This is how I'd say about my daily life.
I think to start going to the gym is not easy, you need a result otherwise the motivation will die.
That's also a reason why I love my PT, although he makes me feel like dying most of the time, I know it's good for my body and since I started I have changed a lot!!
So yes... from all the miles, sweat and effort you will get more satisfied! ^^
Time to get movin!
