two sideyards, and some front yard, including removing weeds, digging and moving some soil, paving limestone screening and stones, repairing grading, interlocking bricks and paving stones, buying, unloading and moving all materials from the car or driveway to back yard and side yards manually (about 300 bags* 18kg of limestone and stones, plus half cubic yard of river stones, hundreds pieces of bricks, 99% of all the work were done by myself - a small size lady, in a summer ). But I believe I can not do that much heavy work anymore like two years ago. Recently I moved around some leftover materials (about 18Kg* 10 bags plus about 50 pieces of bricks *2 times) in one day, I felt tired and some back pain. I am getting old and I have to pay attention to prevent myself from injury and overload now. But currently I am still ok to move small size car's tires. 😁
