Functionally Fit: Isometric Split Squat

Strengthening the quadriceps in the presence of knee pain, chondromalacia or arthritis can be challenging. Often, clients cannot tolerate traditional lunges or loading due to pain in certain parts of knee flexion on descent or extension on ascent. In these cases, isometric strengthening using time under tension can be an effective alternative. This exercise is a progression from the wall sit discussed in the prior column.
