Coach Nyles Stuart

  1. Certified since 2007

  2. Patient/non-intimidating demeanor

  • There is no one training style that works because each sport & individual is unique. 

    • My philosophy is to quickly determine a person’s fitness strengths as well as their desired personal fitness & weight-loss goals

    • I then work to develop a personalized training program around that athlete's strengths so I can bridge the gap between his/her strengths and weaknesses. 

    • This tactic works for both group and personal training because I tailor the exercises based on the individual’s ability.

  • My training philosophy consists of 3 phases that are in constant rotation: 

    • Core

    • Strength

    • Power​​

3. Multiple specialties: Weight loss, Muscle building, Corrective exercising, Speed, Power, Core & Strength Training.
