Cross Knees to Elbows

Cross Knees to Elbows

From standing, bring one elbow down across your body to meet your opposite knee, holding your core tight and then switch sides. Yes, you'll look like you're folk dancing in the pool, but if anyone asks just shout "He's after me Lucky Charms!" and they'll leave you alone. Take full advantage of the pool and do this move by heading to the deep end and just bouncing lightly off your toe between each rep. Tip: Isolating the move on one side will burn out your oblique muscles faster.
