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

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 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.

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.
