Exercise Overview
The Peterson Step Up is a knee-focused strengthening exercise that targets the quadriceps, particularly the vastus medialis obliquus (VMO), while training controlled movement through the knee. It is commonly used to improve patellofemoral mechanics, single-leg stability, and tolerance to stair-related activities in people with knee pain.
