Weight is a poor indicator of condition, and over emphasized because there's not an easier index, but I'll venture that a 250# football player is likely fitter than most people with very favorable BMIs. Proponents of the BMI even had to come up with a category -- the fit fat -- to get around the statistical issues with the system.

IMO, those Clydesdales who take up biking should focus less on the scale, and more on their belt size. This will usually show more progress and be less discouraging than the scale.
