The Vertical Breastroke exercise works your abs, butt, hips and inner thighs.
Treading water in the deep end and holding the kickboard above your head, flex your feet and then bend your knees in front of you to bring your heels toward your butt. Quickly press your legs down and diagonally outward, pointing your feet then bring your legs together and repeat. Do this for 1 minute.
