Exercise can help the body relieve tension. It helps relax muscles and helps you sleep. Speeds the flow of blood through the body, which move waste products from the brain faster than when you do not exercise. Causes the release of endorphins, which give you an uplifting feeling. Additional strength training is also recommended.
