You don't use much calories doing that sort of work
Removers & builders & other sorts of tradesman is good depending on what sort of job you're doing for the day. I use to work installing air conditioning, we did a lot of moving around lifting, pretty much lifting and pulling stretching pipes , moving through roofs or underneath houses for hours on end without eating...then having a quick lunch (if we had time) then going straight back to it. Not to mention the hotter it is here the more work we had...so we'd be going up n down on a roof, inside and out, lifting things ontop, bringing them down, bending pipes, wielding pipes in 40+ degree aussie heat for hours & hours without break, besides for lunch for a few minutes if we had time as I said earlier.
Not to mention 98% of the air conditioning units we installed had to be manually lifted and installed into complex area's so we couldn't use any machines to the out-door units which weighed upto 200kilo's...usually 2 or 3 of us at the most would be doing it, it may sound light, but when you're spending 30-45minutes putting it in place holding that weight yah..lol
