Ehh, I wouldn't call 10% bodybuilder
I agree that most are overweight. Most could use a little more exercise as well. I was just (again) pointing out that commuting on a bike isn't free, even if you discount time.
I still intend to commute on a bike this summer (once we get shower access @ work), purely for the recreational/health benefits - not in an attempt to save money. I will probably alternate home workouts/biking to work to maintain my free time after work.
