inability to accurately capture body fat percentage or distribution, to correctly categorise weight status based on adiposity,” said Professor Marwan El Ghoch, of the Department of Biomedical, Metabolic and Neural Sciences, University of Modena and Reggio Emilia, Modena, Italy.

Despite these concerns, BMI as a weight classification system continues to be used in the general population in primary healthcare (i.e., general practitioners) and non-clinical (i.e., policy and health insurance) settings, he added.

The researchers urged revising public health guidelines to consider combining direct body composition or their surrogate measures, such as skinfold measurement or body circumference, with the waist-to-height ratio, with BMI, while assessing weight status in the general population.

Waist-to-Height Ratio May Be More Accurate: The India Story

In January 2025, India revamped its obesity guidelines, and the new approach focused on abdominal obesity and comorbid diseases, rather than just BMI.

According to the redefining team, it was essential to move beyond BMI-only approaches to tackle the ever-growing number of people related to other major health risks. They stated that while BMI can be a screening tool, obesity must be defined by body fat.

“BMI should be used for screening purposes, but obesity should be confirmed ideally by a measure of body fat wherever feasible, or another measure such as waist circumference, WHR, or Waist-to-height ratio,” Dr. Naval Vikram, Professor of Medicine, at AIIMS, New Delhi, was quoted as saying to IANS at the time.

What Do The New Guidelines Say

It recognizes abdominal fat — closely linked to insulin resistance — as a key factor in the diagnosis. It integrates the presence of comorbidities — such as diabetes and cardiovascular disease — into the diagnostic process.

The revised guidelines also introduce a two-stage classification system, addressing both generalized and abdominal obesity.

Stage 1 Obesity: Increased adiposity (BMI > 23 kg/m²) without apparent effects on organ functions or routine daily activities.

Stage 2 Obesity: Advanced state of obesity with increased BMI more than 23 kg/2, and abdominal adiposity; excess Waist Circumference or Waist-to-Height Ratio.

What if your gym routine is doing far more than helping you stay fit? Research is increasingly showing that exercise, especially strength training, plays a powerful role in keeping your brain sharp, focused and resilient over time. In fact, Dr Sudhir Kumar, a neurologist at Apollo Hospital in Hyderabad also pointed this out by quoting the study Randomised Controlled Trial of Resistance Exercise and Brain Ageing Clocks.

The study showed that resistance training could reduce brain age by up to two years. This means strength workouts could help the brain maintain characteristics that are seen in younger people.

It Is Not Just About Muscles

For a long time, workouts were seen as a way to build muscle or lose weight. Now, experts suggest that resistance training can also support brain health in meaningful ways. Regular strength training has been linked to slowing down brain ageing, with some studies suggesting it may even reduce the brain’s biological age by a couple of years.

This means that beyond physical strength, your brain could function more efficiently, particularly in areas like memory and reasoning.

Sharper Focus And Better Memory

One of the most noticeable benefits of working out is how it improves everyday thinking. People who engage in regular strength training often report better focus, improved memory and stronger decision-making abilities.

It becomes easier to stay on track with tasks, manage distractions and process information more clearly. Over time, these small improvements can make a big difference in both personal and professional life.

What Happens Inside Your Brain

The real transformation happens beneath the surface. Exercise triggers the release of chemicals that support brain cells and strengthen the connections between them.

This helps improve neuroplasticity, which is the brain’s ability to adapt, learn and form new memories. It also supports white matter, the network that allows different parts of the brain to communicate effectively.

In simple terms, your brain becomes faster, more flexible and better at handling challenges.

A Natural Way To Reduce Brain Fog

Exercise also helps tackle inflammation in the body, which is often linked to brain fog and cognitive decline. Strength training supports anti-inflammatory processes that protect brain health over time.

This is why many people feel mentally clearer and more energized after a consistent workout routine.

You Do Not Need Intense Training

The best part is that you do not need extreme workouts to see benefits. Experts suggest that even two to three strength training sessions a week can support brain health.

Simple movements like squats, push-ups or resistance band exercises are enough to activate both your body and mind.

Today, the fitness scene has gained much traction among the Gen Z population. With more and more young people spending time in the gym and working out, it is important for fitness enthusiasts to remember the importance of leg stiffness and its impact on spine health. Leg stiffness has the potential to cause unnecessary strain on the spine and back during workouts.

From a neurosurgical point of view, we see that the spine is not just a mechanical support structure but a sensitive pathway through which the spinal cord and nerve roots run. Repeated micro-strain caused by poor flexibility can cause young patients to suffer early degenerative changes that may cause nerve irritation.

We also see that strengthening the abdominal muscles is essential in stabilizing the spine, thereby preventing disc injuries. Early intervention in minor complaints, such as back stiffness or nerve pain, is essential in preventing more serious problems that may need surgical intervention.

The Link Between Leg Stiffness And Spine Health

The muscles in your legs are important for your spine's health. The hamstring, hip flexor, and calf muscles are all significant players in the movement and positioning of your spine. Leg stiffness has the potential to cause unnecessary strain on the spine and back. Leg stiffness limits the movement and positioning of the hips and the spine.

When these muscle groups are tight, they alter pelvic alignment and increase load on the lumbar spine. Over time, this abnormal biomechanics can lead to disc stress and facet joint overload.

In neurosurgical practice, we often see young patients presenting with early symptoms of nerve compression where underlying muscle imbalance and stiffness play a contributory role.

Common Gym Mistakes That Increase The Risk

For young people, the main focus in the gym is on strength training, while flexibility and rest are ignored. This makes the condition of the legs stiffer. Another common error is improper posture while performing certain exercises in the gym. When the legs and hips are inflexible, proper posture is difficult, which causes pressure on the spine.

Sitting for a long time, studying, playing games on gadgets, etc., causes the hip flexors and the hamstring muscles in the legs to become stiffer, which causes pressure on the spine.

From a clinical standpoint, improper lifting techniques combined with stiffness can increase the risk of lumbar disc prolapse and nerve root irritation, conditions frequently encountered in spine clinics.

Tips to Prevent Spine Problems In The Gym

• Warm-ups: It is important to warm up the body before performing weightlifting exercises in the gym. It is recommended that the warm-up process take at least 5–10 minutes.

• Flexibility: It is important to include flexibility exercises in the gym routine, as they help in the proper movement of the legs, which in turn helps in preventing spine problems.

• Proper Posture: It is important to maintain proper posture while performing certain exercises in the gym, like squats, deadlifts, etc.

• Stretching After Workouts: This will help in the release of tension in the muscles and prevent the buildup of stiffness.

• Balance of Training and Recovery: This will help in maintaining the flexibility of the muscles and the spine.

Additionally, from a neurosurgical perspective, core strengthening plays a crucial role in stabilizing the spine and reducing the risk of disc-related injuries. Early attention to minor symptoms like back stiffness or radiating pain can prevent progression to more serious conditions requiring intervention.

Common Spine Problems To Avoid

Common spine problems to avoid during gym workouts include Herniated Disc, Sciatica, Spondylolisthesis, and Muscle Strain. These can occur from poor form, heavy lifting, or lack of warm-up.

In advanced cases, such conditions may lead to nerve compression requiring specialized evaluation and, rarely, surgical management. However, most of these issues are preventable with correct technique and conditioning.

Fitness enthusiasts in the Gen Z generation need to understand that it is very important to develop strength in the body while at the same time maintaining flexibility. The solution to the problem of a stiff leg is the foundation of protecting the spine and improving workout performance. This is achievable through the right warm-up, correct workout, and correct lifting.
