How to do it
Sit on the edge of a padded stool and lean your torso back slightly, gripping the sides for support. Raise one knee toward your chest while twisting your torso so the opposite elbow rotates toward that knee. Lower under control and alternate sides, driving the rotation from your obliques each rep.

Common mistakes
