Explanation: Lie flat on the ground with your knees slightly bent at a 90 degree angle, and your feet flat on the ground. Place your hands across your shoulders or behind your neck. Be sure to not pull on the back of your head in such a position. Curl your trunk upward towards your knees. Do not simply lean forward; arc your body up with your waist, not your head. Your upper back and shoulders should come off the floor. Once you are at the top, squeeze and contract your abdominal muscles hard. Slowly roll back to the starting position where your abdominals are fully relaxed. Repeat the movement.
As with all abdominal exercises, it is very important that you use strict and proper form to achieve results. There are many variations of crunches, all targeting different areas of your abdominals. You can vary the angle of stress on the abdominals by varying your foot height position. You may place your feet on an elevated surface to increase the difficulty. Remember with all abdominal exercises that breathing in as you relax and out as you contract is also very important! Train hard!
