Built to handle pressure. Backed by quality.

At Extreme Performance, we believe real performance wear must be more than just a great fit or a strong look.
Our products are made to perform under pressure. During heavy lower body sessions. During intensive workouts. During training where your clothing not only has to fit well but truly deliver.

We use high-quality materials and strong finishes because we don’t believe in leggings that only look good on camera.
While many brands use terms like squatproof as marketing labels, we build our items for the real deal: deep squats, high fabric tension, and intensive performance training.

Our leggings and shorts are developed to handle extreme stretch, pressure, and movement. The fabric, fit, and construction are chosen with one goal: to provide support when you train hardest.

Our Standard

We don’t make clothing that only looks good.
We develop performance wear that has to be tough in use.

For us, that means:

  • high-quality materials with strong stretch and recovery

  • sturdy construction and precise finishing

  • fabrics designed to maintain coverage, support, and shaping

  • items that must withstand intensive training and repeated use

We don’t call something squatproof just to sell it better.
For us, squatproof means a legging designed for real strain — for movement, tension, and intense training moments when you need to trust your clothing.

Built for Heavy Training

Extreme Performance is designed for women who train seriously.
Not for a few easy poses, but for workouts where your clothing is constantly under tension.

Think of:

  • deep squats

  • lunges

  • RDLs

  • leg days with heavy load

  • intensive strength training

  • HYROX and high-intensity training

Especially during those kinds of workouts, your clothing needs to stay in place, provide support, and inspire confidence. That’s the standard we design from.

Our Guarantee

We stand behind the quality of our products. That’s why we have a clear and honest warranty policy.

That means:

  • careful quality control before shipping

  • focus on sustainable materials and finishes

  • products that must meet our performance and quality standards

If something is wrong with your item despite normal use, we always look for a suitable solution. No empty promises and no standard rejections, but a fair assessment based on quality and use.

30-Day Returns

Doesn’t fit or isn’t what you expected? No problem.
You can return your order within 30 days, as long as the item:

  • is unworn and undamaged

  • is returned in original condition

  • including labels and packaging are returned

This way you can experience our performance wear risk-free.

Responsibility in Quality

Responsibility doesn’t stop at the sale for us.
We consciously choose materials and finishes that last longer, perform better, and need less frequent replacement.

For us, quality is not a detail.
It’s responsibility.

That means:

  • less waste

  • a longer lifespan

  • better long-term performance

Fast & Reliable Delivery

For orders within the Netherlands:
Order before 12:00 = delivered next business day*

We process every order with care and speed, so you don’t have to wait unnecessarily.

*On business days excluding holidays.

Our Promise

Extreme Performance stands for quality, clarity, and trust.
We don’t make performance claims just to impress.
We build products designed to deliver on those claims.

Built for pressure.
Built for performance.
Backed by responsibility.

You’re not average.
