Member of the Month: Dennis Marx

This month we’re profiling our oldest member, Dennis Marx. When he’s not at work as a senior vice president for an investment firm, he’s usually at the 5:30 pm class.


Age: 72 !!!!!

How long have you been doing CrossFit? 3 years

How did you come across CrossFit? Golfing buddy who goes to the Wilmette box.

Many older people are scared to try CrossFit and are sure they can’t do it. You started at age 69! What would you tell those other people?You are only as old as you would be, if you did not know how old you really are” (quote from one of my Harvard business school professors).

I do only what I feel comfortable doing. When in doubt, I take a “senior discount” to the Rx. There is no intimidation from anyone. Our training partners’ culture is one of constant encouragement. And from our technically competent RPE trainers, I have learned that I can measure improvement. I am constantly learning proper postures and techniques that make the movements easier and safer.

What are your favorite movements/lifts? What is your least favorite? Favorite = rope climbing. Least favorite = overhead lunges.

Any recent PRs you want to mention? Toes-to-bar improvement.

What is one fitness/health goal you would like to set for yourself? No single specific goal. Rather, continue my overall health and happiness.

What’s one thing most people don't know about you? Do you have any hidden talents? Unknown: I have been involved with universities in Poland, The Netherlands, and China. My talents are so well hidden they are unknown to me, as well.

How has CrossFit changed your life? I have a whole new wardrobe and a lot less money, due to loss of weight. My golf game has improved as a result of better flexibility.

Why do you keep coming back? I have never met a stranger at RPE. My classmates keep me coming back.

Why CrossFit RPE? Same as above. Also, totally impressed with the technical talents and personal skills of the coaches.
