The Swiss ball Russian twist improves rotational strength in the midsection. The exercise targets the core, hips, and lower back while also improving stability and balance.
Instructions
Lie with your back on a Swiss ball. Your feet should be flat on the floor with knees bent to 90 degrees and arms extended with hands clasped out in front of your chest.
Rotate your arms and torso to one side while the ball rolls across the back of your shoulders. Stop the rotation when arms are parallel to floor. Pause, and then return to the starting position.
Trainer’s Tips
Make sure your feet stay firmly planted on the ground.
Do not allow the knees to severely cave inward as you rotate.
Do not allow the hips to drop down during the exercise. Squeeze the glutes and hamstrings to keep the hips elevated.
