- I'm not convinced you can categorically make this statement about workout
- efficiency. I keep good bearings in my skates. Here in Boulder, I can
- definitely get a good workout going both uphill and downhill on the Boulder
- Creek Trail. The grade is typically somewhere between .5% and 2%. Clearly, I'm
- going faster when going downhill. However, since air resistance goes up as the
- cube of velocity, it's not *that* much faster.

- Why do you think that one is getting "more exercise with the lousy bearings?"
