The Water Taxi exercise works your back, shoulders, arms, chest and abs.
Sit on the kickboard and with your arms in front of you, sweep them out to the sides as if you're doing a breaststroke traveling across the pool for 30 seconds. Use the strength in your arms to move. For the next 30 seconds, switch your stroke going in the opposite direction bringing your arms together in front of your body with your palms facing in.
