Exercise helps you manage your weight.
When you engage in physical exercise, you burn calories. The more intense the activity, the more calories you burn and the easier it is to keep your weight under control.

Exercise increases muscle.
You need to increase lean muscle mass in order to help support your frame and burn more fat. The higher your muscle content, the more fat your burn throughout the day, even when you're not exercising. More muscle means your body burns more calories per day.

Exercise boosts brain power.
Exercise increases energy levels and increases serotonin in the brain, which leads to improved mental clarity.
