Jake Katnik,

Fitness Philosophy: I believe that consistency and progression are the main pillars of effective fitness training. I encourage prioritizing gradual improvements over quick fixes to build sustainable strength and endurance. Above all, it is important to listen to your body, adjust workouts accordingly as needed, always strive for proper form, and embrace the journey of becoming a stronger, healthier you.

Fitness Philosophy: I like discussing non-scale victories. Specifically, I remind clients about the tasks they use to struggle with and show them how they have improved their strength or mind-body connection.

Michelle Moore, ISSA Certified Personal Trainer

Fitness Philosophy: I remind my clients why they started in the first place — whether it’s the desire to build strength or have the mobility to play on the floor with grandchildren without needing help up.
