Ever notice that it's nearly impossible to sprint at max speed on a treadmill?
This week I wrote about how refrigerator design reflects (and influences) what we eat. Well, so too with our gyms. The rows and rows of treadmills and ellipticals are a sign of our chronic cardio habit — and the treadmill itself reinforces the habit by making it hard to do anything other than jog in a straight line at a moderate pace. Spend too many years in a gym and you almost forget that sprinting is even an option.
I actually sprint on a treadmill sometimes. Other people in the gym get nervous because nobody ever sprints on a treadmill. There must be rules against such a thing! They get worried that I'll wipe out. And I do hold back just a little, just in case I don't find the Stop button on the first try. (But only a little.)
Probably better to just go to the park and do some sprints. Of course, I rather enjoy blasting the zombie joggers out of their treadmill stupor.
