You can get a great total body workout in a pool, and not just in the lap lanes. How about trying a class that uses treadmills in the water or lets you spin on an aqua cycle?
You can also burn calories and strengthen your cardiovascular system. Plus, there's an added benefit you don't get on land: Water is denser than air, so it provides more resistance. That means you're challenging your muscles in a different way.
Stretching with aqua yoga or aqua Pilates may also help improve agility and flexibility.
Water workouts are less punishing on your body. You're buoyant in water, so there's less pain and stress on your hips, knees, and other joints. That may allow you to stay active longer.
Consumer Reports suggests looking around for water classes near you. If you can't find a program, you can get the same benefits by walking briskly in a pool's shallow end or wearing a flotation belt to run in deep water. Whatever you choose, do it at a moderate intensity at least twice a week to reap the rewards.
