In this video, you will learn how to do a lateral step-up by Dr. Brian Damhoff.

1. Place on foot on a box or step
2. Using the leg on the box, push through the foot to lift yourself up to the top position
3. Then return to the bottom position You can use the bottom leg for support but try to minimally use it.

You want the knee of the leg on the box to line up vertically with the ankle as best as you can when performing the exercise and try not to let that knee collapse in or out. Make sure that you keep your foot on that box pressed flat into the ground which can be one of the tougher aspects of the exercise. The lateral step-up is a great exercise for runners to work in the coronal plane.
