The Risks of doing Arms Up Crunch
While the Arms Up crunch is a popular core move, it isn’t safe for everyone. It can place a lot of stress on your back and neck so, if you have any prior injuries in those regions, you should avoid this exercise.


How To Do Arms Up Crunch
1. Lie down on your back. Plant your feet on the floor, hip-width apart. Bend your knees and place your arms out over your head. Contract your abs and inhale.
2. Exhale and lift your upper body, keeping your head and neck relaxed.
3. Inhale and return to the starting position.
For Perfect Technique
• If the movement comes from your head or neck, you’ll increase the risk for injury. Use your core to raise your upper body.
• Move in a slow & controlled manner. Rapid movements won’t engage your muscles effectively.
• You can place your hands behind your head, but this can strain your neck. It’s best to try this hand placement after you’ve mastered the proper form.
