As I prepare to launch my new arthritis DVD to the general public on May 11, I wanted to give you an effective exercise (included in the actual program) using a simple box to improve quad strength.  In this three part progression, you should begin with a 4 inch box.  The order (easiest to hardest) is:

  1. Posterior box step-down – in this version you lower the whole foot or toe of the non support leg to the floor and then return to upright.  As it gets easier attempt to only lightly touch down and reduce upper body support.
  2. Lateral box step-down – in this version you still keep the knee in line or behind the toes and lower the non support leg’s heel to the floor and then return to upright.
  3. Anterior box step-down – this is the hardest version because the weight shifts forward taking the knee over the toes (yes this is allowed in this case as it simulates descending stairs) and puts more emphasis on the quad muscle and less on the glutes and hamstrings.  Again, lightly touch the heel to the ground.

In the video below, I will demonstrate how to do all three progressions with light upper body assistance.  Once the knee is strong enough and pain free, eliminate upper body support completely as this will challenge proprioception and stability as well.  Remember to work only in a pain free range of motion.
