Sweat it out with Fitbit Local, a monthly series of free workouts hosted by fitness leaders from your community.

Happy hour in a bar is great; happy hour in the Boston sunshine is better.

Join Fitbit Ambassador Chad Flahive for an outdoor fitness happy hour designed to boost endorphins and vitamin D, sculpt muscles and shred fat in vibrant Copley Square. All fitness levels welcome! You can even grab a friend or two and work out in true squad style.

Stick around after the workout for a chance to win a Fitbit tracker of your own.
