Skaters

Place cones out front (optional). Start from standing, lean forward and step your left leg behind you and to the right so your thighs cross, bending both knees as if you were skating. Leap to the side and bring the opposite leg behind you, only tapping your toe to the ground. Immediately jump back to the other direction and continue alternating perform as many reps as specified.

Use your arms for momentum and to maintain balance. Keep your knees bent and stay as low as possible to really work your quads.
