Work Your Legs and Core in One Killer Workout

Take 30 minutes to build stronger legs while toning your core. The first 20 minutes of this workout are about standing moves, like lunges and squats with rotation, to target your legs and activate your core. We throw in some heart-pumping cardio moves, like sumo squat jumps and side skaters, to increase your calorie burn before the final floor circuit, which focuses on your backside. Grab a pair of medium free weights, press play, and get ready to burn it up!
