Olympic Speedskater Allison Baver's Lower-Body Workout
Tighten and tone your core, hips, thighs, and glutes with this one routine.
This exercise targets your calves and shins, but your quads, hamstrings, and glutes are all engaged.
How to do it: Stand with your feet shoulder-width apart. Without pitching your upper body forward, bend your knees about 45-degrees. Maintain this position as you rise up onto the balls of your feet and lower back down, moving only your ankles. Continue this movement for 30 seconds.
Variations: Angle your knees in or out to really target your inner/outer calf muscles.
