I used to work with a fat trainer.
He wasn’t a little chunky like he enjoyed a beer or 7 on the weekend — this dude had a belly on him. He was bald with a pudgy face. Every time that he spotted a client on the bench press, he had to contort his body into an awkward anterior pelvic tilt so his belly wouldn’t get in the way.
I worked with this individual early on in my career. Admittedly, I was immature and negative in my thinking. I couldn’t understand why anybody in their right mind would want to train with this guy — he wasn’t particularly attractive and in no way exuded a healthy lifestyle.
