I first wrote the title as TOS vs keeping fit, but plumped for a more positive tone

The first purpose of this thread is to ask for any experiences and opinions regarding exercise whilst suffering from TOS. I don't mean exercise specifically to treat the TOS such as nerve glides and stretches, but any general exercise like cardio, resistance work or yoga.

What have you tried?
What can you do?
What do you avoid?

The second purpose is for me to share my experience, in case it might be of help to any others. I'll start that off in the second post. I intend to share some images, so will need to increase my post count ** first. For some background, I'll also link to my introduction post in the introduction thread as soon as I can do that.
