In power yoga, instead of holding poses as you would in traditional yoga, each move directly into the next move, making it an intense aerobic workout.
Viniyoga is most often used as a therapeutic practice for people who are recovering from a surgery or who have suffered injuries. It is a gentle, healing yoga that is tailored to each person’s needs and body type, and evolves with the person as they grow and change.
