The Night Workout Guaranteed to Knock You Out and Build a Better Body

This may look a little like you're running in place with exaggerated leg movements, and it kind of is, but it's also a squat, shuffle to both sides, and total-body movement that will engage every muscle if you do it properly. Watch your speed to make sure you're doing it right!

• Start in an athletic squat position. Take a few short shuffle steps to the left, about the distance of your mat.
• When you reach the edge of your mat, pause, bringing your inside knee up to waist level.
• Set your feet down and repeat the motion to the right, lifting your inside leg again. This completes one rep.
