About us

More than a gym. A place where training, health, and community come together.

01 · Stahlbox

Fitness & Powerlifting since 2014

Stahlbox has been a home for functional fitness and powerlifting in Linz since 2014. Founded by powerlifter Barbara Gapp, it is run today by Lisa Pühringer.

We are not about the typical, industrial training hall, but about honest, challenging training in a group that knows and supports you – for beginners and advanced athletes alike.

02 · Owner & Head Coach

Lisa Pühringer

At 21, I took over RAEDBOX in June 2026 – a big step for me. Just a few months later, STAHLBOX joined, handed to me by powerlifting legend Barbara Gapp. Today I get to bring two different training worlds together.

Sport has been part of my life since 2019. Today I am an active competitive athlete myself, focused on functional fitness and HYROX. My experience ranges from functional training and endurance sports to several years in bodybuilding.

I completed my fitness trainer certification at 15 and then gained several years of full-time experience in training and health.

As owner, I combine solid expertise and personal training experience with motivation, personality, and a good sense of humor. It matters deeply to me to preserve the powerlifting roots and the special character of STAHLBOX while also bringing in fresh impulses.

I want everyone at STAHLBOX and in training to feel comfortable – regardless of level, experience, or personal goals.

Training should challenge you, make you stronger, and help you grow – but it should also be fun and be a place you genuinely enjoy coming back to.

04 · Our philosophy

What we stand for

At Stahlbox, it is about more than a good workout. We want to create a place where training, health, and community belong together – and where everyone feels welcome and at ease.

Personal

You are not just a number here. We know our members, adapt to different training levels, and support you on your own path.

Quality

Good training means more than just hard work. Through professional coaching, thoughtful programming, and clean movement, we help you become stronger, fitter, and more capable over the long term.

For every level

Whether you are just starting out or have years of experience – everyone trains with their own background and goals. Exercises and intensity can be adapted individually.

Fun & growth

Training can challenge you and push you out of your comfort zone – but it should also be enjoyable. We want you to see progress, take on new challenges, and look forward to coming back.

05 · Community

Train together. Grow together.

Stahlbox is shaped by the people who train with us. Different goals, different levels, and different personalities – but a shared passion for movement and training.

It is not about who is strongest, fastest, or fittest. We motivate each other, celebrate progress together, and above all enjoy training.

Whether in daily workouts, our shared Bootcamp, or simply spending time together after training – community is as much a part of Stahlbox as the training itself.

Our goal is a community where everyone feels welcome and wants to be part of it.
