Zumba

Founded by three Colombian men named Alberto who joined forces in Miami, Zumba is a dance-inspired workout taught at gyms, schools, and yoga studios all over the world. Each instructor is a Zumba Academy-trained entrepreneur in their own right, using a fairly precise formula to host workout sessions—right down to the Latin-infused pop-music soundtrack. Instructors can earn extra by hawking Zumba clothing, shoes, and other merchandise to clients.
