Sore back and sore butt

I noticed yesterday evening that my lower back was sore, a good sore. Like I worked out hard and now I am sore.
This morning I noticed that my butt is sore.
It all has to be from my yoga class yesterday morning. And I think the Wheel or Upward Bow was the culprit.
So anyone who doesn’t think Yoga is “real” exercise, well, you are wrong! 🙂
