As with any exercise, warming up the abdominal muscles is a great way to prevent injury. This can be done a number of ways:
- Lying on the stomach, using the arms as supports, arch the lower back upward and hold
- Keeping the hips forward, rotate the upper torso 90 degrees left, hold, then come back to the starting position, then rotate the upper torso 90 degrees right, hold then return to the start position.
- Whatever exercise you are about to do, do a mini-set, about 5-8 reps to loosen up before doing your full repetition amount
