Don't get too hung up on weights as you are developing form in the squat. Don't get me wrong, I feel in order to progress you have to add weight, but at the same time its a fine line. You are doing things the right way, stick with it. Once form becomes second nature you will see your lifts move consistently!

"This is about strength, not getting a 10.0 form score from the Russian judge" Steve Shaw
