The Master Stroke

Teach your family a few strokes and they'll have a valuable workout that will last them a lifetime. Swimming is a great overall exercise that's easy to master as a child and gentle enough on the body to take up later in life. And it has the benefits of requiring little gear and being completely portable. All you need is a swimsuit and a swimmable body of water.

Look for family swimming lessons at your local public pool or health club. Even infants can get into the act.
