WHO WE WORK WITH
Teams & Clubs
We collaborate closely with coaches & support staff to integrate performance diagnostics into your wider strategy — from pre-season baselines to in-season monitoring and return-to-play protocols.
For formally structured teams, we ensure your staff fully understand our reporting, with clear guidance on how to interpret athlete progress and adapt programming accordingly.
For smaller clubs or teams without a dedicated support staff, we work directly with your coaches and athletes in a collaborative way — providing education, context, and ongoing support so everyone gets the most from the data.
What Your Squad Can Assess:
- Group pricing & custom packages
- Off-season to in-season monitoring
- Dedicated Testing Days
- Coach friendly reports
Individuals
We work with athletes across all levels — from first-time endurance racers to national qualifiers and weekend warriors. Whether you’re supported by a coach or managing your own training, our testing provides objective insight you can trust.
You will receive more than just a test result. Our experienced team will:
- Explain your results in plain English
- Highlight key metrics that matter
- Provide actionable recommendations
