I am less than enthusiastic about exercise, too. But I know if I want to stay in the game into my 70s and 80s I must. You are wise to modify. My mom hired a personal trainer when she was in her 70s and sustained a serious injury because the young trainer didn’t understand the limitations of a 70 year old, and Mom wanted to keep up.

Thanks for sharing your experiences. I am inspired to get off the couch!
