Coach Rebecca demonstrates the exercise of the week. Modified lunge with resistance band. With a resistance band around the thighs, step into a modified lunge. Make sure feet are pointing forward, knees in alignment above the toes (knees not coming in medially or positioned out laterally) and not extending beyond the foot. Arms can be above the head as shown, or out in front of the body. Hold 30-90 seconds, 1-3 reps.
