9. Speed Skaters
Speed skaters train lateral power and movement, hitting your glutes and quads with a serious calorie-blasting burn.
Begin in a quarter squat position with one foot slightly behind the other. Leap sideways, pushing up and away with your planted foot and landing on the opposite leg. As you land, swing your other leg behind you, and then reverse the momentum into the next repetition. Repeat for the prescribed time.
10. Box Jumps
Box jumps are a great plyometric exercise to add some extra kick to your calorie-burning circuit.
Stand in front of a plyometric box or bench. Jump up onto the box with both feet, landing softly and standing all the way up at the top. Step back down one foot at a time, or jump back down, then immediately jump up again into the next repetition. Repeat for the prescribed time.
11. Skipping Rope
Skipping rope is an amazing way to quickly burn calories—especially when performed with high intensity.
Begin standing with a jump rope. Skip the ripe using a double or single-leg hop. Find a rhythm, and continue for the target time.
