My treadmill is dumb. Or maybe I am.
It has no knowledge of my weight, and I can't figure out how to measure heart rate on it (it has a thumb sensor - I get readings like '50 bpm' in the middle of a hard run).
Anyway, I noticed that running a mile at 6mph yields EXACTLY 150 calories on this treadmill. (On a previous treadmill, it was like 165, but oh well. What's 1/3 of an Oreo in the grand scheme of things?).
However, when I run at 7mph, I've noticed it goes a little down. So today I charted the following, all according to my treadmill:
1 mile at 10mph*: 144 calories
1 mile at 8mph*: 147.6 calories
1 mile at 7mph*: 148.4 calories
1 mile at 6mph: 150 calories
1 mile at 3mph: 192 calories.
* I didn't actually do this - I stood on the side and watched it for 1/4 mile
Holy cow: 192 calories for REALLY slow?!? Sorry - I mean walking briskly? Maybe I'll bring in a stationary bike to work and pedal slowly while I'm coding and burn it up. I suppose we should characterize it like this however:
3mph: 576 cal/hour
6mph: 900 cal/hour
7mph: 1038.8 cal/hour
8mph: 1107 cal/hour
10mph: 1440 cal/hour
I just intrigued
