  • Isaac Stephens
  • As a youth, I struggled greatly with
    weight and body image. These issues created a desire in me to
    concentrate on nutrition and fitness. My personal challenges drove me
    to start a business that truly focused on training, educating, and
    encouraging clients personally.  I’m always reading and studying how
    to become a better trainer. Over the years I have observed, even
    personally, the importance of proper mechanics of the body. I hold both the Fit Tour and NASM personal training certifications.

In 2015 I received certification in Group Fitness Training from the American Council on Exercise.

  • Kathryn Clardy
  • My entrance into the fitness industry began as a Freshman in college when I discovered the field of Fitness Conditioning and Performance, merging my passion for science with my love for sports. Five years later I am standing with my Master’s degree in Exercise Science, and I am able to successfully provide my clients with satisfying answers when they ask “how/why” doing specific exercises will help their bodies run as efficiently as possible. I have a wide range of experience training high school athletes, professional athletes, and even dads wanting to get off the couch and run their first Spartan Race. I hold the NASM personal training certification, EXOS Sport Performance Specialist and Spartan SGX coach certification. I never stop looking for ways to grow, and I look forward to helping each client achieve his or her unique goals in the most efficient way possible.


At Metrics Fitness Lab, we understand the power of a results-driven workout. Achieving your health and fitness goals is a journey that takes time and navigates many ups and downs – that’s why we utilize My Zone. My Zone is a workout tracker that provides immediate feedback and gratification for a workout well done to keep you focused and motivated.

Working out to the point of exhaustion or crippling soreness doesn’t guarantee you’ll see results. Rather, training for success requires consistency, variety and rest. Each of our high-intensity workouts is assigned its own point value, and each method within the workout is designed to keep your heart rate in a certain range.

With My Zone, you’re able to track your heart rate, calories burned and exertion points earned to ensure you’re training for success. My Zone prevents you from over or underworking while allowing you to focus on a numerical point goal, one session at a time. You can use My Zone outside of Metrics Fitness Lab as well to monitor your workouts wherever you are. Work smarter, and see results sooner.
