"We also send trained instructors to hospitals to teach classes to those undergoing treatment," she said in an interview.

"We recognize that they may experience nervousness prior to their first class," Tecco said.

McCombie is now back at her job as an executive assistant for an oil company.

"When I started yoga I couldn't even get off the floor by myself. I needed help," she said, referring to her lack of strength . "Now I can do (climb) stairs."
