I am not very flexible. What should I do if I cannot do a pose?
Unlike dance or acrobatics, the most important thing is how the pose feels on the inside. If the instructor sees that you are having difficulty with the posture, she/he will offer you modifications or an alternative pose. Do whatever you need for your body to feel comfortable during class. Even if you just need to lie down and rest for a while, then that is 100% okay. Remember that there is no such thing as being “good” at Yoga or Pilates. It is only important that you walk out of a class feeling better than when you walked in.
