This is at 100kg.
I think my hips are rising too quickly and the weight may be going slightly on to my toes.
Also, are my hips too high?
Hips are fine where they are, but they rise too quickly, you’re not pulling back enough (shoulders are not over the bar), and your low back is doing most of the work.
Keep your butt where it is when you start the lift, pull back, and position your shoulder over the bar at the start.
Flex the fuck out of your hamstrings to initiate the pull, then your glutes to finish it.
