On Friday, I had the best yoga class I have attended in years... seriously. I am not sure what made it amazing. I felt powerful and gave it everything I had during class. I also made some significant improvements on my chaturanga. The instructor played opera music during class and jazz during savasana. The pace was perfect. She did lots of adjustments during class. She also had a fun European accent. Is it the instructor that makes the class? Or do you create your own successful class?
