When you are younger you tend to overtrain and you don't realize it because you're so high on adrenaline and stuff.

I was a gym rat and I always thought that was a part of my success.

Guys get injuries and there's a reason why these injuries happen. A lot of time you're going to get your knee injuries and your ankle injuries, but sometimes if a guy's back is hurting it might be because his core isn't balanced with his back.

When I came into the league in '85, the regimen for working out was just basic, and as I got older it became more about the core and keeping your body in balance.

I think that while kids are in college they don't think that fitness and nutrition are really important things. But once they get to the NFL it's a job, and just like any other job you've got to be at your best to a certain point, especially with a job like this. You've got to be fit and you've got to eat the right things.

I think as you get older and things don't work as much as they used to, you've got to have a tendency to do what's right for your body.

There are so many things out there now like these 30-minute workouts. I don't know if they work, but a lot of people have jobs and they don't have time to go to the gym. They can do those little 30-minute workouts they see on TV, or get one of those little portable gyms for their house. I think that's a good start.
