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.

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

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.

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.

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.

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

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.
