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.

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.

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

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.

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.

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.
