A superior athlete is one who has above average physical skills (strength, agility, and endurance) and is thus more suited for physical competition.
Athlete is a term thrown around very loosely these days. Ronnie Coleman is an athlete? LOL.
And elite athletes mostly are above-average in
one of the physical attributes.
To be a master you cannot be a jack of all trades.
High-level athletes usually are superior in one arena to the exclusion of the others.
Truly "fit" folks usually are those who engage in little bits of everything that modestly condition all the physical attributes.
