Master this advanced move, and you'll have those lower abs showing in no time. To modify, you can do this move with bent knees.
- Start by hanging on a pull-up bar with palms facing out, or use the ab straps and hang with your arms inside of them. Do use a box or bench if you need help reaching the bar.
- Pull your shoulder blades down your back to keep your shoulders away from your ears.
- Engage your abs as you fully extend both legs, lifting them up simultaneously with control.
- Lower your legs down slowly and return to the starting position. This completes one rep.
- Avoid swinging during this move to ensure you're really working your abs.
- Do two sets of 10 reps.
