"Now, a lot of people, as soon as they see a little butt wink, they instantly think it’s a horrible thing. But you need to ask when it occurs. If it only happens at the very bottom of the squat, it’s probably not as bad as most people think.
If it’s excessive and starts early in the descent, it could cause an injury down the road. If it’s right at the bottom and occurs in a person without a history of back pain, it’s probably not that big a deal."
