The former tight end works out three to four times a week, but sometimes twice a day. His routine includes weight training and CrossFit.Here's what he said:"My workout routine isn’t quite as rigorous as when I played, but I try to get exercise at least three or four times each week. And a couple days a week, I try to get two workouts in."He continued:"I’ll do free weights and then allow myself to get some rest, hang with my dogs, and eat. Then I’ll come back and do CrossFit. I still like to feel strong, so I’ll do bench, incline, and dumbbells. I also like the movement and the cardiovascular workout I get with CrossFit, so I’ll do kettlebells, row machine, bikes. I don’t want to get bored or stagnant, so I’m always trying to mix things up and confuse my body."It's no wonder he has this physique as he clearly works for it. It takes an intense amount of dedication to maintain a body like that, but he is proof that it's possible, even at 54 years old.If you use any of the above quotes, please credit GQ Magazine and H/T Sportskeeda
