Now consider two individuals, one with perfect health, the other not. Put both on an exercise regimen, the one with perfect health has the potential to reach the best possible fitness, while the other has a lesser potential. The point is that the one with less-than-perfect health cannot possibly reach the same fitness level as the guy with perfect health, because his potential - health - is less.
