Difficulty: Moderately Easy
Step1
Lie on your back and place your feet flat on the floor. Place your hands behind your head, but don't interlace your fingers. Keep your elbows on the floor or as close to the floor as you can comfortably get.
Step2
Tighten your abdominal muscles to draw your pelvis toward you and press the small of your back against the floor. Keep your abdominals tight throughout the exercise to avoid stressing your back.
Step3
Raise your head and shoulders off the floor. Take care to keep your elbows back to avoid pulling your head forward and injuring your neck. Don't tuck your chin into your chest and try to curl yourself toward your knees; instead, lift your head straight up toward the ceiling.
Step4
Lower your shoulders to the floor, but don't let your head touch the floor. Take care that you don't simply allow yourself to fall back
Step5
Repeat the exercise, working in sets and resting briefly in between, until your abdominal muscles begin to burn with fatigue.
