I was originally looking for a “master” type strength program. Proof 3 has changed my thoughts about growing older. I’m now lifting heavier weights on the lift side and greater endurance on the breathe side. I feel and look better than ever. Grateful for the smaller size classes and professional coaches.

The one on one coaching and mix between weight lifting and cardio was 10\10. Highly recommend anyone looking for a group setting training environment but feels like one on one training. The coach was amazing too!

I loved my first workout at proof3 Salt River! The class ran smoothly, everything was explained really thoroughly, I enjoyed the lifts and felt like I got an extremely good workout in! Loved having the InBody and strength assessment done too, it gave me so much insight into my body and how I can upgrade it and be healthier and stronger. My favorite thing about this gym is the minimal, modern design. Every detail was thought of in order to keep things simple, clean and aesthetic! I am obsessed!!! Also having the iPads and technology side of things allows people to keep track of their numbers so easily and be more aware of the progress being made, which is very motivating! All around loved it!!

There’s no other gym experience like this! I lift 6 days a week. Typical body building splits. I normally would not do any type of class, but I really enjoyed this class at proof3 and got a good pump in. The testing they did to help me improve on my strength and movements was next level. 10/10 would recommend!!!

I’ve had a tough time managing my workload relating to working out, so I’m either super sore or hurt (in some way), came to proof3 to see if I could maintain or build and not be sore/hurt..it’s been the best experience! I feel great, my joints feel so much more mobile/ROM, and I’ve definitely gotten stronger. My cardio has improved a ton (wasn’t doing much of that before!). You just gotta come in and try it.

this place is literally THE BEST!!!! The workouts feel very personalized and the data-driven approach is a huge motivator, helping realize goals and preventing burnout and plateau. Carl and Jon are super knowledgeable and supportive so no matter where you are in your fitness journey they will meet you where you’re at and get you going where you want to be! I came in with almost no experience strength training and i couldn’t even do a simple lunge but my first InBody assessment was a huge wake up call to how much I need to work on. I went from zero experience working out to coming in 3-4x/week and it’s honestly the best part of my day.

Every day I come out of class feeling so accomplished and so energized and it’s actually had a ripple effect on the rest of my life, too! I’ve made awesome strides in the gym but also my sleep and appetite have improved, my daily routine has stabilized, and my mental health has skyrocketed! I’m more productive at home and work after a morning at proof3.

The space is really clean, well organized, and very aesthetically pleasing with a variety of weight options.

Signing up for proof3 is the best thing I’ve ever done for myself and it’s 100% worth every penny!

Proof 3 is exactly what the fitness market needed, health and wellness approach to workouts, knowledgeable coaches, in depth tracking of your results. Competed in CrossFit for years at a high level and I’m so excited to have found a programming pushes you but doesn’t leave you in aches and pains the next day, and coches that are incredible.
I’m so happy to have found them! The best in the business

I was recently diagnosed with moderate hip arthritis at 38. I struggled to adjust to my body's new norm and I was skeptical about what training could improve.

With the help of the Proof3 team, my hip is feeling more stable and pain-free than it has in months. As a result of their mix of functional strength training and conditioning, paired with regular tech driven metrics tracking, I'm more confident than ever that I can live a full and active life.

Proof4 is a great place to take trackable steps towards my fitness goals. One being a physical fitness assessment using new technology they are using. Another is their focus on longevity as a main part of the fitness goals. I already notice I am stronger in general. The staff is very professional with lots of information. I would highly recommend Proof3 to anyone that is serious about improving their health and fitness.

I had an amazing experience! The facility was exceptionally clean, and the communication was top-notch. The trainers were not only inspiring and motivating but also incredibly detailed in their approach. The technology used is fantastic—I love going home with real stats that give me a true picture of my progress, beyond just what I see in the mirror. The atmosphere is professional yet fun, making it a place I genuinely enjoy coming back to!

Great environment to workout and get healthy! Struggled for years getting to a gym regularly but Proof3 has me motivated to return as many times a week as I can. In just a few months feeling better than I ever have at 50

Super impressed with what the team at Proof3 is doing. They have created an environment where I feel supported, encouraged, and yet still pushed to be better - but without the yelling or "big dawg" energy! (That's a good thing in my opinion!) The data driven approach to functional fitness has been outstanding at helping me compete with myself - I find myself wanting to ensure I continue to improve my numbers, which also means I am continuing to get stronger in the ways that matter to me (eg. I am currently 42 and want to continue to have as much of this mobility at 82). There was zero judgment as Karl walked me through the results, just facts and suggestions of how to improve. Highly recommend the gym and am grateful to have found a new and sustainable fitness approach!!!
