Russian Twist

Russian twist: Start in sitting with knees bent to 45 degrees and heels on the ground. Slightly draw in your lower abdominals and lean back, keeping back straight. Bring hands together. Rotate your hands and trunk to the side, then to the other side. Maintain lower abdominal engagement. You may add a weight to your hands or lift your feel slightly off the ground to increase the difficulty of this exercise. Alternate 5X to each side.
