A master once told me, 'exercise is art'. I thought he was showing off, as if 'my body is a piece of art'. But the more I thought about it, the more I realize the truth in those words.
Art, is a little bit science, and a lot of creativity. Art, is a creation process, much like exercise and training. In order to get good at it, you need some fundamentals, a sense of form, and loads of energy.
Thats the key. Exercise is not a disempowering activity. It's not a punitive measure.
It is energizing. The more energy you put into it, the more that comes back. Kendrick just showed that. All the best Art does that. A song crafted in an isolated booth can light the hearts and mind of a million and in turn absolutely propel the life of the author. Exercise, and training does that too.
Guess the old man was right.
