Although there are many exercises for upper abdominal muscles, it’s also important to target and strengthen the lower abdominal muscles as well. These simple exercises work to target the deep muscles within the lower abdomen and the pelvic floor. Unlike other exercises, these movements are subtle yet powerful.

Start by lying on your back with your arms outstretched next to you on the floor for balance. Raise your legs with your knees bent. Start simply by holding your legs in the air, at roughly a 90 degree angle from your body. Breath deeply in and out for about 10 breaths.

To increase the strengthening, take a deep breath in and tighten the muscles in your lower abdominal area to bring your legs closer to your head. Breathe normally, but keep your muscles engaged. Try not to use your arms except for balance.

For even deeper strengthening, use the same muscles to pull your legs toward your head until you have lifted your buttocks off the floor. Hold the position to the count of ten, then lower your legs slowly. As you gain strength, increase the number of times you do each exercise and the amount of time you hold each position.
