Step-by-step instructions

1. Hang from gymnastics rings, a suspension trainer, or a pullup bar.
2. Contract your lats as you roll your upper body backward and tuck your knees to your chest. Your hips and knees should be bent to 90 degrees with your torso parallel to the floor. Hold, then lower to the starting position.
