You might want to "relearn" how to squat dude.
get a broom stick, hold it as high over your head as you can, spread your feet out about shoulder width, squat down until your ass hits your legs, or some of that really long grass that people keep talking about.
practice doing this about 100 times a day. That's right, 100 overhead broomstick squats a day.
Odds are, you're gonna fall over and get nowhere near close to the ground the first few times you try this. Then eventually you'll get the flexibility you need to get your ass to the ground.
If you're a POWERLIFTER (nice shoes by the way, and no, we don't know your bodyfat) then you should start doing box squats after you get your range of motion up to par. Build a box that you can sit on so that your ass is between parallel and maybe a half inch below parallel. Start box squatting. Get that feeling of SITTING BACK onto the box.
Your range of motion issues should be fixed after a month with a broomstick, and a box.
