Wait a minute, you're a dude and you hired a woman for a personal trainer?
That's your first mistake, and I'm not being sexist really, and completely serious. Two different sexes and bodytypes man. That was a bad idea.
That's like me wanting to hit my 400lb bench press this offseason and working out with my girlfriend... prolly not gunna happen, she dont know shit and isnt going to be able to push me or spot me...
Go hire another trainer.
