Why is water so good for you? Because it cuts down on the gravitational pull. When you move in water, there is less strain on your muscles and joints. That means you can move more freely with less pain. In my case, walking on land really hurt my back. But I could get in a pool and walk laps with ease. I then followed it up with 10 minutes in the hot tub to further relax the muscles. Heavenly!
If exercising is not your thing, you may find that a water workout is the answer. Shop around and see if there is an affordable pool in your area. Many of them will offer water aerobics classes that are fun and a good way to meet people. Or, you can opt for a solitary workout such as walking laps or doing leg lifts on the side of the pool. If you know how to swim then swimming laps, particularly the front crawl and back stroke, will strengthen your core while also giving you a great cardiovascular workout.
Don't be shy. Dive right in for a fun a healthy workout!
