Swimming and aquatic exercise in general are popular alternatives to land-based activities

such as walking or biking.

The buoyancy helps take some of the weight-bearing stress off the joints, but swimming appears

Obeswomen were randomized into an hour a day of walking, cycling, or swimming.

Six months later, the walkers lost an average of 17 pounds.

The cyclists lost an average of 19 pounds, and the swimmers didn't lose an ounce.

The more the women walked, the more they lost weight.
