Celebrity trainer Gunnar Peterson is no stranger to pet projects. Not only did he help Jennifer Lopez train for her triathlon last Fall, he also teamed up with Molly Sims to help the canine set get some more exercise with the PetFit Challenge. These days he is teaming up with Gatorade to spread the fitness word, which he did at the G Gym during the Sundance Film Festival. Recently, I was able to do a brief interview with him — he is a busy man. More a man of action than words, I went right to the heart of the matter and asked about core work.

FitSugar: Let's get down to business — what is your favorite core exercise?
Gunnar Peterson: I’m a big fan of the wood chop, whether it’s standing with a medicine ball, kneeling with a cable, or on a stability ball with a dumbbell.

FS: If I only have time for one strength training move at the gym, what multitasking move should I do?
GP: Squat with bicep curl and overhead dumbbell press, all in one.

FS: What do you recommend for a post-workout snack, after a 60-minute training session of cardio and strength training?
GP: This is what I would consider perfect eating after a workout: salmon, a yam, broccoli and Gatorade.

FS: Speaking of Gatorade, what is your favorite flavor, and when do you think sports drinks come in handy?
GP: I am a lemon lime lover! The original G (Gatorade) for the original G (Gunnar)! You should drink Gatorade during a vigorous workout and post vigorous workout, sports drinks are best.

FS: Tell us one thing we don’t know about celeb fitness. What is your typical day like? When do you work out?
GP: My typical day starts at 4 a.m. I train before my clients, and I work with seven to nine people between 6 a.m. and 7 p.m. While that may not sound like a great day to some, it’s a great day to me. Celebrities work out a lot harder and a lot more consistently than they’re given credit for. They do what they do as well as they do it in peak condition under a microscope. That’s a tall order to fill.

FS: If we could change one thing to live fitter/healthier lives, what would it be?
GP: Get more sleep.

FS: What do you think of reality weight loss TV shows, like the Biggest Loser? What about Jackie Warner’s Workout?
GP: Any show that motivates people to do more for health and fitness than they’re currently doing is a success in my book.

FS: Any advice for folks making New Year’s resolutions to lose weight?
GP: Don’t make a big deal out of the resolution. Of the three “D’s” involved — decide, discuss, and do — eliminate “discuss.”
