Hello! Thanks for the post and for sharing your experience.

I would strongly encourage you to incorporate yoga and functional strength training into your routine as both will take your limitations/pain into strong consideration and work with your own body weight (or very light weights) to build strength instead of heavy lifting of some traditional forms of weight training. For cardiovascular health, consider low impact movements such as swimming, NIA, or tai-chi. I hope these help. Let us know how it goes!
