Single-leg abdominal press variations

To improve your core strength more completely, try variations of the single-leg abdominal press:

• Opposite hand on opposite knee. Push your right hand against your left knee while pulling your knee toward your hand (top illustration). You'll be pushing and pulling across the center of your body. Hold for three deep breaths. Then do the exercise using your other hand and leg.
• Hand on outside of knee. Place your left hand along the side of your left knee (bottom illustration). Use your hand to push your leg inward. At the same time, create resistance by pushing your knee away from the center. Hold for three deep breaths. Then do the exercise using your other hand and leg.
