went to the chiropractor today..been getting severe back pumps during deadlifts and back in general...anyway he had me squeeze some sort of device and it measured how many lbs of pressure i was putting out..The thing that was weird was first off he said my grip is alot weaker then wheat it should be for my arm size..he says for my age range its above normal, but for my arm size (18+) it's sub par..and the other weird thing about it was my left arm is stronger than my right (i'm a righty) he thought that was strange..he said my right arm should be 15% stronger, its not...what do you guys think about all this??
