Can't find the broken fanjo club - advice pls

[CupoTeap]

So I have two prolapses was offered mesh surgery years ago but didn't feel it was worth it. With lockdown and work from home my exercise is now zero. I'm starting to feel like it's have a serious effect on my already lack of core muscles but what can I do? I get back pain if standing for any period of time. What options are open to me? Thx
