I think its more to do with my left leg being weaker, I'm working on that now with some single leg squats. Left leg is smaller.
In the past my body would shift the weight to the right leg much more when I was struggling at the sticking point. Its not so bad now, but you can still see it as you mentioned.
Also my right leg is slightly shorter so that may be another cause.
My lower back is fairly strong, I was able to deadlift 405 stiff-legged style
My lower back is sore, but I'm also doing romanian deadlifts, reverse hypers on the leg day as well. My lower back gets hit with bent over rows and olympic lifts as wlel so its certainly not weak.
anyway my jelly shoes are hardly ideal as well, once my Adidas weightlifting shoes arrive with the solid base and heels, I'll be better able to see any problems
Yeah 315 can't come soon enough! That was my goal actually by Christmas. Hmm maybe a long shot now, we will see. I'm gonna try some contrast training - do one set of heavy 3-5 reps, then next set at 60% of 1RM , and back to heavy and then light and so on
