andy has been big before. he was in prison. also, if they took these photos immediately after working out, they'll be bigger than they normally are just hanging out. they've got the pump going on. arnold swuartzenegger said the pump feels like cumming. andy's coming all day!
but yeah, if you once had girth or strength, you can 'muscle memory' back to that size and strength fairly quickly vs a newbie lifter starting from scratch. it's like being surprised andy roy can fs air and attributing it to drugs amd not the decades of skating.
