Exercise: Crunch

Yep, this is similar to the sit-up of the PFA. The differnece is you will be less likely to injure your back ith crunches then with a sit up. Take a look at the sailors below.

They are doing situps. The difference with crunches are:

• You keep your hands behind your head, but do not use them to pull yourself up.
• Your lower back stays on the ground.
• You do not touch your knees or legs.

To do a crunch

• Pause breifly in the up position.
• Do not jerk yourself up. Keep control of your movement.
• Try it with your feet together, and apart.
