New York winters are long. And those Manhattan-Brooklyn commutes can get unpleasant when we’re all smooshed in with our down coats, avoiding that one person who looks like they have the flu. But one thing that’s not a bummer is the free fitness class you can take advantage of to break up your weeknights. Wait out that evening commuter rush back to BK and enjoy a free yoga class on Thursday in Bryant Park, hosted by CorePower Yoga. Housed in the glass overlook above the skating rink, make sure to register in advance. Signing up DOES guarantee you a spot, but show up at 5:50 pm before the waitlist opens up (class begins at 6 pm). BYO mat.
