About This Workout
Plyo boxes are hot property at the gym right now — these six-inch and taller platforms can make just about any move more heart-pumping or hard-core. "Each rep forces your body to recruit more muscles to either catch air or sink lower into exercises like squats," says trainer Adam Kant, the founder of Intrepid Gym in Hoboken, New Jersey. (No club membership? Use a step or a park bench to get the same effect.) Flip the page to try Kant's incinerating box circuit — aim to do it four times through — and take your body to the next level.
