Aerobic exercise is an important component of holistic health. Your doctor probably reminds you often that a healthy heart is one that can work hard, and that’s exactly what aerobic exercise trains your body to do. Also known as cardio, some examples of aerobic exercise include running, cycling, and rowing. But for some, those traditional forms of cardio might be uncomfortable. Whether you have joint pain or simply don’t like being sweaty, you might enjoy doing your cardio in the pool. And don’t worry, you might not have to get your hair wet as traditional swimming isn’t your only option. Allow me to introduce: water aerobics.
