Quality Crunches!
Do a quality-control check of your form while doing crunches.
Begin on the floor on your back with your knees bent and feet flat on the floor. Place your hands behind your head, with your elbows wide. Lift your chin off your chest. Slowly lift your shoulders up off the floor sliding your ribs toward your hips. You should feel the ab muscles engage. Exhale, and lift up 1-2 inches higher, that’s it. Pause at the top of your range of motion. Inhale, and slowly lower your shoulders to your starting point, not all the way to the floor. Pause at your starting point. Start with 10 reps.
*Consult your physician before performing exercise.
