There's been a lot of digging with a shovel and pickaxe, earth-moving with a wheelbarrow, and hauling 100-200lb boulders. (driveway cuts, grade adjustments for water drainage, septic, retaining walls...)

But I also recently rebuilt an old roof, and turned it into a mild climbing+parkour game by not using any ladders. This past month I've gotten quite adept at jumping off a 1-story roof.

There's plans for burying a geothermal ground-loop which will involve digging ~50x10` down to 8', basically digging an in-ground pool by hand, only to fill it back up again.

You can make this stuff as difficult as you want...

Edit: Wanted to mention one of my neighbors has been building underground earthdomes which is very labor-intensive, but has the nice property of turning almost pure labor into thermally ground-coupled housing. Totally unaffected by today's lumber prices for example.

I love the roof and the earth domes.
