coach is in denial. at 5'6 he needs to be around 168 lbs max (he'll say I haven't been at that weight for 30 years, well duh, you've been roiding all them years), and he'll still look jacked if he's lean there. look at the shorter fighter who are in the 154-168 range.
that denial mode is what causes bad health surprises to hit you like a bus.
I think it’s the addictive personality he has, which is common among bbers and drug addicts, they don’t know when to stop, I recall coach in his early days as a meth addict (maybe he can come on here and confirm it)
Combine with being stubborn, and him being almost 60, it’s not going to end well
Apparently he wants to move up and compete in the heavy weight division
