Just make sure you have the mobility to get into proper position, before you “force” yourself to do them. I personally get more out of rack/block pulls than from the floor, because it kills the momentum I am able to get off the floor, so I rarely pull from the floor unless it’s for speed and even then, most of my pulling is off lower blocks. I also have a long torso, so alot of my volume on lower days are back extensions, heavy abdominal, oblique and hip flexor work. Do you have any idea your ratio of what your pulls off blocks are compared to off the floor? I am 6’5/350 for reference.
