The Box Squat is the easiest way to use the dead-stop method with this movement. Use a wider than normal stance, open your knees and squat down until your butt grazes the top of the box. Hold there for a one-count, making sure to stay engaged; then drive up off the box. Use a knee-high box so that your pelvis is tilted forward and your back is arched. A box that’s too low will put your body in an undesirable bottom position, which could lead to injury.
You can also place boxes on the side (see the video below) and squat down to the resting position before driving back upwards again.
