Tracy Fober's Ironmaven post for today was a good example of when a kinetic link does the unexpected and zigs instead of zags. A lateral lunge caused right knee pain. Sometimes hip or ankle stiffness or a genu varum or valgum gives unexpected results. It doesn't mean you give up doing lateral lunges. Tracy's solution was to put him in a stride stance and use pelvic drivers to get from point A to B. In other words, she set her athlete up for success. Simply put, she saw the frontal plane was gunked up, so she used the sagittal & transverse planes to get to the frontal. It would be interesting to see what would happen if the athlete went back to lateral lunges after Tracy's intervention. I'm sure that knee would feel a little better.
