Crunches

Short range, honest tension. The floor version of 'quality over quantity'.

How to do Crunches

1. Lie back with knees bent, feet flat, hands at your temples.
2. Curl your shoulder blades off the floor — your lower back stays down.
3. Pause one beat at the top, then lower under control.

Where reps get stolen

Momentum flapping. Fast half-bounces look like reps but skip the squeeze that makes crunches work.
