If you are looking for similar low investment stuff. I would think farmer's carry, atlas stone, or kettle bell. I used to work at a boring job and I wouls occasionally pick up some maintenance equipment and set it back down just for that kinda low effort workout vibes.

Basically anything you have around the house could be imrpvised into a tool.

If you have nature nearby you probably have rocks big enough to pick up and carry about. Picking up a big rock and walking around carrying it is a strongman classic.

Kettle bells are cheap and you can do pretty much any gym type exercise with them and they stow into a very limited space easily. So if you sre serious you could do a "starting strength" program with some cheap kettlebells and not be out much of any storage space
