Tips: The elbows are to be locked and kept in a vertical line with the shoulders. Many ab wheel commercials show the user with their arms extended out but it is felt by some that this puts unnecessary stress on the shoulders and lower back. Keep the body locked in a straight position with no back “sag” when in the bottom position. All movement in this exercise is initiated by the hips, not the arms/lats. The emphasis should be on raising the butt as high as possible in a “piking” motion when in the upright part of the movement.

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!

Tips: Lie on your back and put your hands behind your head. Raise your legs so your thighs are perpendicular and your lower legs are just above parallel to the floor. Curl up and bring your left elbow toward your right side while drawing your right knee in to meet it. It is like you are riding a bike. Alternate sides, continuing the motion back and forth. Remember, don’t just flap your elbow across your body, actually rotate your shoulder across and squeeze your abs.

Tips: Using the ab roller, start on the floor on all your hands and knees. Hold the ab roller in your hands while in this position. Slowly roll the ab roller foreward, stretching your body into a straight position. Go down as far as you can without touching the floor with your body. Pause and pull yourself back to the starting position. Repeat for the desired number of reps. Go slow and do not touch the ground!
