Tennis is an excellent cardiovascular exercise that improves muscular strength, endurance, balance, coordination, and agility. Playing the sport requires every muscle in your body to fire which makes it a whole body workout. Tennis also recruits your large lower body muscles for quick side-to-side and front-to-back movements and your upper body muscles to help you swing the racket. Playing tennis can be a great cardio workout which promotes heart health. It also helps reduce stress levels. Plus it is a social game, so you can exercise with your friends which increases social interactions & boosts your mood. Moral of the story, TENNIS IS AWESOME
