@baker00l I was worried about the class length as well, but there are breaks. I would however recommend that you not plan anything else for the day. Once class was done I found myself mentally exhausted. At the end of the classes I was also a little disappointed. I guess I was hoping for something totally revolutionary, but I am doing what they recommended and it's helping. It may seem simple - do these stretches, take everything slow and build up, but it's worth a shot to try. I was told that most people have some improvement.
