Back Exercises: Abdominal Lift Brace with Marching

The abdominal lift brace with marching makes your lower belly (abdominal) muscles stronger. This helps you keep your pelvis and back stable:

Lie on the floor with both knees bent. Put your feet flat on the floor and your arms by your sides. Tighten your abdominal muscles. Be sure to continue to breathe.
Lift 1 bent knee about 12 to 18 inches from your buttocks, then return it to the floor and lift the other about 12 to 18 inches from your buttocks. Keep your abdominal muscles tight and continue to breathe. These motions should be slow and controlled. Don't let your pelvis rock from side to side.
Repeat 10 times.
