What You'll Learn
Weight training improves sleep quality better than cardio
It is a well-known fact that exercise can improve your sleep. While aerobic exercise is great for your health, it is not the only type of exercise that can help you sleep better. According to research, weight training or resistance training can improve sleep quality better than cardio.
Research Findings
Researchers in Japan analyzed 27 studies that looked at non-drug methods to improve sleep in younger and middle-aged adults. They compared exercise, diet, and sleep hygiene practices. The findings, published in the journal Plos One, showed that for adults under 65, resistance training is the best non-drug way to improve sleep quality, beating out cardio.
Another study, presented at an American Heart Association (AHA) conference in March 2022, found that individuals who regularly completed resistance training slept better and longer than those who participated in cardio exercise. This study included more than 400 overweight or obese adults who were not physically active.
Benefits of Weight Training
Weight training may improve sleep by reducing anxiety and stress, benefiting heart health, and promoting muscle recovery. It can also help with mental health issues such as anxiety and depression, which can often hinder sleep. Additionally, weight training can increase blood flow, which is beneficial for people with high blood pressure.
Recommendations
The American Heart Association recommends strength training at least twice a week. The U.S. Department of Health and Human Services guidelines suggest adults do muscle-strengthening activities at least two days a week, in addition to aerobic activity.
To improve sleep quality, consider incorporating weight training into your weekly routine. This can include exercises such as leg press, chest press, lat pulldown, bicep curl, and abdominal crunches. You can use weight-lifting machines, resistance bands, or even your own body weight.
While cardio is important for overall health, weight training has been shown to be more effective in improving sleep quality, especially for adults under 65. By incorporating weight training into your fitness routine, you may be able to achieve better sleep and reap the additional health benefits that come with it.

Sleep is essential for muscle repair and growth
Sleep also plays a vital role in regulating hormones that are key to weight training and general health. For instance, testosterone helps build muscle mass, and a lack of sleep can cause a decrease in testosterone levels. On the other hand, sleep deprivation is linked to increased levels of cortisol, a hormone that breaks down muscle tissue.
Additionally, sleep is vital for maintaining mental focus and concentration throughout the day. When you are well-rested, you are more likely to stay focused on your fitness goals and push through challenging workouts. Weightlifting requires a great deal of mental focus, as you perform strenuous and technical movements under heavy loads. A lack of sleep can lead to decreased mental acuity, resulting in poorer performance.
To optimise your sleep for muscle repair and growth, consider the following tips:
- Stick to a consistent sleep schedule. Go to bed and wake up at the same time every day, even on weekends. This helps regulate your body's natural sleep-wake cycle.
- Establish a relaxing bedtime routine. Engage in activities that help you relax your mind and lower your heart rate, such as taking a warm bath, reading a book, or practising meditation or deep breathing exercises.
- Create a sleep-conducive environment. Ensure your bedroom is dark, quiet, and cool. Invest in a comfortable mattress and pillows. Limit your exposure to electronic devices, especially screens, before bedtime, as the blue light emitted by these devices can disrupt your sleep.
- Avoid exercising too close to bedtime. Working out elevates your body temperature and can leave your mind wired, making it difficult to fall asleep. Try to end your workouts at least three to four hours before bedtime.

Lack of sleep negatively impacts training performance
Sleep is an essential biological process that allows our bodies to reset, heal, and recover. When it comes to weightlifting and strength training, getting adequate sleep is crucial for optimal performance and progress. Lack of sleep can negatively impact training performance in several ways:
Impaired Muscle Recovery
During sleep, the body releases growth hormones that are crucial for muscle repair and recovery. Weightlifting creates micro-tears in the muscle tissue, and without enough sleep, the body may not have sufficient time to fully recover and repair these tears. This can lead to suboptimal performance in the gym and hinder your progress over time.
Hormonal Imbalance
Sleep is important for regulating hormones that play a key role in weight training and overall health. Testosterone, for example, is essential for building muscle mass, and lack of sleep has been linked to decreased testosterone levels. On the other hand, sleep deprivation is associated with increased levels of cortisol, a hormone that can break down muscle tissue. This hormonal imbalance can negatively impact training performance and hinder muscle growth.
Reduced Mental Focus and Concentration
Sleep is vital for maintaining mental focus and concentration throughout the day. When you are well-rested, you are more likely to stay focused on your goals and push through challenging workouts. Weightlifting requires a great deal of mental focus and technical movement patterns under heavy loads. Lack of sleep can decrease mental acuity, leading to poorer performance and increased risk of injury.
Increased Risk of Injury
Inadequate sleep can also increase your risk of injury during training. Sleep allows the body to heal and recover, and without enough of it, you may experience decreased muscle function, impaired coordination, and reduced reaction time. This can make you more susceptible to injuries, especially when handling heavy weights.
Decreased Energy Levels
Sleep helps restore energy levels, and when you are sleep-deprived, you may experience decreased energy and endurance. This can impact your training performance, making it difficult to maintain intensity and complete your workouts effectively.
In conclusion, lack of sleep can have detrimental effects on training performance. It is important to prioritize sleep by maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and optimizing your sleep environment. By improving your sleep quality and duration, you can enhance your training performance, promote muscle recovery, and support overall health and well-being.

