Why do you workout every day?

I've been training this morning, Why are you working out every day? why do you need to suffer every day doing exercise? Well, it's a question of chemistry. I read that when you push yourself doing exercise till the moment you feel pain, your body starts to produce endorphins to cover that pain., which is one of the four happiness hormones. That's why I'm doing exercise, to be automatically happier.

Es una buena entrada, entiendo todo. Sin pensar mucho, es dificil cambiar mucho aunque no es fluidez.
