Why you should do it: "It really focuses on the glute — that's the butt — big time," Warner says.
What to do: Place the jump rope in a circle around you. Stand within the circle, hands clasped together at chest level, squat down to sitting position, then jump up. Land with your legs now outside of the circle, lowering into a squat again.
Jump up again, this time landing with your feet inside the circle where you started. Repeat!
How much to do it: 15 repetitions and three sets.
