This yoga fitness flow is a standing pose flow. The center pose is done for balance in the hamstrings. If one side of your body is tighter than the other try moving your head towards that side so that it stretches more. This can be done until the muscles have the same feeling of flexibility on both sides.
The yoga fitness flow starts with a basic standing pose stretch. It is easy to step into this pose from the main yoga pose called Mountain pose or Tadasana.
If you are a yoga teacher you may want to adjust your sequence so that everybody is not facing the opposite way in the class. I never liked teaching a class and sequencing he student to face away from me. Get creative. Adding a few postures to your sequence can keep your students facing forward.
