"Hi my name is Sue Conrad and I'm going to show you how to do an abdominal crunch. You start with your back lying flat on the floor. Your feet are going to be slightly bent. You are going to put your hands gently behind your head for just slight support. You are going to raise your torso off the mat keeping the low back firmly pressed on the ground. We're just going to raise it up as far as you can. Keeping proper form and technique. Feeling the abs contract, holding for a second and then lowering down nice and slow. You are going to focus on your breathing as you raise up, you are going to exhale. Bring it up as far as you can comfortably till you feel the abs contract and then lower. Now remember this is not a sit up, this is a crunch, so you are not coming, you are not raising your low back off the mat. You are just coming up just slightly. What I suggest is to do two to three sets of fifteen reps, just be really mindful of the low back, as you bring your body up, keep your neck and shoulders relaxed. Keeping your arms nice and open. Exhale on the way up, holding briefly and lowering. And this is how you do an abdominal crunch."
