Data-driven rehab progression
The operating
system for
performance.
Most coaches collect plenty of data. The problem is that it sits in separate places. Testing in one tool, programming in another, athlete notes in email. Nothing connects, and every handoff loses context.
Onyx Performance OS is the platform that runs Onyx Online and the Lab. It is the software we built to run our own facility, and we are now opening it to other coaches.
Athlete Management
Profiles, an onboarding pipeline, health monitoring, and each athlete's full history in one place.
Testing & Intelligence
Force plate, sprint, body composition, and strength testing with a review step. The results feed priority signals and readiness flags.
Programming
Programs, templates, phases, and load progression, built for how coaches plan and assign work.
Scheduling & Classes
Appointments, group classes, and session planning, tied to athlete records and programming.
Nutrition
Calorie and macro targets set from testing, athlete food logging, and roster-wide adherence for coaches to review.
Reporting & Benchmarking
Session summaries, long-term trends, and cohort percentiles. Your data and your reports, with no locked tiers.
Athlete Portal
A branded portal where athletes check in, log training and food, book, and see their own progress.
Online Program Delivery
The same engine behind Onyx Online. Deliver and sell programs remotely under your own brand.
Online, in-person,
and everything between.
Onyx Online, the Lab, and the facility software all run on one platform, Onyx Performance Systems. The programs you follow, the coaching you get, and the software behind them work from the same testing data and the same standards.
When everything is connected, the training gets better and there is far less admin to manage.
We built it because
we needed it.
Onyx started on the gym floor, with a strength coach, sports scientist, and gym owner training athletes in Miami. As the Lab grew, the tools did not keep up. Athlete data lived in a spreadsheet, programming lived somewhere else, and every week took more admin than it should have.
So we built the system we wanted to use, then opened it up. Onyx Online lets you train anywhere, the Lab is where you train in person, and the OS is for coaches and facilities that want to run things the same way.
