Honestly man, this statement is just absurd. To say the gym is useless cause you smoke is just nonsense. I was a smoker for a long time, and I still seen health benefits from working out dedicated non stop.
I was one who was hooked at a young age, and it went into adulthood, I found the essence of health in that time, and the gym was my life, and I still smoked. It wasnt till a few weeks ago that I quit... when my woman became pregnant, there is no way I will smoke at all with a child on the way.
