Briana Peterson

I have been a fitness coach for over twelve years and continue to find great joy helping clients reach their goals.
After attending college at KU, I discovered my passion for individual and group training at the Cooper Institute. I trained groups outdoors on the hill at KU and learned a lot about using body weight in creative ways. I would use our surroundings for our entire workout! I’ll never look at a bench the same way....
I use this creativity to construct full body multi joint moves that challenge the brain and work the body to create a metabolic boost. I work hard to make every move target as many muscles as possible. You will leave with a good sweat and every muscle worked. Did you know sweat is best form of detoxification? Now you do.

My goal for every client is to get to a place of consistency. I create a plan with each client to meet their individual goals in their individual ways. I would love to help you whether you are a beginner looking to find a fun workout or a fitness veteran who needs some new motivation or direction.
Facts about me:
I have two little girls and a wonderful husband who doesn’t stretch as much as I suggest.
I graduated from KU with a degree in psychology and am certified through ACSM and The Cooper Institute.
I love Netflix and chocolate.

I am an avid outdoorsman, whether its hiking or hunting I just love to be outside enjoying what nature has to offer. I have a passion for health and fitness, and believe that in order to live the best life that you possibly can, you have to fuel and treat your body in the correct manner. I love helping people reach their fitness goals, whether it be losing a little bit of weight, putting 20 lbs on their squat max, or getting ready for an upcoming sporting season.

Caleb Campbell

Caleb recently graduated from California State University, Long Beach with a Masters in Kinesiology, and a focus in Sport and Exercise Psychology. During that time, he completed an independent study that gave him practical experience as an Exercise Mental Performance Coach for the senior members and coaches at the LifFit center on campus. He also published and presented a thesis study at the 2018 *NASPSPA conference that supports the notion that increased confidence in a proxy-agent (Personal or Group Trainer), and increased confidence in the ability to self-regulate (behaviors, thoughts, emotions), are both positively associated with long-term exercise adherence. The study also was the first to identify specific mental techniques that people of various ages and stage of change would be most interested in learning and would be of most value to them. Caleb has also been physically training individuals and groups for more than a year now, developing creative and effective workout routines. Simply put, Caleb knows what it takes to get you to your goals, not just physically, but mentally as well!

Caleb’s passion and teaching style revolve around taking you to the next level and increasing your confidence, by developing safe and effective workout routines with specific performance feedback. Caleb believes optimal life-satisfaction comes from proper life balance and working hard towards your personal values. “As a new father, I comprehend now more than ever how important it is to value health.” Whether the goal is to help you improve your balance and mobility, or to improve your strength and endurance, your goals are important! Being physically active on a regular basis should be an enjoyable part of your lifestyle and who you are! Caleb also loves sharing good music, art, good local food and crafts, and a beautiful scenery with his loved ones and friends!
