I’ve been curious about how much exercise I’ve been getting on the average. Because I’ve been putting on weight for the past few years, I suspect that it isn’t quite enough—but how much has there been? Most of my exercise comes from riding my bicycle, mostly for commuting but some for utility trips. I’ve been recording my bike odometer readings every few weeks for the past three years, so I can get a decent estimate of how many miles I’ve ridden, though not of the intensity of the riding.
Given the relatively low speeds I go up the hill to work, this translates to about 25 minutes a day of moderate exercise, or just under 3 hours a week, exceeding the Federal recommendation of 150 minutes a week, but not by much.
Looking at the curve more closely, you can see that this past quarter, when I was bike commuting 5 days a week, had about 4.5 miles per day, substantially more than during the 2011–12 academic year, when I was on sabbatical (about 2.6 miles/day). This does not bode well for how much exercise I’ll get after I retire.
