- Jump up to a bar (or step onto a box if you need help reaching), and hang from the bar with both palms facing away from you.
- Use your abdominal muscles to raise both feet as high as you can, keeping your legs straight. Aim for parallel or higher, if you can.
- Hold this position for as long as you can, working up to 20 to 30 seconds.
- This counts as one rep.
