Using camera-based movement intelligence, we evaluate:
Flexibility
Mobility
Joint stabilityIn just four minutes, we reveal key mobility or stability issues that may limit performance or raise injury risk and give you clear, actionable strategies to improve.

Wear comfortable clothing. For accurate tracking over time, it’s best to take your scans under similar conditions (same hydration level, time of day, and fasting state if applicable). You’ll remove your shoes, socks, jewelry, and any watches or wearables prior to stepping onto the machine, and we have wipes for your feet + for the machine to ensure cleanliness at all times.
About 30 minutes total. The scan itself takes 2 minutes, followed by a 20-25-minute review with a coach to interpret the results and ask any questions you’re curious about.
We recommend doing a full proof360 Assessment every 3-6 months to capture meaningful changes in strength, mobility, and performance. You do not need to do it every month, but depending on your specific goals, we’ll recommend a bit more/less to meet you where you’re at in your fitness journey.
Monthly scans are ideal for tracking short-term progress and adjusting your plan accordingly. They’re quick, we’re talking about 2-4 minutesd all-in, and they give you great insight into your changing body composition.
Yes. We’ll prompt you when it’s time for your next check-in so you can stay on track and keep improving.
