If you're in the US and looking for a live (not pre-recorded) online yoga class, Namho Yogis is worth a look. Instructors are Yoga Alliance-certified and trained in Rishikesh, India, and classes run across EST, CST, and PST so scheduling isn't the barrier it usually is. Small group, private, and family sessions are all available, with a free trial to start. More info at namhoyogis.com.
