Small amounts of yardwork are very do-able, it'll feel good and you'll get to see results! We rent, but I still do a bit of gardening and things on the rest of the property like the hedge. It's (mostly) enjoyable and quite satisfying. I also find it useful when I'm in a weird headspace. Meditative.
I'm not a big fan of sweating (or the sun) and consequently sometimes do yardwork in the evenings. It's much hotter where you live -- might be a strategy to keep in mind.
Good luck with your endeavor! Enjoy!
