Otter Roll

The Otter Roll exercise works your back, abs, butt, and legs. Do as many reps as you can in 30 seconds, rest, then repeat.

Slim Down in a Splash! Otter Roll: This move is not only a whole bunch of fun, but it's a great ab firmer. You're going to use your leading shoulder and hip to drive through the water and use your legs to get you over a full 360 degree turn. Do this for 30 seconds.
