If some humans are capable of incredible physical and mental feats, short of having some superior physique, it must mean every human body holds similar potential.
How do we unlock that potential?
Discussion
Imo some people are built differently, phyiscally/mentally and its a bit of genetics lottery.
BUT I think the "unlock" is somewhere in people learing patience and consistency in whatever they choose the pursue.
Commitment
Time, willpower and fear
Literally: mind over matter.
Deliberate practice, training, and applied experienced go a long way. I see / experience this in the realm of long distance running, were one sees the mind try to shut the body down way before the body is actually physically not able to continue. I believe it is within us all to unlock.
