Endorphin high: Try Rise Nation—a high-intensity sesh that uses VersaClimbers, machines that simulate rock climbing—or Barry’s Bootcamp, where half the class is spent on the treadmill and the other is strength based. Or break out a pair of in-line skates.
Tracking stats: Try Flywheel, an indoor cycling class that shows your rank on a leader board, or Orangetheory Fitness, which includes treadmill work, weights, and rowing machines, plus heart rate monitors that track your energy output on screens.
Goal oriented: Try Epic Hybrid Training, which offers HIIT classes with fun challenges (think monkey bar traverses and rope climbs). Getting ready for an obstacle course race? This class can help.
