Standing on a step, place a barbell on your shoulder (or in front of your shoulders to increase difficulty), lunge backward.

Make sure to keep most of the weight on the FRONT leg, especially when coming back up.

Make sure the back leg is lifted forward when coming back up and does not touch or rest on the step.
