Restorative Kripalu-style classes, where you spend most of your time lying on the mat, will burn fewer calories than faster-paced classes of more intense styles like Ashtanga, Vinyasa, or Jivamukti. In these classes, you spend most of the class doing standing postures. If your studio schedule is organized by levels rather than styles, choose the higher number classes such as level two or three. The more you're moving, the more calories you're burning.
