Yoga is hands-down one of the best all-around workouts. The right combination of poses can do everything from strengthen your core [1] and improve your flexibility [2], to relieve stress and muscle soreness [3]. And while there are plenty of studios to choose from, being surrounded by more experienced strangers can be intimidating [4], especially for a beginner. Whether you're still finding your way in this practice, or you simply don't have the time or budget for a class, doing yoga at home can help you tailor your workouts to fit your needs. We've rounded up some of the best yoga videos on YouTube, from beginner flows to workouts that will challenge you to take on more difficult poses.
