The GSP Standard

Stop guessing.
Start measuring.

Most athletes train hard without ever knowing if it's working. At GSP, nothing is left to feel. Every athlete follows the same proven sequence — and order matters, because you can't build a plan before you've measured the athlete.

01

Assess

A complete performance assessment — speed, power, strength, and movement quality — establishes exactly where your athlete stands and what's holding them back.

02

Train

An individual development plan built from the assessment, delivered through structured small-group coaching. Every rep has a reason.

03

Track

Regular re-testing turns effort into visible numbers. You and your athlete see the improvement — measured against their own baseline.

The GSP Performance System

A system, not a workout

Every athlete moves through the same proven process — the difference is that theirs is built on their own numbers, and re-measured as they go.

01

Assess

Every athlete starts with testing to identify strengths, weaknesses, and opportunities.

02

Develop

Athletes follow structured speed, strength, and power development built for them.

03

Measure

Progress is tracked through objective performance testing, session after session.

04

Perform

Training improvements transfer into real competition — speed, power, and confidence.

What Parents & Athletes Say

Results families talk about

Parent Questions

What parents ask first

Who is this program for?
Committed athletes ages 12–18 who want to get measurably faster, stronger, and more explosive — in any sport. Whether your athlete is just starting or already competing at a high level, training is built around their individual numbers.
What ages do you train?
Athletes 12–18. Every program is scaled to the athlete's age, training experience, and assessment results.
How is this different from a normal gym?
A gym gives your athlete a room full of equipment. GSP gives them a coach, an individualized plan built from objective testing, and documented proof of improvement. Every session is coached, and every result is measured.
How do you measure progress?
Every athlete is tested at the start and re-tested throughout — speed, power, strength, and movement quality. Those numbers live in their performance profile, so progress is something you can see, not just feel.
How often should my athlete train?
Most athletes see the fastest results training two to three times per week, but we recommend a frequency after the assessment based on your athlete's goals, sport schedule, and starting point.
What happens after the evaluation?
You'll receive your athlete's performance profile and a clear recommendation for the right program. There's no obligation — the assessment is genuinely free, and the next step is yours to choose.

Know exactly where your athlete stands.

The performance assessment is free, takes one session, and comes with no obligation. Limited times available.
