This conversation actually took place only feet away from me in the gym.
Personal Trainer: So what kind of equipment have you used in the past?
Client: Mostly free weights.
PT: You should use more machines they utilize more of your stabilizing muscles.
C: Oh yeah?
PT: Yeah and they work the extensor pathway.
Me:(Fighting back vomit) What the fuck? The extensor pathway? Isn't that what you drive over to go to Spokane?
Then they both stared at me like I was the idiot. When did personal trainers resort to just making up random shit to get clients to train with them. I just feel sorry for the people who don't know any better and end up dropping $60/hour to work with this jackass.
