How to do Crunches
- Lie back with knees bent, feet flat, hands at your temples.
- Curl your shoulder blades off the floor — your lower back stays down.
- Pause one beat at the top, then lower under control.
Momentum flapping. Fast half-bounces look like reps but skip the squeeze that makes crunches work.
