Anchor a band to a high point (above your head) and stand sideways to it. Hold the handles in one hand, using a neutral grip, with your arm extended straight down by your side. Contract your obliques to bend sideways, pushing your arm straight down toward the floor. Go down as far as you can (your hand ending up slightly above knee level or so), and hold this position for a second as you contract your oblique muscles as hard as possible. Slowly allow your torso to return to the full upright position. Complete all reps on one side, then repeat on the other side.
