Cro Cop - Training for RIZIN (2016)
Everyone develop big muscles, nobody does the small invisible ones. And that is the hardest. This is so true, I was watching people in the gym, they all go for the shape, mass, appearance ( bodybuilding, fitness), but nobody stopped to think about small, internal, invisible muscles. That is the hardest, but it is the best gain you can get for life. It stays with you and really makes a difference even if you are not into sports.
