Tips: Works your obliques. In order to complete 1 repetition, each heel must be touched once. So, get into position, crunch over and touch your right heel once, then crunch over and touch your left heel once, and now you’ve completed 1 repetition. Lie down on the floor. Bend your knees and keep your feet 18-24 inches apart. Keep your arms straight down at your sides. Crunch forward and up about 3-4 inches. Remember to keep your lower back pressed flat against the ground. Keep your head in a neutral position. Alternate touching your right heel and then your left heel. Remember, touching each heel once is one rep!
