For example, one move is a Warrior 3 pose. In this position you are balanced on one foot while your other leg is parallel to the ground, creating a right angle. You hold this position, but only briefly, and then come down into a squat ... then back up to Warrior 3. You do the reps, then you hold for 15 seconds. Then move on to the next move.
I think yoga should be included in weekly, at least, because it is that flexibility and balance that help you with all of your core and strength and even cardio workouts. They also help reduce the chance of injury when working out or just in your daily routine.
I kind of got the feeling that Jillian doesn't do yoga regularly because she admits to not being all that balanced or flexible as I believe she may be if it were a regular routine. On the one hand, it might help you feel more relaxed to know that even Jillian Michaels can't do it perfectly. But on the other hand, it came off to me that she may not really think yoga is a necessary part of her routine either. It was just my first time doing the program though, so my opinion may change. I love Jillian and her attitude throughout this workout is great. I wish there were a bit more stretching involved, but I can always look to another yoga DVD if I want to stretch throughout the workout.
