Don Brooks knows a thing or two about sculpting fit bodies. The celebrity trainer — who’s worked with Fergie, Josh Duhamel, and all the Kardashian sisters — is also the founder of the Don-A-Matrix training method, which is designed like a four-quarter sports game to challenge the cardio and muscle endurance systems, burn fat, and maximize results. Within each quarter, there are three sets of two different exercises and then a brief period for rest and rehydration. (Khloé posted a booty-lifting version of the workout on her app.)

We chatted with Brooks on his best tips for getting and staying fit, including his favorite things to eat and drink, how to stay motivated, and what move to do to get the booty of your dreams.

On Staying Fit and Healthy: No magic tricks, no gimmicks — Brooks’ tips for staying fit every day are surprisingly easy and doable. He says try to eat healthy more often than not, stay hydrated, get enough sleep, and work your body daily, “even if that means a short bike ride, long walk, or quick jog.”

His Go-To Foods: When it comes to reaching your fitness goals, nutrition and exercise go hand in hand. To properly fuel your body, Brooks is a fan of anything with good proteins, such as eggs or tuna. And since proper hydration helps regulate body temperature and boosts muscle performance, it’s important to have fluids both before and after a workout. Brooks drinks BODYARMOR LYTE sports drink (he’s a spokesperson for the brand) because it’s low-calorie and packed with electrolytes, coconut water, and vitamins such as potassium.

Best Move for Toning and Burning Fat: Brooks recommends a multi-functional movement, such as a push-up into a squat on top of a Bosu ball. “The push-up works the total upper body, arms, chest, and back. And the squats target the lower body. The overall movement even works the core, so you’re getting a full workout.”

Best Move for Toning the Butt: Squats and lunges are best to target your derriere, says Brooks. He advises trying a jump switch lunge — jumping into the air and landing in alternate lunges on a Bosu ball — repeated 20 times. (This move would usually be part of a larger set, like in his Matrix method.) We can’t promise you’ll replicate the famous Kardashian booty, but you’ll definitely feel the burn in your bum.

Biggest Mistake People Make When Working Out: “One big mistake I see often is that people are simply not being prepared to work out. If you want to get the most out of your workout and maximize performance, it helps to come prepared — and that means making sure that you’re properly fueled and hydrated coming into the workout.” This applies to both his celeb and non-celeb clients: Brooks says he’s constantly finding creative ways to get people moving.

Best Advice to Keep People Motivated: Half the battle is showing up. “Just stay with it,” encourages Brooks. “There are going to be times when you want to relax, not work out, give up, whatever it might be — but don’t. It’s important to keep going and work out even when you’re lazy and don’t want to. We all feel that way; it’s just a matter of getting up and getting through it, because you know that you’ll feel better and accomplished afterward.”
