Coached strength and endurance in groups of never more than 12 — with your weights, your progressions and your programming built from your own assessment, not a class average.
No commitment. A coach will call you back — usually the same day.
At proof3, most members invest between $249 and $299 per month after their first 30 days. That covers unlimited small-group training, ongoing reassessment, personalized coaching and the technology behind it.
In a class, one instructor runs the same workout for everyone and counts reps from the front. You are a body in a room. In small-group training at proof3, a coach knows your assessment results, sets your working weights, watches how you move, and adjusts mid-session.
It is not one-to-one either — we offer that, and some people need it. But most adults over 40 do not need a coach for every repetition. They need one who is paying attention, and a program built from their own numbers rather than a class average.
Never more than 12, and often fewer. Small enough that a coach can correct your setup before a lift gets heavy.
30/30 combines 30 minutes of strength with 30 of endurance. Base40 is a dedicated endurance session.
Weights and progressions come from your proof3 Assessment, not from what the group is doing.
Then you train — a full week of small-group sessions with strength and endurance coaching built around what the assessment found.
InBody body composition, computer-vision movement screening, and strength and power testing. It produces your prf score — one number you can track over time.
One-to-one with a coach who walks you through your results and the movements you will be doing, before you ever step into a group.
What you do outside the gym decides most of your result. You leave with a plan for eating, sleep and recovery that fits your actual life.

"I struggled for years to get 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."

You do not walk into a group class on day one and hope it fits. Week one is built to find out exactly where you are, so everything after it is aimed at the right thing.
That is the job. Not counting reps from the front of the room — watching the person in front of them, and changing what happens next based on what they see.
After your first 30 days, most members at proof3 invest between $249 and $299 per month for unlimited small-group training, ongoing assessments, personalized coaching and the tracking technology. The first 30 days are priced separately because they include the proof3 Assessment, a private 60-minute session and a nutrition and lifestyle strategy.
Coached strength training in a group of never more than 12 people — often fewer — where the programming is individual rather than shared. At proof3, your working weights and progressions come from your own proof3 Assessment, and a coach adjusts them during the session. It sits between a fitness class, where everyone does the same thing, and one-to-one personal training.
Your first 30 days are priced separately, because they include more: the proof3 Assessment, a private 60-minute session, and a nutrition and lifestyle strategy built for you. A coach will walk you through the numbers on your call — no surprises.
No. The assessment exists precisely so nobody has to guess where to begin. Most people who start with us have not trained seriously in years, or have never lifted with a coach watching. You start where you are.
Yes, and it becomes more important with age, not less. Adults lose muscle mass steadily from their 30s onward, and resistance training is the most direct way to slow that. The risk comes from loading a movement pattern that is not ready — which is why we screen how you move before anything gets heavy.
Sixty minutes. Our 30/30 session is 30 minutes of strength work followed by 30 minutes of endurance. Base40 is a dedicated endurance session, also 60 minutes.
We offer both. One-to-one gives you a coach for every repetition and suits people managing a specific injury or chasing a narrow goal. Small group gives you individual programming with a coach watching the room, at a lower cost, with other people training alongside you — which for most people is the reason they keep showing up.
