Hiring a "Fooroo" is like admitting to the bodybuilding world that you can't think for yourself and that you are in dire need of a cheerleading squadron.
Yeah, like baseball players dont have a hitting coach, agents, managers, batting coach, catching coach, personal helpers, advisors. Or any other sport. I guess they do it all themselves too.
Like it or not, sometimes you need another eye to tell you if you look good, with muscularlity, symmetry, conditioning.
Guys like Hany Rambod, Chad Nichols, George Farah, and others are there because people ask for them. And some of them have pretty good track records. If you don't like it, don't use a trainer or an adviser.
