In their words

Watch the work

Client Transformation

One year of consistent training. Strength up, muscle gained, fat lost — the slow way that actually sticks.

Pro athletes and first-time clients get the same thing from me: a program built for what they need, and the accountability to actually finish it.

  • “Nathan’s approach is positive and based on improving functional movement. His use of TRX is fun and effective. Nathan provided me with nutritional coaching to support my training program. In six months of working with Nathan I achieved excellent results. I lost 40 pounds and went from wearing size 38 pants to now wearing size 32 pants. My strength and personal confidence also improved. Thanks to Nathan, I am in the best shape of my life and feel healthier than ever.”
    Fernando — Chandler, AZ
  • “Over the course of the six months, we lowered my blood pressure by ten points, took off two inches around my waist, .5" off my hips, increased my flexibility, balance was improved and I have dropped 19 lbs. and still losing. I am extremely grateful to Nathan for his patience, persistence and his very respectful manner in the way he deals with his client.”
    Cathy — Gilbert, AZ
  • “From our first session, Nathan gave me hope that I could reduce my daily intake of Tylenol through an exercise program he created based upon my personal needs. Amazingly, after twelve weeks I was Tylenol free. I continue on a daily basis with an exercise plan designed for me by Nathan. I still get mild back aches some days (I am sixty), but thanks to Nathan I have a medication-free plan of attack to address the discomfort. Words cannot begin to describe how much Nathan has helped me mentally as well as physically.”
    Russ — Orange County, CA
  • “I would like to say thank you for your time and dedication in helping me with my fitness goals. Your attention to detail in making each and every movement point to the targeted muscle group is second to none. The training has removed four inches from my waistline, reduced body fat and BMI. Your focus on posture, balance and muscle tone has increased my strength and stamina, giving me an all-around healthy lifestyle at age 68.”
    Chris — Orange County, CA
