Stand in chest deep water in a lunge position with one leg forward. Sink down as low as possible until a stretch is felt in the front of your back thigh. Keep your spine upright. Hold a frisbee between your palms with straight arms.
Keeping your arms out in front and the frisbee in line with your chest bone, rotate your trunk and head to one side as far as possible, but keep your pelvis and legs still. Return to the starting position and repeat to the other side.
