The tried and true method to become extremely strong is the following:
Lift a baby calf and carry it around everyday.
As it grows larger and larger you will become stronger and stronger.
One day it will be a huge, full grown bull weighing over 1000 lbs and you will be carrying it around easily.
At some point you will want to slaughter the bull and eat it.
Then get some barbells or heavy sandbags and carry them around instead.
