In any competative sport, Id say using "comparison" is a tool for sure.
Body building, power lifting, oly lifting and strongman: all these sports use particular exercises to perform , become stronger at the lifts they are judged on.
Exercising for health on the other hand should not be confused with the above IMO.
Someone exercising for health and a better quality of life should not copy or cherry pick from the above modalities and think it will really make then fitter or healthier.
I think that most of these proffessional athletes are that way in spite of they train rather than because of the way they train.
A "natural" body biulder" could not, should not compare themselves to a drugged bodybiulder, they cannot train the same way.
How do you know they are drugged? You can guess?
Then the discussion gets ugly- it always does.
Having said all that and possibly not making any sense to some anyway a bodybiulder can benefit training like a strong man, power lifter and such just as those could also learn something training like a body builder - at times.
It irritates me when a person who is blessed with natural strength picks on a person whom is genetically challenged.
A great coach has the ability just to look at an individual and tell whether this person is either chicken soup or just chicken s h i t.
