How to do it
- Lie on your back with your knees bent and feet flat on the floor.
- Rest your fingertips lightly beside your head without locking your fingers.
- Tighten your stomach and lift your shoulders a little off the floor, keeping your lower back down.
- Pause, then slowly lower your shoulders.
Beginner tip: Don't pull on your head; let your stomach do the lifting.
