SETUP: Lie flat on the floor. Bend your knees and then raise your legs until you have a 90 degree angle. Hold a medicine ball above your head.
REP: Crunch up by squeezing your abs hard. Notice the slight movement of my pelvis? I’m trying to tilt my pelvis towards my abs for an even better contraction. The ball should travel towards your feet.
TIP: Most people get the breathing dead wrong on this exercise. Either they hold their breath, or they breath out during the crunch. While the second approach is definitely better than the first, there is a superior way. Start breathing out BEFORE you start the rep, and continue breathing out as you hit the crunch. You’ll feel these like never before.
