If you are looking to get in shape, pool workouts are always a good idea. Here are the best swimming workouts.
Hold a kick board at arms length in front of you and kick back and forth across the pool.
This is exactly as it sounds. Run in the pool.
Float on your back. Put legs, from the knees up, on side of pool, while the remainder of your body is flat in the water. Use your abdominal muscles to pull your upper body up out of the water as far as you can
Swim continuous laps with whatever stroke you feel comfortable with.
