For me, bulking isn't that much of a problem, but for some people like my friend, it would be merely impossible for him to bulk.
He already eats about 10 meals per day. WHich includes pasta, chicken, meat, tuna, bread, whatever the hell else he eats.
And yet he still weighs in around 150 pounds.
It's called there are ecto, endo and meso type of bodies.
Some people have to work even harder to bulk because their metabollism is super super super quick. And in some people, it is very hard to gain weight. It's possible, but it gets expensive.
I mean, it gets expensive for me to eat 6 meals per day.
Most of us beyond the 15-25 year old age have other living expenses, other people to take care of. Food can get expensive, believe me.
But for people like my friend, food would cost a ridiculous amont for them to even gain 10 pounds of FAT, yet alone muscle.
For people like me, we are lucky cause, i usually dont' get fat from just eating a mcdonalds burger but i can gain muscle and weight if i eat right.
While for others, eating a mcdonalds hamburger will pack on a pound in a night. They can bulk,but they have to watch very carefully because they gain weight easily.
And finally there are those people who could eat two cows, a couple of pigs, a few chicken and all the soda and weight gainers they could afford, and yet, they'd still remain around the same weight.
It's very possible, as is anything, but for most people, it's usually not worth it.
