8 Week Excerise Class??

This past Sunday, I headed off to the gym for a workout. Sunday is not my normal workout day, but the mood struck so off I went. When I arrived, I remembered that there was a new workout class on Sunday afternoon and thought I would check it out. This particular class was advertised as a combination of yoga, tai chi, pilates workout. Okay I do yoga and pilates regularly. I thought how much different could it be. I found out that each pose was held for 8 counts and then you move to the next. The problem with this is that the teacher gave very little instruction cues on how the pose should be done. I found it difficult to follow the class and also that when looking around that I was not holding arms correctly or having my feet in the proper position. After the class, I mentioned the lack of cues to the teacher. I was informed that with only 8 counts per pose, she did not have time to give very many instructions. I see this being a time problem, but where is the teaching in this type of class. Also, I wondered about how effective or harmful doing poses incorrectly could be. I for one had a very sore knee the next day. I have since find out that this is a class taught using a script and doing the same routine for 8 weeks. At the end of 8 weeks, the instructor learns and then teaches the class a new routine for the next 8 weeks. I have decided that this is not for me and will stick to my regular yoga class where every class is different and continuous cues are given throughout the class.
