Just make him exercise. Your not small children that needs to be told what to do. Just start training, with devotion and HARD work u can train any martial art. It tires me a bit that everyone tryes to act really smart when confronting beginners. He don't need to exercise before start training. Martial art IS training. *sigh*
And Pakua is a very powerful MA and gives u alot more HEALTH than the regular external martial art. Anyone can start training Pakua or the Nei Jia (internal arts), old, young, thin, fat, ugly, beautiful or whatever. Just pick a style and Go for it!
All right now, son, I want you to get a good night's rest. And remember, I could murder you while you sleep.
Hey son, I bought you a puppy today after work. But then I killed it and ate it! Hahah, I´m just kidding. I would never buy you a puppy.
