The people who get the numbness the worst have higher water retention and bodyfat than those who don't.
At 215-218 where I peaked, the numbness and stiffness were nearly unbearable. At 203 where I am now (with almost complete 6 pack) the numbness is mostly gone, just some stiffness left. Once I'm ripped in the 180's, there is no numbness, just weird knuckle sensation.
