Standing side bend with medicine ball starts with your standing in a firm position, with your shoulders and legs spread and knees locked in. Grab a medicine ball with handles with both your hand; and lift it above your head and push, try not to bend your elbows. Now bend your torso standing straight to the right side and press, bring your arms back to the starting position and press; now bend towards the left, and back to the starting position. And you're standing side bend with medicine ball is complete.