Sleep regulates hormones important for weight training
Sleep is an essential biological process that allows our bodies to reset, heal, recover, and maintain physical, mental, and emotional health. It is vital for regulating hormones that play a key role in weight training and general human health. Here are some ways in which sleep regulates hormones important for weight training:
Growth Hormone
During sleep, the body releases the growth hormone, which is crucial for muscle repair and recovery. When you undergo resistance training, you put your muscles under stress to create micro-tears in the tissue. Without adequate sleep, the body may not have enough time to fully recover and repair these muscle tears, which can lead to suboptimal performance and hinder your progression.
Testosterone
Testosterone is an important hormone for building muscle mass, and lack of sleep has been shown to decrease testosterone levels. Therefore, sufficient sleep is necessary to maintain healthy testosterone levels, which in turn promotes muscle growth and strength.
Cortisol
Cortisol is a hormone that can break down muscle tissue, and sleep deprivation is linked to an increase in this hormone. Elevated levels of cortisol can negatively impact training and progress by breaking down muscle tissue faster than the body can repair it, potentially leading to muscle loss and decreased strength.
Adrenaline and Endorphins
Weightlifting and strength training increase adrenaline and endorphin levels in the body. While these hormones are beneficial during exercise, they can interfere with sleep if workouts are done too close to bedtime. It is recommended to avoid exercising within three to four hours of bedtime to allow the body to cool down and for these hormone levels to regulate, promoting a better night's sleep.
Melatonin
Melatonin is a hormone that helps the body maintain its circadian rhythm, or sleep/wake cycle. Exposure to artificial light from electronic devices before bed can suppress the natural release of melatonin, disrupting sleep. Turning off electronic devices 30 minutes before bed and creating a dark and quiet environment can help regulate melatonin levels and improve sleep quality.

Weightlifting requires a lot of mental focus, which is affected by sleep
Sleep is essential for our physical and mental health, and plays a critical role in our overall quality of life. Weightlifting is a strenuous activity that demands a great deal of mental focus and technical movement patterns under extreme heavy loads. When we are well-rested, we are better able to stay focused on our goals and push through challenging workouts.
Lack of sleep can impair cognitive function and decrease mental acuity, which can lead to poorer performance in the weight room. This is because sleep is vital for maintaining mental focus and concentration throughout the day. Weightlifting is not just a physical activity, it requires a great deal of mental focus and concentration as well. The technical movement patterns and extreme heavy loads involved in weightlifting demand a lot of mental energy, and sleep deprivation can negatively impact our ability to perform these complex movements.
In addition, sleep plays an important role in muscle recovery and repair. During sleep, the body releases growth hormones that are crucial for muscle repair and recovery. Without adequate sleep, the body may not have enough time to fully recover, which can lead to suboptimal performance and hinder progress in the weight room.
Furthermore, sleep helps to regulate hormones that are important for weight training and general human health. For example, testosterone is a key hormone for building muscle mass, and lack of sleep has been shown to decrease testosterone levels. On the other hand, sleep deprivation is linked to increased levels of cortisol, a hormone that can break down muscle tissue.
Therefore, it is important for weightlifters to prioritize sleep and establish healthy sleep habits. This includes sticking to a consistent sleep schedule, creating a relaxing bedtime routine, and making changes to the sleep environment to promote a cool, dark, and quiet space. By improving the quality and quantity of sleep, weightlifters can enhance their mental focus and concentration, support muscle recovery, and optimize their performance in the weight room.
