Readers: I don't mean to brag, but I've run on a lot of treadmills. While most are fine and get the job done, none have simulated the feeling of running outdoors ... until now. I was at the gym yesterday because it had snowed and running outside was too much of a hassle. As I headed to the standard machines, I noticed a new, curved treadmill. No one was using it, so I decided to give it a try. I stepped on the tread and it moved without having to hit any buttons. So I started running and almost fell on my face--I had to grab the sides for balance. The tread is on rollers (later learned ball bearings) and it takes some getting used to. But once you do, it's just like running outdoors. You can speed up or slow down as you need and it's definitely a workout.

And then buy me one (Spoiler Alert: Sticker Shock!):
