Crouch slightly next to the right side of a bench. Step onto the bench with your left foot with enough room so that you can also step on with your right foot. As soon as you place your left foot onto the bench, you will hop, then place your right foot on the bench while the left foot comes down to the floor on the left side of the bench. Repeat movement so that you end up on the right side of the bench again.

This is a rapid movement in which you be moving constantly. If you want an extra pump, you can pulse the movement when you briefly plant your foot on the floor, just like I do in the video. If you choose to do this in double time, you will get a much more intense workout and will no doubt be out of breath!
