Crunch has put together two yoga workouts that work well for beginners and beyond. Both are taught by Sarah Ivanhoe, a calming yet energetic (for yoga) instructor. These are non-mystical yoga tapes, which is nice if you haven't done yoga before. No meditation or cosmic anything. She teaches a group class, and some modifications are shown by class members.
The Joy of Yoga is a well planned workout that is a great intro to yoga, or a nice cooldown after a longer cardio or weight workout. It is relaxing and energizing, so you can do it any time of day.
Fat Burning Yoga is tougher, more like a high beginner workout. It is not so tough that one should be wiped afterwards, but one will definitely feel worked out. The pace moves, but not too quickly. I don't know how much Fat-burning this really accomplishes, but it will definitly burn some calories, and work out kinks at the same time.
The DVD interface is well planned, and it is very easy to go through each ot the two programs as written. They are also broken into chapters, so mixing between the two is possible, as it putting together a long yoga workout.
