What Your
Session
Looks Like.
Every assessment runs in the same sequence, and the tests that cause no fatigue come first so that each result reflects your full capacity when you reach it.
You stand barefoot on the Seca platform while the scan runs for one minute, passing a low-level electrical signal through the body to measure how the different tissues conduct it. Height and segment lengths are recorded at the same time and give context to every force and velocity output that follows.
You move through a set of fundamental patterns: a bilateral squat, a single-leg squat on each side, a hip hinge and an overhead reach. The OpenCap cameras capture your mechanics in three dimensions as you move, and the coach reviews what gets flagged before moving to the next test.
You stand on dual force plates and perform a series of jumps, including countermovement, squat and reactive variations, with several attempts and full rest between each one.
You sprint through timing gates at 10 meters, 20 meters and 40 meters with full recovery between attempts. You also run top speed flys, where you take a rolling start and hit the gates at full velocity.
You wear a mask connected to the analyzer and cycle through progressively harder resistance stages on the Lode bike ergometer, with each stage lasting 2 to 3 minutes. The test runs to volitional failure or until the termination criteria are reached.
Body Composition & Anthropometrics
You stand barefoot on the Seca platform while the scan runs for one minute, passing a low-level electrical signal through the body to measure how the different tissues conduct it. Height and segment lengths are recorded at the same time and give context to every force and velocity output that follows.
Lean mass read against force and speed outputs predicts athletic potential better than bodyweight alone. Segmental lean mass shows whether there is a meaningful side-to-side deficit that raises injury risk.
You receive a composition report, a segmental analysis and your relative performance metrics.
What You
Walk Away With.
Athlete Profile
One document holds every test result: force output, velocity profile, sprint splits, metabolic capacity and movement quality score.
Benchmark Comparison
Your results are compared with sport and position norms, placed on percentile rankings and set against your prior Onyx test data where it exists.
Training Zones
Your VBT zones, heart rate training zones, velocity loss targets and load prescriptions are derived from your own data.
Priority Focus Areas
The report names the two or three physical qualities that will have the greatest effect on your sport performance when they improve.
The app you train with.
The app keeps six things about you, and each one reads from the others.
Train
A program chosen from your goal, experience and days, with a recommended load on every set and the reason beside it.
Recover
A morning check-in that explains its scales, and a recovery reading from your own sleep and heart rate after seven nights.
Eat
A diary that finds the product by brand, carries the vitamins and minerals, and explains any nutrient you tap.
Your sport
Practices, classes, matches, runs and walks in your week, with distance and pace, logged up to three months back.
Test
Lab results with your Onyx Score, and a home test day scored against published norms every six weeks.
Your week
A report every Monday, and a Progress tab that opens with your week and then your strength on every lift.
Continuous
Monitoring.
Onyx uses its force plates every training week, and Onyx Protocol members get continuous monitoring on top of the scheduled retests. The weekly data flags a drop in output before it becomes an injury and shows a gain weeks before a stopwatch would.
Force Plate Capture
Jump height, rate of force development and the asymmetry index are logged every training week and trended in your Onyx Performance OS portal.
Core Re-Test
Velocity profile, sprint splits and body composition are tested again and your report is updated, which comes to 9 to 11 retests a year.
Full Battery Capstone
All five tests are run again, the priority list is rebuilt from the new data and the results are compared with the same tests from the year before.
Testing Options.
Each test is booked online on an open time with a coach and paid by card when you book. The results are explained on the day and saved to your account in the Onyx Performance OS app. Prices are the same ones the lab charges at the desk.
Body composition test
A body-composition scan with a coach: body fat percentage, lean mass and the change since your last scan, saved to your account in the app.
Book body composition test →Full assessment battery
Ninety minutes across every station: force plates, sprint timing, velocity profiling, body composition and a movement screen, with a written report and a priority list for your program.
Book full assessment battery →Performance assessment
Sixty minutes on the force plates and the timing gates with a coach: jump height, peak power, left-right asymmetry, reactive strength and sprint splits, explained to you on the day and saved to your account in the app.
Book performance assessment →VO2 max test
A graded test to exhaustion with gas analysis: your VO2 max, your ventilatory thresholds and the heart-rate zones your conditioning should use, with the report in the app the same day.
Book vo2 max test →Protocol members have their retests included and book them from the app.
Assessment Is the Starting Point.
Once you have your numbers, training starts from them. Protocol and private training begin with the performance assessment, and the results build the program.
