As a Zumba instructor, Diana Blandon saw how much people enjoyed burning calories while swiveling their hips to the Latin-inspired beats, so she decided to open her own Zumba studio. She recruited a team of certified instructors and decked the studio walls in yellow and purple to complement the high-energy classes.

Less than a year later, her studio's grown faster than she ever thought it would. "I'm actually looking for something bigger," she says. "Every [class], I'm getting more people."

In addition to adult classes, Diana hosts kids Zumbatomic classes, leading wee ones in games, dancing, and exciting exercises—welcoming their parents to join in and then stay for the adult class afterward. Her instructors also offer a weekly yoga class and dance lessons in Latin styles such as salsa and merengue.
