What can a mfer do for exercise?

Swimming is no go because the nearest pool is even further. Running is off the table because of a bad injury I had a long time ago (knees and hip are fucked) and cycling is a thing but my bike is all fucked up and the bike shops around here charge a fortune and I tried repairing it myself based on diy youtube videos but ended up damaging it more.

Walking feels like it's not good enough and I don't really have enough room at home for doing most bodyweight exercises or for home equipment (also too expensive). With winter coming up doing exercises outside won't be impossible but I live in canadia so it'll be a fucking pain in the ass.

Any suggestions fit comrades?
