Cycle Bar
Where: Park Slope
Why: Whenever you hear "I'm So Excited", you instantly think about getting on a bike. Classes at this indoor-cycling gym range from beginner to competitive-triathlete difficulty—and with three different durations, there are more than enough options too keep you on your toes while your cycle away (and burn 400-600 calories per 45 minutes!). To make the biking a little easier on your post-Holiday self, Cycle Bar offers complimentary shoes, towels and water refills, so all you have to do is jump on and ride into the sunset...
The Deal: Since Cycle Bar is a pay-as-you-go venture (no membership fees!), they are offering discounts on their various class passes. If you purchase a 20 class pass, each ride will set you back $22 per ride (a savings of $40). If you're ready to get totally committed, a 30 class pass will run $21 per class (a savings of $60).
