This exercise is a great way to target the lateral trunk muscles.
- Lie down on one side and place the Pilates ball between your knees. If desired, you can place a small pillow or Pilates ball under your head. Place the arm on top in front of your chest for balance. Keep your hips and shoulders stacked vertically.
- Exhale and lift both legs off of the mat without letting your pelvis tilt forward or backward. Inhale and lower your legs slowly back to the start position.
Repeat 8-12 times, then switch sides.
