Hey guys, thanks for the replies.
Couple of quick questions again! With the knee straps, I only bought them based on the article on this site about protecting your knees... Although you're argument is strong, is it deffo bad to wear them?
With the adding of poundage, I understand what you're saying, but the 5x5 stronglifts program is recognised and generally respected. The advantage of the regular poundage is you can see where you're going. Although obviously if it's going to bugger my knees it's not worth it. Is there no way of keeping to a regular pooundage schedule without doing my knees in?
Essentially though, having read your replies and other articles on squating, there is no way of telling what the problem could possibly be. I've read so many technical things, but I don't see anyway I can workout which muscles are weak etc...
I'll video record my squating on Monday and post that, so hopefully you guys will be able to say "your knees are doign XYZ, which indicates that XYZ muslce is weak, which means you need to do this exercise".
My other option is to find a personal trainer, but the ones I'ev met wouldn't have a clue about the level of detail you're talking about.
Can you tell a muslce imbalance by looking at the muscles?! Like, I think the muscles on the inside of my leg look quite big compared to the outer? Guess you'll see this on the video...
Thanks again for all your help,
