Instead of Riding a Stationary Bike (393–786 calories)...
Try Sharing a Real Bike (286-573 calories*)
If you've already had an opportunity to experience one of the bike-sharing programs in cities like Denver; Washington, DC; Minneapolis; or most recently, New York, then you know that those miles can quickly add up. And while you won't get the same tank-soaking workout as you would in a spinning class, you will get to your destination faster than walking and in a better mood.
*Calories vary with your route, speed and number of pit stops. This is for 60 minutes of city riding, light effort to moderate effort.
