Roosevelt Island Racquet Club
Located under the 59th Street Bridge, Roosevelt Island Racquet Club has twelve Lee green-clay tennis courts at its year-round indoor facility. Players can burn several hundred calories despite winter's cold and summer's heat in a climate-controlled facility lit by a lighting system that produces no shadows, glares, or vision-affecting laser shows. Tennis pros help players work toward more accurate volleys or more punishing serves, and the exercise warm-up room at the mid-court lounge facilitates sweat production with a treadmill, exercise bikes, and free weights.
