Forgive me - I’m too lazy to do web research on this, so I’m hoping you guys can help me out. When squatting heavy (for me :D) if I’m reaching my limits, after coming down to the bottom position, I feel like I lose my lower back arch and lift with my back a lot more (well, exclusively with my back for a good half foot or so). Sorta like a dodgy good morning since my back must be rounded after I lose the arch. I can’t do it now without weights, so I’m finding it hard to describe. Also, it happens when I’m struggling, so I don’t really have time to analyse what’s going on. I don’t do squats like that picture of Arnie Iron posted a few weeks back. I go down to just below parallel, not all the way down, and I stand with a wide stance, just over 3/4 of the width of my power rack.
Am I setting myself up for injury? Should I just drop the bar onto the spotter bars if I feel I’m losing form? I mean, I can still get the bar up, but I definitely use my back a lot more to do it. Am I describing a common squat form problem? Are my legs too weak to lift so I go and rely on my back instead?
Thanks in advance guys.
