I've wondered this many times, and during training tonight and setting a new PR for Barbell rows I thought I'm gonna ask everyone's take on it here. Now I know the obvious ones such as having sex, adrenalin rush's such as driving supercars/sky diving are contenders etc but I think personally for me that brief window of euphoria & personal satisfaction of achieving a weight I've never ever done in my life before whether it be 30 mins or possibly all night and into the next day after if I'm lucky just can't be topped. How much of a High does everyone else get?
