How to build lower abs
Start on your back with your knees bent.
Lie with your feet flat on the floor and palms facing down. For extra support, spread your arms out straight to each side.

Select from:
- Lie on a mat or thick towel to cushion your head, back, and hips. Raise your legs and bring your knees toward your chest.
- To keep your back and knees from causing undue pressure on your pelvis, do this exercise before going to bed. Get into a 90% lie position.
- As you reach your knees up to your ears, lean back in a rocking way. Like a good workout, you'll strengthen your abs.
- You may make sure to use an elastic pad on your back. Your feet should be almost touching the floor next to you.
