The journey from boy to man is fraught with danger.
First you have to eat, like, a LOT because you keep growing. Sometimes you come home from school taller then when you left that same morning.
Secondly, you have to turn your body into some kind of temple, apparently.
This requires a lot of effort and will mean that on a Sunday you need to be out of your bed BEFORE 9am. This shit is not for lightweights.
You may get stinky ‘pits and your hamstrings will hurt like a b*****d, but it will all be worth it when you start to look ‘hench’.
