When I was a Costco yesterday, I saw they have the Fit Bit for sale at $94.99. It's usually $100, I've even seen it for $150 so you can save a little if you can get it at Costco. I'm not sure what model they have so if you purchase one make sure you are getting the model you prefer.
Fit Bit is a popular tool that tracks your activity, gives you the ability to sync your stats, see trends and reach your fitness goals. It is a band you can wear on your wrist or attach to your shoe. Research it at fitbit.com. It might be just the tool you need to jumpstart your Spring fitness regimen.
(No, I don't get any remuneration! I just want to share the good price with my friends.)
