According to WebMD, exercise benefits teenagers by toning the body, strengthening muscles and bones, encouraging a healthy weight and promoting healthy skin. It also improves sleep and mood through triggering endorphins, according to TeensHealth.
According to TeensHealth, exercise triggers the production of endorphins in the body. Endorphins promote a feeling of peace and happiness, which is helpful for teens experiencing mild depression or low self-worth. Exercise also boosts the production of serotonin, a key calming agent in the brain.
As WebMD points out, burning calories during exercise improves the health of the skin and the appearance of the body through fostering toned muscles and a healthy weight. Increased collagen production and blood flow during exercise plumps the skin and creates a healthy skin color. Maintaining a healthy weight boosts the immune system and protects against the development of potentially debilitating conditions such as diabetes and high blood pressure. In addition, the health benefits from exercise and a healthy weight promote healthy aging, as TeensHealth points out.
TeensHealth notes that a complete exercise regimen includes aerobic exercise, strength training, and flexibility programs. Stretching involves range-of-motion exercises, such as yoga, while aerobic exercise gets the heart pumping through endurance training. Strength exercises build muscle by working against resistance from weights.
