Work your lower legs with fitness YouTuber Maddie Lymburner, and this intense, five-minute, dancer-inspired calves challenge. Don't worry! No prior dance experience or equipment is needed for this quick bodyweight workout. Halfway through, you'll be breathing heavy and feeling your leg muscles shaking — it's amazing how these exercises work so fast! If this intense workout isn't hard enough, Lymburner said you could always hold some lightweight dumbbells in your hands. After this workout, ease some of the soreness by stretching your calves, quads, and hamstrings with these leg stretches.
