Some guys don't have to work out as hard as other guys do, but if you balance all that together then your longevity is definitely going to be greater. So, I would tell my 20-year-old self not to over-train.

I usually eat anything I want. I'm not a big junk food guy, really.

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.

I think guys overtrain and they burn out. And also just knowing what your body needs. Again, I think rest is really important.

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.

Guys are faster, they're bigger and they're stronger. I think that's probably the main thing. And that's not just in football, I think it's in every sport.

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

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.

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.

The toughest individual I've ever met in my life is Jim Kelly, No. 12.

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.

A lot of times I go to the gym and I see people and they don't know how to work out. There's no routine or anything like that. I saw a guy who I haven't seen in five years and the guy looks the same as he did five years ago.

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

Your diet has to be number one. If you don't eat the right things, it doesn't matter who you are. Sometimes those foods treat people differently.
