How to do it
Lie face up with your heels resting in the TRX foot cradles and your legs bent. Crunch your upper body up by pulling your knees toward your chest and lifting your shoulders off the floor, squeezing your abs at the top, then lower with control. Keep the movement smooth and driven by the core.
- 1Abs crunching hard as the knees and chest draw together

Common mistakes
- Yanking with your neck to lift the shoulders
