Let's get gritty! Body weight legs, weighted arms, and cardio oh cardio! You burn while you build muscle so that you can burn later that day ;) Love this one! Hits the hips, thighs, buns and biceps, shoulders, and triceps. It's great for releasing some lactic acid from other workouts, but also stands on its own. Go light weights for this session. Yoga mat suggested. Shoes optional.
