There are plenty of reasons to swim! Here’s a list that should get you motivated.There’s no ground impact when you swim, and so you protect the joints from stress and strain. In fact, the Arthritis Foundation strongly recommends swimming and water activities for this reason, so much so that they sponsor water classes all over the country (check https://www.arthritis.org for information). Water aerobics classes are also desirable for this reason, because even if you do jump and hit the bottom of the pool, you do so with less force because you’re buoyant in the water.
Not only that, but if you wear or hold a flotation device during a water aerobics class, the impact is even less.Swimming improves endurance. In one study of sedentary middle-aged men and women who did swim training for 12 weeks, maximal oxygen consumption improved 10% and stroke volume (the amount of blood pumped with each beat which indicates heart strength) improved as much as 18%.
