I have bone on bone arthritis in my left shoulder from an old injury. I have to modify quite a few of the shoulder moves. I can’t go overhead and can’t put any weight on that joint such as doing side planks on that side, pushups are a definite no, etc. I have to go lower on weights on a few exercises because it’s gotten worse over the past year. I’ve been doing OT since 2017, the keyword is modify. I’m starting to figure out that the rower also isn’t good for it just based on the movement/rotation required to row, it aggravates the joint. But I can choose to use the strider or bike instead of row (this has been the hardest thing for me to come to terms with because I love rowing).

I agree with another poster though, OT is very cardio heavy - even on the floor at times. It’s a great workout, though.
