You may have seen people wrap their fingers behind their head while doing crunches - if you do this, you may accidentally stress your neck muscles. By wrapping your hands across your chest, you spare yourself the possibility of neck pain. Use your ab muscles to smoothly lift your upper body (keeping your neck relaxed) until you have gone as far as you can without lifting your lower back off the ground. Never use jerky movements - these can hurt your back. Begin to lower your upper body back down smoothly and slowly. Each time you reach the top of your crunch, hold this position for a second or two, then let yourself down slowly and repeat. If, at any point, you experience pain in your lower back, stop. After 20 repetitions, rest briefly (less than 1 minute), then do another set of 20. Do 2-4 sets, or go until you "feel the burn" - a light soreness in your abs that signifies the muscles in your stomach have been worked out.

If Number 2 passed the chant to Big Booty, they would say, "Big Booty, Big Booty, Big Booty!"
