Just wanted to share a success I've had recently.
I picked up squash in late December after a decade-long hiatus. I thought it would be great cardio, and I enjoy it and had been wanting to get back into it for a while.
Within a month my knees were in pain (patella tendon). Going up or down steps was painful, and so was just bending down to pick something up off the ground. My SLS exercise starting to suffer as well, as my knees would hurt during the exercise, and at times even give out at certain point in the motion. The last match I played in Feb left my knees feeling extra sore for a couple of weeks (it was a particularly long match).
So needless to say, I stopped squash after that.
I continued on with my SLS exercises, being particularly careful on the iM not to aggravate it too much. And without any rehab at all, my knees slowly started to feel better and better. It's now about 5 weeks later and the pain is virtually gone, whether I'm going down stairs or doing SLS, they feel solid and healthy.
So long story short, GST is good for your knees!
I'm hoping to try squash again in the fall and that my legs will be strong enough at that point to handle the impact... we will see...
