Weight training is very nice for muscle growth and all, but have you tried cycling as a healthy cardio alternative?

If almost a third of trips are less than a mile I feel like the cars are being overused... I am not dismissing the legitimate reasons like rain or carrying kids, although umbrellas and covered strollers have been invented, but I doubt that contributes much to that statistic. If I were to guess, many of these short trips are to the closest mcdonald's drive-through, but regardless.

If gas prices weren't so low(because the US spread freedom to every oil rich country to ensure that), I am pretty sure these statistics would look a lot different. I am sure the urban planning and missing sidewalks don't help, but if fuel was more expensive there would be a lot more people walking, therefore creating incentive for a change.
