This functional move targets your abs in a way that you use them every day--but sitting up was never so tough!
How to do it: Start lying on your back with your right knee bent, foot flat on the floor, and left leg extended straight out on the floor. Extend your right arm to the ceiling and reach your left arm towards your left foot. Sit all the way up, rolling through your back, keeping your right foot on the floor, and your right arm up over your shoulder and your left arm reaching in front of you all the way up. Slowly roll back down to the floor. That’s one rep. Repeat 15 times on one side, 15 times on the other.
Bonus tip: Hold a 3-5 pound dumbbell in your top hand to add even more of a challenge to this move.
