Ok. So personal trainers here start out as salaried at $30k per year. They are then expected to get at least 50 client training hours per month within 12 months. They will become commision trainers when they reach 50.
They have waaay more trainers than are needed for all the day except the busy few hours. So most of the time trainers are expected to harrass gym members and try to push them to do a free training session. They could save a lot of money, and likely get more sessions if they would hire a few salespeople who's job is to do that. Trainers are trainers, not salespeople.
Because there are so many trainers trying to get clients, they are always trying to hussle and schmooze the concierge desk to get assigned clients.
