I would never hire anyone to be my coach can they tell me how my body is feeling?
You (and many) dont need them (Coaches). You dial in well on your own.
I would never either if I wanted to compete, part of the fun (IMO) would be doing my own prep.
We came up in the 70's (many of us), no such thing really as coaches back then.
We all studied training, supps, nutrition, etc. (We didn't do the BB drugs back then where I came from, didnt have access to them, which is fine).
We trained in our garages, wrote programs, wrote diets, etc.
I was one of the first one's certified working with Dr. Squat, Sal Arria, Tom Platz (ISSA) in early 90's, and it was a breeze honestly, just from studying and reading "The Muscle Books" and doing it on our own. (This stuff is all easy anyways, 2nd nature for many).
I trained some people and wrote diets for them 30 years ago, before I realized I hated dealing w/ people. But it was fun doing the cert with ISSA.
Today, kvnts are spoon-fed & lazy IMO.
