You can be huge and swole on the outside, but if you're still a tiny, insecure peasant on the inside, it's all for naught.
It's not really an optional distinction. Our phyiscality will eventually fade. Proper training will perhaps delay it by 20-30 years, but in the end, we'll all be in the same physically infirm place, whether it's at 60 like most Americans or 70 like most Europeans or 80-90 like some exemplary members of society.
Those who truly benefit are those who used the training to work on their "inner" bodybuilder, to enjoy the journey of self-discovery, and to bring them closer to inner peace.
