I did a 5/3/1 deload squat session a couple of months ago that was the only time I can recall practically jumping with a bar on my shoulder... didn't do me any harm though I haven't ever damaged my knee (they just creak through old age! )
I've noticed more aches and pains the past few years haha. I splintered the Cartilage in my Knee a few years back so I have problems sometimes when I train Legs.
