Position two cone about two feet apart. Begin standing on one leg and slowly squat down reaching the left hand toward the right cone. Lightly touch the cone at the bottom and return to the full upright position each time. Next, reach the right hand toward the left cone in the same manner. Alternate sides and perform 5-10 repetitions on each side. Repeat for 2-3 sets.
Discourage any excessive valgus or hip internal rotation/adduction during the movement, and watch for overpronation as well. Encourage a slower controlled cadence especially on the descent.
This exercises can be done in front of a mirror to offer visual feedback and kinesthetic feedback can also be used to facilitate the proper movement pattern.
