Sorry I probably didn't explain that one well enough. I always stress deadlifts as being back exercise, too!
I didn't as such squat the weight up, I always used my back, lifting from a hips raised position...but I used to start in an ATG squatting position simply to build momentum with a big hip raise, before lifting weight off the ground with my back.
The problem with this, is that it resulted in a bit too much back rounding for my liking, because my lower back would curve as I raised my hips. It also meant my arms started off fairly slackened, and that my legs had to do extra work because of the hip raise every rep. This movement worked for me, but it started presenting a bit of pain as I got closer to the 200kg goal.
But now that I'm starting the movement already in the hips raised position, I can focus on lifting with a tighter/straighter lower back and my arms straight. Feeling good so far, just took some getting used to, swapping from one starting position to another.
