About Us
We are a team of Physical Therapists, Athletic Trainers, and Competitive lifters. First and foremost though, what each of us are, are Coaches and Teachers.
​
Our Mission is to change Strength Sports for the better by helping every one of our athletes get stronger, feel better, and understand training at a higher level.
We are Rebuild Stronger.

John Flagg, Owner
Strength is something I appreciate and enjoy, but the thing that gets me out of bed in the morning is simple.
​
It's YOU. Watching you lift to your highest potential, recover from injury to get back in the gym, or hit that new PR, for reps.
​
I'm an Athletic Trainer, Competitive Powerlifter in the USAPL and USPA, and a proud girl dad (Girl Power!)
Wyatt Christiansen- Coach
I am a competitive powerlifter and coach primarily in the USPA (although I have dabbled in USAPL, WRPF, and Strongman Corp).
Outside of my own “athletic” endeavors I coach in person barbell classes, coach online, and am pursuing a master's degree in kinesiology at A.T. Still University looking to one day teach and research.
Oh and I help run multiple strongman and powerlifting competitions here in Arizona with THEE Notorious Power Sloths aka my gym family.
Outside of the gym I enjoy getting in the outdoors (mainly hiking or fishing) or enjoying a good local beer on the weekend.
Kristy Fisher- Coach
​Guiding you to find enjoyment in movement and helping you increase strength, come back from an injury, improve conditioning or optimize technique in your desired sport or activity is my main goal.
Coaching to me means working TOGETHER with my athlete to work towards THEIR goals and aspirations.
I have a Physical Therapy degree and have a special interest in pelvic health (female/male), pregnancy and postpartum exercise. I hold specialized training certificates in CrossFit, Olympic Weightlifting and Powerlifting and have been a competitive athlete in all as well. I’m Canadian and a proud #boymom excited to be a positive role model and show them we can do hard things.
Garret Wilson- The Most Badass Intern Ever​
​
I am a USAPL competitive powerlifter, physical therapy student, and newly appointed coach.
I am currently pursuing my Doctor of Physical Therapy degree at Texas State University and will graduate in May 2023. Prior to becoming a coach, I served as the Rebuild Stronger Intern.
I currently assist with performance programming and love helping others become the strongest version of themselves through customized training plans. I am also passionate about guiding others through the rehabilitation process and empowering them with the skills and knowledge to manage pain and injury.
Outside of training, I enjoy spending time with my family, fiancé, friends, and cat, as well as reading, listening to podcasts, meditating, spending time outdoors, and trying new foods.
