Three
principles
and one standard.
Onyx is built on objective data, and every decision about your training runs through it.
Testing First
Every athlete begins with a comprehensive assessment battery that covers force plate, velocity, sprint and metabolic testing. The data defines the starting point.
Precise Programming
The results shape the plan. Every training variable, including load, volume, intensity, and frequency, is derived from your test data and the demands of your sport.
Measured Progress
Progress is measured on the plates and the gates. Retest cycles every 4 to 6 weeks show whether your numbers are moving, and your program adapts when they don't.
Built in
Miami
for
Athletes.
Onyx Performance Lab was founded to give athletes in Miami access to the same level of sports science infrastructure available to professional franchises. The lab operates from Allapattah, minutes from Wynwood, Midtown, and Downtown Miami.
We built the facility around data collection and performance testing. Every tool, protocol, and program in the building exists to move your numbers.
The Expertise
Behind the Lab.
Strength & Conditioning
The coaching staff holds the CSCS from the NSCA and writes periodized, sport-specific programs for team and individual sports.
Sports Science
We run force-velocity profiling, rate of force development analysis, and bilateral asymmetry assessment, and each finding leads to a training intervention.
Speed & Power
A certified sprint coach leads ground reaction force analysis, acceleration mechanics, and maximum velocity development.
Youth Development
Youth programming follows the Long-Term Athletic Development (LTAD) model, with age-appropriate training for athletes 10–18.
Metabolic Conditioning
We test VO2 and lactate threshold, profile the energy systems, and prescribe conditioning from the results.
Technology & Analytics
The staff works at an expert level with force plate systems, VBT devices, and performance reporting software.
Active
Research
Site.
Onyx Performance Lab operates as an active research facility in partnership with two of South Florida's leading universities. The equipment, protocols, and data environment here are the same ones used in peer-reviewed sports science research.
University of Miami
Dissertation research in sports science and biomechanics is conducted at this facility. The Hawkin Dynamics force plate system, OpenCap 3D motion capture, and metabolic testing equipment are used in active doctoral-level research, and these are the same assessments used with every Onyx athlete.
Florida International University
FIU's sports science graduate and undergraduate programs use Onyx as an off-campus research site. Faculty and students have access to the full equipment battery for study design, data collection, and applied research in human performance.
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.
Alejandro Garcia
Alejandro is the founder, a strength coach and a sports scientist. Onyx Performance Lab is built from his background in both applied coaching and academic research at the University of Miami and Florida International University.
See the Lab
In Person.
You walk through the space and see the force plates, the VBT rigs, the sprint lanes and the testing bay. You meet the coach, ask your questions and see how a session runs before you decide. Pick an open time and come by.
Three Ways
to Start
at Onyx.
Adults start with a free class, youth athletes with a free evaluation, and competitive athletes with a performance assessment. All three are booked online.
