My Approach
My training is highly individual. I have been a trainer for 12 years and those years of experience have taught me that everyone’s needs are different. I do believe in building a solid foundation of quality movement and strength alongside cardiovascular/ cardiorespiratory health. Building our strength and fitness to help maintain our ability to do the things we love for as long as possible is the goal. I also love the performance side of training. Helping athletes with injury prevention and increased performance through building strength, power, and conditioning.

Dustin Price
Dustin Price
Certified Personal Trainer
I love what I do because I enjoy helping those seeking help. I’ve helped clients for 5 and a half years reach numerous goals; losing weight for a wedding, getting stronger at bench press because they made a bet with their friends, get better conditioned for a soccer try out, improve their shoulders range of motion, etc etc. I got into training because I lifted with a friend that got me to join him at a facility but after 2 weeks his membership expired and I just signed a 3 year contract. Because of that, I read as many articles I could on bodybuilding.com to learn what to do and how to do it. After about 5-6 months of lifting 3-6 days a week my body made changes that my co workers start to ask what I was doing, what am I taking, what I’m eating, etc. A few of them started going to the gym with me and I became the one making our workouts and telling them how to do this and that. Fast forward to 7 years later, I made a career change that didn’t workout the way I had hoped so I looked into becoming a personal trainer because I was still lifting and enjoyed my time leading my co workers in the gym.
My Approach
Full body training to increase muscle mass and muscular endurance, with an emphasis of strength training in compound movements (squat, bench, deadlift, overhead press, chin-up). Strength training is more than numbers on the bar, it’s longevity. Building muscle is more than getting in a pump, it’s creating muscle mass to improve metabolism. My approach is to create a program based on the clients needs and abilities to improve their daily lifestyle by getting stronger, building muscle and leaning out.

Why Train with Me?
Because I take pride in what I do and the name I’ve made for myself.

With an occasional brag about how they squat, benched, or deadlifted during their workout.

My Approach
When it comes to training, I like to focus on strength, functionality, and heart health. I believe that everyone benefits from strength training. Increasing total body strength does amazing things for us physically and mentally. After learning the science behind how being active aids in our overall health I knew that this was something I wanted to share and help others with. Keeping our heart and cardiovascular system healthy is extremely important and I like to incorporate different ways to improve it within each workout! As a former athlete, I also understand what it takes to perform better on the field/court. Focusing on sport-specific movements in the weight room directly carries onto the field/court when it is time to enter into competition.
