Windshield Wiper

Lying on your back on the floor, lift your feet off the ground and hold your hips and knees at 90-degree angles. With your arms out to the sides for stabilization, rotate your thighs to the right until the outer thigh touches the ground. Keeping the knees together the entire time, rotate them back to the other side.

TIP: There are three difficulty levels with this exercise. The easiest is feet up but close to the hips, the next is feet up with knees at 90 degrees, and the toughest is legs straight up so that the body resembles an “L.”
