Hit your YMCA up for an Open Door pass for three months. Your Breast Care nurse will help you with the paperwork (they just have to say the membership will be beneficial to you)
It doesn't give you any dedicated support as such, unless you can find a sympathetic trainer who is interested in your case, but it does give you access. If you blend that with the advice from the cancer council and use the gym as a dedicated space to work on yourself it means something, even if it is a bit random, happens,
I strongly recommend the body balance classes--if you leave your ego at the door and resolve to just wave your arms around of you can't get the sequence of moves right you will be fine. There are certain sequences you shouldn't do immediate post mastectomy-such as planks and some of the salutations, but standing on one leg is very good for you, as is the core strength work.
The YMCA don't advertise the open door program, but if you can't afford a membership they have funding for people in our circumstances.
