Personal trainers of fph... What do fatties do with their memberships? Yeah, i'm really curious about this, i go to the gym regularly, and i'll see fat people will come like once or twice, then never again... my gym usually tries to pressure into a 12 or 18 month contract right away, so does anyone have any experience working in a gym? do fatties literally sign 12 or 18 month contracts, then use it for a week?
