For the squat: Stand with your feet shoulder-width apart, toes pointing forward and knees slightly bent. Contract the abs and keep them in, engaged as you slowly bend the knees into a squat position.
Remember to keep knees behind the toes. As you return to the starting position, contract the glutes and hamstrings and lead with your hips, not your chest. Start with 12 repetitions for two sets.

Don't Ignore Your Ankles and Feet

Wright suggests simple exercises like hopping on one foot for 30-second intervals.
An alternative is the box jump. Begin by imagining a 12-inch-square box on the floor. With your feet together begin in one corner and moving in a clockwise direction jump to each corner.
After 30 seconds, switch directions. Work up to two sets of 60-second intervals. For a real sweat fest, make that imaginary box bigger.
