Follow These Steps:
Step 1. While laying on your back with your feet flat on the floor, bend your knees.
Step 2. Position your hands behind your head. You can also place your hands across your chest. Be sure not to use your neck to raise into the crunch. This puts stress on the neck and spine.
Step 3. While tightening (contracting) your abdominal muscles, exhale and lift your shoulder blades off the floor. Now bend your abs towards your knees. Do not bend your elbows. Keep them spread out. Find a spot on the ceiling to focus on. This aids in keeping your head in a proper position.
Step 4. While still tightening your abdominal muscles, hold for a few seconds then inhale as you slowly lower back to the starting position. Repeat these steps to complete your desired sets.
Tips
