Don-A-Matrix On Working With The Kardashians, BODYARMOR & Fitness Success

An in-demand personal trainer, Don-A-Matrix has trained a lot of notable celebrities — including Josh Duhamel, Fergie, Will.I.Am and members of the Kardashian family — and professional athletes. The man known as Don Brooks spoke with me on behalf of The Hype about how he wound up becoming a trainer-to-the-stars, his work with the BODYARMOR Sports Drink brand, and things someone looking to get into better shape ought to keep in mind when making lifestyle changes.

More on Don-A-Matrix can be found by following him on Instagram via @donamatrixtraining.

When it comes to successfully training someone to get into better shape, for you, how much of it is diet versus exercise?

Don-A-Matrix: The relationship between diet and exercise is a delicate balance. When I work with someone, it’s important to see their dedication to both their diet and exercise, because both are crucial to improving one’s body. You can have a great workout routine, but if you’re eating the wrong foods, you can’t expect your body to react positively.

Where did the idea of becoming a trainer come from? Were you always serious about fitness?

Don-A-Matrix: I’ve always had a passion for fitness and a drive to stay healthy and in shape. Before I became a certified trainer, I was someone who loved working out and the accomplished feeling that comes afterward. When I moved out to San Diego years ago, I knew I wanted to be a trainer but I couldn’t have imagined where it would take me. It’s been a blessing to do what I love everyday with great clients.

How often do you personally work out? Does any of your exercise come from your training clients?

Don-A-Matrix: I’ll normally workout once-a-day on my own in the early morning — for about an hour — and then I’ll actually be working out with my clients during their sessions. So, realistically, I end up working out at least 2 to 3 times per day, especially if I’m going from one client to another. And every workout will normally last from 45 minutes to a full hour.

People have called you “the Kardashians’ trainer” in press coverage. How do you feel about that?

Don-A-Matrix: I think it’s great. Obviously, the Kardashians have an enormous brand so it’s pretty cool — and helpful for my brand — to be connected with them in that specific space. They’re very easy to work with and have a great attitude at the gym, so it’s a pleasure getting to work with them frequently.

How did the Kardashians first find you?

Don-A-Matrix: I had actually been working out with more entertainers and actors, as compared to athletes, when I first met the Kardashians. At that point, I had been training with Josh Duhamel, Fergie, Will.I.Am, and a few others. They heard my name through mutual connections and were looking for a new trainer to work with at that time.

I have also read that BODYARMOR is your preferred sports drink. What separates BODYARMOR from other sports drinks for you?

Don-A-Matrix: Unlike other sports drinks out there, BODYARMOR contains natural flavors and sweeteners, potassium-packed electrolytes, coconut water, vitamins and nothing artificial. I’m always working out and on-the-go so it’s important that I stay hydrated and fueled throughout the day, and BODYARMOR is perfect for that. BODYARMOR has a LYTE Sports Drink too, which has all the same natural ingredients but has only 20 calories and 3 grams of sugar per serving.

When it comes to dieting, what is your take on cheat days?

Don-A-Matrix: Instead of looking for a full “cheat day,” try to have a cheat meal. That way you’re not sacrificing a full days’ worth of meals that would otherwise be fuel for your body.

When not busy with training, how do you like to spend your free time?

Don-A-Matrix: As I said, I end up working out at least two to three times per day, which doesn’t leave much room for free time. But when I do get those free moments, I love to kick back and relax at home, listen to music, and even cook.

Finally, Don, any last words for the kids?

Don-A-Matrix: Get your mind right and your body ready. There are going to be times when you want to relax, not workout, give-up, whatever it might be — but don’t. It’s important to keep going and workout even when you don’t want to. We all feel that way, it’s just a matter of getting up, motivating yourself and getting through it because you know that you’ll feel better and more accomplished afterwards.
