In this tutorial, we learn how to do leg up touch crunches for the abdominals. First, lay down flat on the ground with your arms opened out on both sides. Next, raise your legs up into the air so they are vertical to your body. Now, raise your upper body into the air, touching your ankles as you get up higher. The goal is to reach the outsides of your ankles as you get up, but touch as high as you can. When you're done, go back to your starting position and continue this exercise for as many time as you can.
