Bikram Hot Yoga 305 (CLOSED)

Despite its hidden location in South Miami (think body shops and warehouse spaces), Bikram Hot Yoga has amassed quite the following since opening in 2014. Classes follow the traditional Bikram practice: a series of 26 different poses done over 90 minutes in a room that's been heated to 105°F (!!). Owner and lead instructor Carolina Villalba is partly why students brave the extreme conditions to sweat it out—she's fun, energetic and will make you forget just how hot it really is. The studio also serves as a pop-up training center for other disciplines and fitness instructors, including the likes of celebrity fitspo queen Tracy Anderson.
