Crash a basketball game at the West 4th courts
All professional basketball players are super fit, so there must be something to playing basketball. Be the sixth team member or just pretend you're already part of the game at the West 4th basketball courts. You totally get your social quota for the day by making new friends and sprinting back and forth on the court while dribbling a ball is a tough workout! Warning: you MAY get kicked out.
