Muscles and joints loose elasticity. Joints tighten and range of motion decreases. Exercise improves flexibility and range of motion. Maximum heart rate decreases. Resting heart rate and blood pressure increases.
Exercise decreases resting heart rate and blood pressure.
Exercise and strength training increases metabolism. The Surgeon General recommends that Americans engage in physical activity for a minimum of 30 minutes 3-5 days a week.

The message here is to just get moving.
