Hey Worker,
My pleasure to be of help. Its not often that I can be.
For the adductors, I just started doing a lot of single leg work–actually Eric Cressey had me start doing a lot of single leg work and its really helped. I wish I would could say I was smart enough to start doing it on my own, but I wasn’t until I started working with him.
I do stuff like reverse lunges, elevated reverse lunges, walking lunges, stepups, etc. Mike Robertson has a good article with lots of variations. They’ve really helped my adductors. And they also hit the VMO I believe.
The only other thing I would say is to be careful with the clicking. I would get it checked out if you can, especially if its feels like the knee is “catching” or even momentarily locking up when clicking. I had that once and it was torn cartilage. I don’t mean to scare you or anything, but it never hurts to be safe.
One other thing I’ve learned from Eric is that if it hurts quit doing it before it gets worse. You can always work around it for a while and still make progress–even if the progress is just fixing imbalances.
If you have any more questions PM me.
Take care
Collin
