Progressive resistance training as a metaphor

Progressive resistant training. The more stress you give to your muscles, the stronger they become. Then I begin to think that all those stress releasing programs are actually making you weaker. If you are giving stress to your physical body, your body is growing and becoming stronger. But if you are relaxing too much, that means you are getting weaker. So we need to think more deeply on this topic, that all these stress release program.

I think the program should be to make your mind strong, more strong, so you can cope up with more stress. Only this is the way to develop, make your mind more powerful. If body is developing then why not mind will also develop. Progressive resistance training, it's a very good word for this.
