Ridiculously OT: Bike vs Walking

[geoschmo]

I think that on the basis of which is more exercise, there is no question that walking is the better choice. You get exercise by expending energy. The more energy you expend, the greater benefit to your body. The amount of work you are doing is the same in both instances, the distance you travel. A bike is a machine, and therfore by definition allows you to do the same amount of work expending less energy. Assuming you expend your energy at the same rate, which you control by the briskness of your pace either walking or pedaling, you will use less energy riding. It should be a fairly straightforward mathematical comparison.

However, which one is more enjoyable to you is an important consideration as that is the one you are more likely to continue doing as was previously stated.

But if you've got the extra time, enjoy walking, or just have enough determination to make yourself continue regardless, then walking would give you more exercise.
