Forget spending your time and money at the gym trying to get into shape.
What you need is to start doing some manual labor. Something like these workers whose job is sorting empty beer cases.
They make it look so easy and effortless, but tossing around beer cases like they do and at that speed and accuracy, you need to have some serious strength and stamina. And they have plenty of both.
These Romanian workers have become so good at their job, they are almost like a human sorting machine.
Take a look.
Just don’t offer them a beer after work.
