Hi I recommend Hatha Yoga which is gentle and stretching, or Pilates. I tried Iyenger yoga too but that was too strenuous for me. Hope this helps and good luck!

I broke my tail bone & I still am uncomfortable when I sit for long periods

I do mine at home and I do the ones that are comfortable. But then once in awhile I do some of the more challenging ones. My balance is my worse issue. I use some of the u tube yoga classes once in awhile but mostly I play calming music and do my own thing. Then I meditate afterwards

If you are taking yoga just find a class that does gentle stretches, stay away from hot yoga, or any advanced classes.
