Kneeling Cable Crunch with Alternating Oblique Twists
Begin in a kneeling position with a cable machine or band behind you. Hold the rope attachment or band with both hands and pull it to the front of your forehead. Flex your hips slightly and allow your weight to resist the tension. Now exhale and contract your abdominals to pull the weight downward until your elbows reach your thighs. Rotate your torso to alternate sides during each rep to engage the obliques.
