Get rolling with a calorie-burning workout.

Go ahead, call us spinsters.

Thanks to SoulCycle, the fat-melting spinning studio with a cult following, we don't mind. (Chelsea Clinton and Tory Burch are regular riders.)

If you haven't yet put the pedal to the metal with the 45-minute workout, take advantage of this weekend's offer: Spin for free at SoulCycle's brand new Upper East Side location. 

You'll torch 500 to 600 calories and tone your legs, core and arms. (Handlebar push-ups help.) Afterwards, refuel with a fresh-pressed juice from SoulCooler, the new spot's exclusive juice bar. 

Snag a seat starting this Friday. Who says there's no such thing as a free ride?

Schedule of gratis classes: Fri., Sept. 25 at 1PM & 6PM, Sat. Sept. 26 at 5PM, and Sun., Sept. 27 at 5PM, RSVP at (212) 639-1300. (One free class per person.)
