On the muscle thing. Many times totally buff dudes where completely flailed by noon doing stuff like placing concrete, packing wood or scampering around in the bush setting chokers.
It's one thing to statically lift weight and admire yourself in front of a mirror and another to actually have the stamina to last all day doing something meaningful. Takes a lot of energy to move a mass of muscle.

I like hot stuff but I've lived in the north for too long so not so hot now. I love Mexican style food, just not too hot.
