Fixing your Knees Without Surgery Part 2 - You aren’t technically walking in this position. It’s more like a series of small falls.bent knee is absorbing the shock w/ each step. One pair of (Nordic) walkers is landing on extended legs and their torsos are UPRIGHT. Also SHOULD have "posterior push off" The contraction you are looking for is on the outside of the hip, towards the back. The stronger the gluteus medius, the less you have to lean to perform the move.
