Mustrum_Ridcully said:As you would in D&D - most people in these worls are non-elite NPCs, and only get 3 x 11 and 3 x 10, or, in 3.5 sometimes this new non-elite array.
Most athlets like you describe probably would have to rely on skill ranks and feats (like athletic, acrobatic, skill focus).
And if you look at these atlethes, you will always note that their muscles don`t look weak, even if not all will look like Arnies.
In D&D terms, Arnie would still be a naturally better climber, swimmer, and fighter just by virtue of his higher strength. As has been proven time and time again in real fighting matches, Strength is not the big determining factor in winning a fight.
