Where performance is tested, refined, and proven.
At Next Extreme, we believe performance is not a promise, but a result.
That’s why we develop, test, and refine our performance wear in the Performance Lab — the place where every detail is backed by practice, movement, and experience.
Here we show how our products are made, why they perform, and what makes the difference during training.
No marketing talk.
Only substantiated performance.
What is the Performance Lab?
The Performance Lab is the foundation of Next Extreme.
Here everything comes together that sets our performance wear apart:
-
intensive product testing
-
thoughtful fabric and fit choices
-
real-life training experiences
-
transparency in design and development
Everything we launch is tested here before it reaches the collection.
Product Testing
Where performance is tested, not promised.
Every legging, sports bra, and top goes through an extensive testing process.
From squatproof tests to wash and durability tests — only products that meet our standard are approved.

Fabric & Fit
Designed to move. Made to support.
Fabric and fit determine how an item feels during training.
In the Performance Lab, we test and refine fabrics and fits for freedom of movement, support, and comfort — so you can fully focus on your training.

Training & Performance
Tested under pressure, in real workouts.
Our performance wear is tested where it counts: during real training sessions.
Strength training, conditioning, and high-intensity workouts form the basis for our feedback and improvements.

Behind the Design
Every detail has a reason.
Design at Next Extreme is not about trends, but about function.
In this section, we show how designs come to life, why certain choices are made, and how prototypes are refined into a final product.

Our standard
The Performance Lab revolves around one clear standard:
If it doesn’t perform during testing,
does not make it into the collection.
No compromises.
No shortcuts.
Only performance wear that supports you when you give it your all.
