AC Joint Arthritis, advice much appreciated!

Tuesday just gone I had appointment with shoulder surgeon to discuss X-rays of my right and left shoulder.Right shoulder AC Joint has no more cartilage so bone on bone,left shoulder has a little bit of cartilage left.Im 44 years old and a avid gym goer and cyclist.Im worried that my days of lifting weights is now done,and also getting worried about biking especially uplift days as the pain is pretty bad.Surgeon talked me out of having surgery saying that even though I'm in pain I still have decent range of motion in shoulders so now cortisone injections booked in for February.
I've read that it's not good to have too many of these as they can damage ligaments and tissue,so not sure if it's a good idea just yet.
Anyone here with any experience,how did you manage it, could you still keep active ECT

Any Advice much appreciated 👍
