Hi Mary, It's a tricky thing offering suggestions for exercises in words over a forum post. There is a lot of room for misinterpretation. You have inspired us to put together a list of common modifications that may apply to several conditions. We will video these and put them up on the exercises page. Please be patient with us, in getting them up, but know that it is on the list of things to do. In them meantime, I suggest you ask the question in the Instructors corner. We have many subscribers like yourself who teach and have similar questions. I think this is a great one to spark a nice exchange. Thank you for your question.
