Squat form check, knee collapse?
5 reps at 110kg, this is a reasonably comfortable weight for me but at about this level and higher I start to feel knee collapse inwards, do people think this level of knee collapse is problematic? Rep 4 especially. How can I combat it, accessories or technique change etc? Absolute max was 122.5kg for 5 but the collapse was there so I have backed the weight off a bit.
Also is this amount of buttwink ok or something I should work on?
Thanks for any other advice or tips!
