If you need a little extra incentive to hit the gym on a random Monday or Wednesday night, how about doing your workout in the middle of a garden overlooking the Manhattan skyline at sunset? Whoever thought of having weekly yoga and pilates classes at the Brooklyn Grange’s urban rooftop farm at the Navy Yard is a genius in our book. Midweek stretching and relaxation on a herb-scented patio with an awesome view sounds like the ideal way to wind down and put whatever happened at the office far behind you. The classes, which start at 6:30pm, are for all levels, though you are required to bring your own mat, water and photo ID. You’ll need to sign up and buy a $15 ticket in advance in order to get into the facility, but attendees are encouraged to show up a little early to check out the farm.
