I'd rather take a beating sometimes than get in that gym every morning. Anyone who gets up that early and says he likes it is a goddamned liar. The only good thing about it is that when I'm finished, I look at myself in the mirror and say, "Jack, you've done it again!

I'm always asking people to do something in their mind [first]. So if they're gonna do one exercise, it would be to ask themselves what they want to change about themselves in the next 12 weeks. Once they solve that, the body will follow.

If you want to change somebody, don't preach to him. Set an example and shut up.

When it comes to health, diet is the Queen, but exercise is the King.

Forget about what you used to do. Don't make those same mistakes again. Everybody says, "Oh the good old days" - the good old days are right this second! This moment controls the next moment.

Your age is the sum total of your physical condition, the condition of your mind, and how you feel.

The most important thing in your life is your health and your body. You can have all the education and you can have millions of dollars in the bank, but if you've got headaches every day, if you're fat and you are out of shape - what good is your money? Your health account and your bank account, build them both up!
