Aquatic exercises

Once you're comfortable walking in waist-high water, try walking in deeper water. As you walk, swing your arms. Keep your back straight, and tighten your abdominal muscles to avoid leaning too far forward or to the side.

To help you stay above the water, you might place a water noodle between your legs. Make sure the noodle is higher in back than in front. If you don't know how to swim, wear a flotation vest or float belt in deep water. To increase resistance as your hands and arms move through the water, wear hand webs. Water shoes can help you maintain traction on the bottom of the pool.

For a more intense workout, consider jogging in deep water.
