Pedometer

Walking is pretty much the easiest exercise you can get, and I highly recommend buying a pedometer. Mine is a simple one from the folks at Accusplit.


I like it for several reasons:

• it counts steps, which is something that is equal for everyone (the models that count miles need to be calibrated per user, etc)
• it has a cover so you don't accidentally bump the reset button
• it has a kickass warranty, which is printed on the inside cover, just in case something goes wrong later
• it comes with a little "leash" to attach to your belt loop so in case the pedometer falls off, it's not going far
  

I track my steps every day and try to aim for an average of 10,000 steps a day (over a week). This week I've been not hitting even half that because of the crappy weather, but last Sunday I hit 19k.

It was invaluable when we went on vacation - we walked over 154 miles in 14 days, and seeing those numbers kept us motivated to keep on walking instead of taking the subway.
