I've now done both and I'm hoping to do them each once a week as they focus on different things. Yoga Relax is really for when you want to relax and focus on flexibility/stretching. Great for following a tough workout. Yoga Max has tougher poses that are held longer for strength. Both are good for flexibility, but Yoga Relax is much better for that if it's your goal. Both workouts have balance poses with Yoga Max having more strenuous ones. I really like the music in these and Cathe shows modifications for a lot of the poses for those who aren't as flexible.
