Ready to show that treadmill who's boss? I'll bet you are! After our super cardio session, I want you to rock that lower body! The Stiff Leg Deadlift will give some much needed extra love to our hamstrings, while the pistol squats let us work each side separately for increased strength, flexibility, and mobility. Remember to eat well to replenish your muscles! Your legs have the biggest muscles in your whole body, the glutes!
