Everyone should include lower ab workouts in their regular exercise program. Strong lower abdominal muscles can help with your back health as well as improve your posture. Lower ab workouts can also make you look and feel better.

Pelvic Tilt
The pelvic tilt is a classic lower stomach muscle exercise. Lie down on the floor on your back. Bend your knees and place your feet flat on the grown. Pull your abdominal muscles down and in while tightening the muscles in your butt. You should feel your pelvis tilt and the small of your back should start to flatten to the ground.

Variation: Bend your knees and put your feet flat on the ground. Your arms should be on the floor next to your sides. Roll your knees up towards your head, keeping the small of your back on the floor. While you will need the muscles in your butt to do this exercise, concentrate on using your abdominal muscles as much as possible or you won’t get as much abdominal benefits as you should.

Leg Raises
Leg raises are a terrific lower abdomen muscle exercise. Get on the floor and lie on your back with your legs straight out and your arms at your side. Slowly lift your legs straight up while keeping your back on the ground, using the muscles in your stomach and your hip flexors. Slowly let your legs return towards the floor without actually touching the ground. Repeat.

Variation: Lie on the ground as if you were going to do leg raises except put your arms down flat behind your head. Bring both your legs and arms up at the same time as straight as possible. Repeat.

Bicycle
You can bicycle on your back. Lie down and put your hands and arms next to your sides. Then, bring your legs up a couple of inches off of the ground. Start bicycling your legs in circles. Alternate rounds of clockwise and counterclockwise cycling. You might be more comfortable if you put your hands palm down under your buttocks.
