Brisk water walking can provide an excellent aerobic workout and because water provides more resistance than air, you are strengthening and building muscle as you water walk. In a swim spa you can add the extra resistance of the current.

Stand in waist-deep water with your abdominal muscles firm, tailbone pointed toward the floor, buttocks tucked somewhat to brace your spine in position, shoulders back, and chest lifted (neutral position). Walking in chest-deep water provides more resistance and a more strenuous workout.

Walk as you would on land, placing your heel down first and following through with the ball of your foot. Don’t walk on your tiptoes. Keep your back straight and stomach muscles taut.
