Our user asked: "Hello, I had a concern. First off, let me say that the knee problem I am trying to correct is Patellar Subluxation, I am doing a strengthening program from a phycsical therapist and am currently working on flexibiity as well. Now, one exercise that I have been doing is a sing leg press on the Paramount Leg Press machine. I notice that as I reach the end of my set, my leg gets a little exhausted and starts to wobble, mostly inward. I have experienced no pain thankfully, but am concerned about this. Should I keep my knee as still as possible? and do you think that I can pontentially worsen my subluxating knee cap in result of my knees wobbling. I appreciate your time and effort, and I look forward to hearing from you! thanks!"
