A lift-and-twist motion to strengthen the spine
Twisting moves penetrate deep into your body's core muscles and give your spine more freedom of movement. Perform a twisting crunch like this one to strengthen and shape your side abdominal muscles called the obliques. These muscles add the necessary strength to bend and rotate your spine in everyday activities and sports. To get the most out of the crunch, concentrate on a shoulder-to-hip motion instead of an elbow-to-knee. Remember to keep the entire movement smooth and controlled.
