Your wellness journey begins with a single number.

Using the data from your proof360 assessment, our proprietary algorithm calculates your prf score™ (Performance Readiness Factor), a single, trackable number that serves as your personalized longevity baseline.

Once your prf score is established, our AI-powered system builds a tailored program aligned to your fitness and wellness goals, lifestyle, and performance level.

You’ll review your plan one-on-one with a dedicated coach, so you’re never navigating your health alone.

I feel amazing about my progress at proof3. I work and have two children, so my time matters a lot to me, and knowing my coaches and program are outstanding is important. And, I LOVE training with the people at proof3. It's become a joy to be there!

Janice

proof3 is a great environment to workout and get healthier! I struggled for years to getting to the gym regularly, but proof3 has me motivated to return as many times a week as I can. In just a few months, I'm feeling better than I ever have, and I'm 50!

Brett

I wasn't even looking for a new gym, but when I tried proof3's assessment and then their classes, I fell in love right away. I have a 9 month old baby girl, and knowing that I am building strength and longevity brings me a lot of peace. You'll love it there!

Maggie

I've done plenty of fitness before, from CrossFit to training with a program on my own, but when I walked into proof3 I knew instantly that it was different. The coaches are fantastic, the classes are challenging but fun, and the technology is super cool!

Elena

I am a practicing chiropractor, and many fitness gyms ask me to try their gyms out, but I was blown away by proof3's assessment and coaching philosophy. I will be recommending proof3 to my patients for sure

Learn More

How should I prepare for my proof360 assessment?

Wear comfortable clothes and athletic shoes that you can move in. No sweat, no warm-up. Just show up and we’ll take care of the rest.

How long will I need to take the proof360 assessment?

Sixty (60) minutes total. The assessment itself takes about 30 minutes to complete. Then, reviewing the results with an experienced coach typically takes another 30 minutes because we want to make sure you understand what you can do to achieve your health and longevity goals, not just leave with another useless number in hand.

How often should I do a proof360 assessment?

We recommend you get a full proof360 assessment 2 x/yr. because strength gains can take a while to achieve. The InBody body composition scan (one of the four pillars of the proo360 assessment) can be done more frequently if wanted (e.g., monthly).

Does proof3 offer any other assessments?

In addition to offering the full proof360 assessment, and InBody Body Scan + Coach assessment is available.
