As my training maxes have been increasing on my squat, I've noticed that my knees track well on the way down, but as soon as I start to push out of the hole, my knees cave in, regardless of how much I try to concentrate on keeping them stable.

So far my plan to fix it has been to decrease my training maxes, work at higher reps, and REALLY work on keeping my knees out on my squats. I've also been doing weighted hip thrusts a la Bret Contreras to strengthen my glutes.

Progress is obviously going to be slow to fix this, but the last piece of the puzzle I can think of is to add some assistance work to strengthen my adductors - I just can't think of any good "bang for my buck" exercises to work them.

Anybody have this same problem? What did you do to fix it?

Thanks.
