|Muscles worked: Abdominals (Mostly Upper Abs)
Lie on your back on a gym mat or the carpet of your floor. Bend you knees and place your feet flat on the floor about shoulder width apart. Place your hands behind your head and neck and keep them there throughout the entire exercise. Using your abdominal strength, curl your shoulders up and off the floor towards your hips. Keep your head absolutely straight looking upwards throughout the entire exercise. When your shoulders cannot come up any higher, pause there for one second and contract your abdominals. Return to the starting position and repeat for the number of reps assigned.
Note To isolate your lower abs as well, you can raise your hips from the floor as part of the movement.
Don't pull your head up with your hands. This can cause neck injuries. Use your abdominal muscles to raise your shoulders off the floor. Don't bend your neck. Keep it straight throughout the entire movement.
