I was raised on a ranch, my first "paying" job was on a farm moving sprinkler pipes and picking rock. I've been a logger, green chain puller (stacked green sawn lumber), cleaned engine blocks and many other manual labor jobs. Work on the ranch consisted of bucking hay, digging fence post holes, splitting rails and posts, cutting and chopping firewood, repairing and building fence, milking cows (want a vise like grip?), hauling buckets of water and sacks of grain and the list goes on and on.
I have found it interesting and amusing that modern training sessions attempt to duplicate this kind of work and yet miss one very important component, doing it all day long. Light to light as we used to call it.
Two very interesting stories to tell you.
When my brothers and I were early 20's we made a deal with a hold homesteader named Bud. Bud had a grandson that was a city kid, weight lifter and football player. Bud wanted his grandson to work with us so he could pay him some wages, make the strapping young lad earn it. Typically Bud hired a bunch of wrestlers, football players and weight lifters from the city to put up his hay for him and it would take the crew 4 - 6 weeks to do it. Anyone that has put up hay in the summer knows that 60 ton isn't no joke, it's a lot of work in the hot summer sun. The grandson couldn't hang with us at all, he was done within an hour and we went easy on him too. After the anchor slowing us down removed himself from the field, we put up the entire 60 ton of hay in 2 days, one weekend.
Bud was so impressed he asked us if we did firewood to, which we did. 10 cord in half a day.
Just a few short years after that I had an acquaintance that needed help, it was coming onto winter and she didn't have her firewood put up yet. The guy that had agreed to do it had sloughed it off all summer. So I did it for her, 5 cord, cut, hauled, unloaded, split and stacked in one very long brutal day. (I did cheat a little, she had a hydraulic splitter)
Now some key things here to take home. First farmers, ranchers, loggers and such work all day, 8 hours is the minimum and can easily stretch into a 16 or even 20 hour day. Second they don't try to make their work as difficult as possible, they try to make it as easy as possible. Once you repeat something hundreds of times you get a groove for it, you learn how to hit the bale of hay with your knee to get it up on the stack or swing the splitting maul just so to get maximum power without tiring yourself out in five minutes. They don't "train" to work, they just simply work and it's hours of back breaking labor, most of them are arthritic when they get old. Bad shoulders, knees, backs and the list of ailments goes on and on.
If you want to get strong like a farmer here is the short list of what you can work on.
Make sandbags in various sizes, up to 100 or even 150 pounds. When do you need the 150 pounder? When the 100 pounder feels easy, you will know you are ready. Haul them around. Over your shoulder, bear hugging, just keep going until you get tired and you will, find a new way of carrying it that doesn't hurt so bad.
Get some farmers bars, kettlebells or make a contraption that you can load with rocks. Jon Paul had such a contraption, it flat works. Carry it, as far as you can go. Half body weight in each hand is a good first goal to shoot for. Next goal is body weight in each hand. I've done 130 lbs in each and you feel like you're flying when you drop them.
Get a old tire and a sledgehammer, start off with 8 pounds. Better yet volunteer to chop firewood for friends and neighbors. Just go until the stack is done, your fitness level will determine your pace. If you use the tire and hammer method, you'll know when to quit. Just keep pushing until you can go an hour and not feel like you got beat to death by a gang of teenagers.
Grip, grip is the defining characteristic of manual labor types. Do towel hangs for time, thinner towels with a hand on each end is easier. When you can hit a minute, use a thicker towel. After that, use a thin towel and go one hand at a time holding both ends in the same hand.
What happened to me? I moved to the city and got a desk job. Now I have to bust my a#@ to get it all back .......... fun.
