Lumpini Park Gym, Bangkok, Thailand

Lumpini Park, the central green space of Bangkok, features three outdoor weightlifting areas. Like other free exercise areas, the equipment is very basic – built to survive the elements and constant use. More than weights, however, Lumpini also features an amazing array of free daily fitness dance groups. For the more refined, there are also ballroom-dancing lessons every Sunday evening. Bonus: There's a healthy population of monitor lizards within the park to keep you company while you get fit.
