A great one for the core. Targeting your Abs, obliques and lower back. Lie on your back with your arms straight out on the floor, either side of your body. Your legs should be straight up towards the ceiling. Twist your hips to the left until your legs slowly lower toward the ground on your left side. Lift your legs and move them back to the right side, rotating the hips to the right as you do so. Keep switching sides, making sure your core is engaged, and your lower back isn’t arching. Windshield wipers require the engagement of several core muscles. The upper and lower abs need to remain engaged as the legs move slowly from left to right, without the torso moving too much. Plus, the obliques — the muscles that run down the side of the body — are also working hard here to keep the torso still throughout the exercise. Oh and let’s not forget the muscles in the lower back, which are also working hard as the hips and legs rotate.
