About Us


Get to know us

Hive Fitness Journey (HFJ) was founded by Coach Martin, a seasoned fitness coach with over 8 years of experience. The meaning behind HFJ comes from a collection of ideas of what Coach Martin feels creates a thriving client atmosphere.

Hive embodies a holistic fitness journey, symbolizing unity in pursuit of optimal health – mirroring a hive’s collective effort toward a common goal.

Fitness, characterized by peak performance, endurance, and strength for daily activities, takes on a personalized approach at HFJ.

Journey accommodates diverse goals, from body composition to behavior balance, emphasizing its expansiveness based on individual desires.


Together, they embrace the mantra: "Here For the Journey"

Coach Martin’s clientele spans high school athletes to individuals in their 60s. Our programming is backed by a functional training approach that promotes improved daily movement patterns for overall well-being. We are in no way a CrossFit-style studio. We focus on strength, endurance, and mobility through our interval-style training. In classes, we use a variety of equipment, including but not limited to dumbbells, kettlebells, and resistance bands in our classes.

Our commitment to quality is evident in our small group-setting classes, which cap at 10 clients per session. This allows our certified personal trainers to provide personalized attention to each client’s specific goals, ensuring correct form and technique. The intimate class size also fosters a sense of community, offering the opportunity to build long-lasting relationships.  This is the essence of our unique training setting,  which we call personalized group training due to our custom workouts created based on our active members’ needs. Each workout has an exercise or one that is specific to our clients who take classes.

At HFJ, we see our clients as members and as part of our family. Over half of our clients have chosen to make HFJ their fitness home, with many staying with us for over four years. We are proud to be a welcoming community that invests in your fitness goals and values you as an individual.
