For individuals looking to improve sleep, could weight training be the answer to increase healthy sleep?

Weight Resistance Training

Researchers found that resistance weight training improves sleep quality, among other methods like diet and sleep hygiene practices. Resistance training may improve sleep by reducing anxiety and stress, benefiting heart health, and promoting muscle recovery. Researchers examined non-medication methods of improving sleep in younger and middle-aged adults, comparing exercise, diet, and sleep hygiene practices. The findings showed that for adults under 65, resistance training is the best non-pharmacological way to improve sleep quality. (Hirohama, K. et al., 2024) These findings reinforce that sleep and exercise lead to improved restful sleep. Resistance training is highly effective compared to aerobic exercise (running or cycling) in improving sleep quality. The research shows that resistance exercise has more profound benefits than aerobic training alone.

Resistance Training and Improved Sleep

Resistance training, also called strength training or weight training, is intended to build muscle and strength using resistance. This can include:

• Your body weight
• Resistance bands
• Free weights
• Weight-lifting machines

The mechanisms by which exercise alters sleep are unknown. However, the researchers point out that weight training may improve sleep by improving mental health issues such as anxiety and depression. (Cunningham J. E. A., & Shapiro C. M. 2018) (Carbone E. A. et al., 2023) Other research on resistance training and sleep found that resistance training helped decrease anxiety and stress. (Alley J. R. et al., 2015) Resistance training can benefit heart health as it increases blood circulation. This means the heart’s vessels don’t have to work as hard during sleep when blood pressure should naturally drop, which is known as nocturnal dipping, which is great for individuals with high blood pressure.

Another reason this training may help with sleep is its impact on the body. Previous research on resistance training and sleep suggests that since weight training stresses muscle tissue, it could signal the brain that sleep is needed to repair the damage (Iowa State University, 2022). The hormone adenosine, which helps promote sleep, is a key factor in why exercise increases adenosine levels and helps the body doze off. (Roig M. et al., 2022)

How Much Resistance Training Is Needed?

Sleep doctors advise patients to perform some form of daily movement or exercise to improve sleep. The amount of resistance training an individual needs depends on their circumstances, such as underlying conditions, injuries, fitness level, physical ability, and time.

• General guidelines from the American Heart Association recommend strength training at least twice a week.
• The guidelines for physical activity from the Department of Health and Human Services recommend adults do a muscle-strengthening activity at least two days each week in addition to at least 150 to 300 minutes of moderate-intensity aerobic activity.
• The meta-analysis research found that a 55-minute resistance training session consisting of three sets of 10 to 12 exercises done three times a week positively affected sleep quality.
• They added that higher intensity and frequency of training could have a greater effect on sleep.

In other research on exercise and sleep, study participants were grouped into resistance training, aerobic, and combination workouts – both resistance and aerobic exercise. Each group engaged in 60-minute training sessions three times a week, with the combination group doing 30 minutes of resistance training and 30 minutes of aerobic exercise each session. (Iowa State University, 2022) Resistance training increased sleep by an average of 40 minutes compared to about 23 minutes for those who did an hour of aerobic exercise. A combination of aerobic and resistance increased sleep by about 17 minutes. (American Heart Association, 2022)

Previous research on resistance training and sleep found that exercise at any time can improve sleep quality compared with no strength training. However, evening sessions tend to help individuals sleep a little better. (Alley J. R. et al., 2015) Resistance exercise may offer benefits regarding the ability to fall asleep and stay asleep for those with osteoporosis, sarcopenia, anxiety, or depression.

Strength Workouts

Resistance training that targets all the major muscle groups is the goal. The Iowa State University research had participants use 12 resistance machines to perform exercises, including:

• Leg presses
• Chest presses
• Lat pulldowns
• Bicep curls
• Abdominal crunches
• Participants performed three sets of eight to 12 reps at 50% to 80% of their one-rep max. (Iowa State University, 2022)
• One of the studies had participants work out for 30 minutes using nine different resistance machines, completing three sets of 10 reps. (Alley J. R. et al., 2015)

However, individuals can also use dumbbells such as bicep curls or chest presses, barbells for deadlifts or back squats, resistance bands for lateral shoulder raises or leg extensions, or their body weight for movements such as chin-ups or push-ups.

Other Ways to Improve Sleep Without Meds

Other non-drug methods to improve sleep include a healthy diet, proper hydration, dietary changes, and stress management like meditation. Aerobic exercise is known to improve both sleep quantity and quality. (Kovacevic A. et al., 2018) Lifestyle behaviors outside exercise are also important for sleep. Sleep hygiene refers to having healthy sleep habits and behaviors at night. This includes optimizing pre-bedtime routines to prepare the mind and body for sleep and improving bedroom environments to ensure sleep support, meaning it is cool, dark, quiet, and free from distractions like phones. Another important method of improving sleep is listening to your body and not forcing yourself to stay up late when exhausted. Pushing the brain and body to stay up later leads to chronic sleep debt. Eating sugary and high-fat foods before bed can hinder sleep patterns. Drinking caffeine after dinner or close to bedtime can disrupt the sleep cycle, as well as alcohol consumption before bed can hurt sleep quality.

Injury Medical Chiropractic and Functional Medicine Clinic

Individuals need rest time to adjust to working out, so consult a doctor on the balance of rest and training. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop an optimal health and wellness solution. We focus on what works for you to relieve pain, restore function, and prevent injury. Regarding musculoskeletal pain, specialists like chiropractors, acupuncturists, and massage therapists can help mitigate the pain through spinal adjustments that help the body realign itself. They can also work with other medical professionals to integrate a treatment plan to resolve musculoskeletal issues.
