Who the hell has 3+ hours every day to do ANYTHING once they're out of college, and especially if they're in a relationship or have a family?
That's not even close to 10000 steps. 5 miles is about 10000 steps. You would need to run a 10k every day and then some to hit 15000 steps. But a 5k a day is a great goal for everyone.
Well.. it varies a bit. I actually just did a 9k run, was 51 minutes, and just under 10k steps.
So if you ran on a lunch hour (know lots of people who did this, when I worked an office job) then you'll pick up the other 5k steps just doing regular day-to-day stuff, I would think. Then again you sort of need a shower facility available to pull this off.
I imagine it seems pretty hard if you are one of those folks who drives in from the suburbs, from a garage, into another garage at work.
Myself, I have to get my run / hike / whatever exercise in first thing in the morning. If I let it go, I might run at noon, but after that my willpower just falls apart
Some of you have probably hit 10k steps at PAX or Comic-con, or an amusement park, and not realized it.
