Unless you’re a New Yorker who hates summer, you’re probably trying to maximize your time outdoors, and the thought of spending a sunny hour inside a yoga studio or mostly vacant gym seems like sacrilege. But you have lobster rolls and rosé to burn off. Enter Nike’s Summer of Sport: The athletic brand is offering more than 20 free training sessions per week — the majority of them outdoors — through August 21. Register online for a barre class on the roof of Niketown or a high-intensity interval training workout on the field of gorgeous Pier 40. There’s also running, yoga, and clinics and pick-up games for basketball and soccer, all led by expert coaches and trainers. If you are a summer-hater and you just happen to like free fancy workouts, then we suggest wearing all black, health goth–style.
