You can't safely go below where you lose your arch, and losing it above parallel is, wow-- I thought I was inflexible. That is the mother of all butt winks. Another thing: don't depend on mirrors, you need to feel things.

I think if you keep working on bodyweight squats, the actual load of your body will help you develop depth. So squat a lot more, and if you haven't improved markedly in 5 weeks, I'll give you your money back.

I like the front squat also for a lot of reasons-- can you find the right place in the bottom of a bodyweight squat-- ie, can you get to the bottom by whatever means, and then produce a nice position?
