I think I've super dumb for the 12+ years I've been squatting.
My progress has always been hampered by SI joint issues.
I've always forcefully locked my hips out at the top of the squat squeezing my glutes, even at the start squeezing my glutes hard before descending. Is this wrong?
I just did a set without doing this and it felt a lot better and my core felt a lot more engaged. I suspect this is what has been ruining my SI joint for years?
How are other people completing the top of a squat?
