Why I do it: This exercise targets the lower abs and makes me able to hold hollow holds longer.
- Lie on your back. Rest your hands by your sides, palms facing down, or place your hands underneath your butt for a little leverage.
- Extend both legs out so they are a few inches above the ground. Draw your lower abs in, pressing your lower back into the floor.
- In one fluid motion, bend your knees into your chest, press your hips up as high as you can, lower your hips to the floor, and extend your legs straight out.
- This completes one rep.
