The EndurancePro in action:
"It felt a bit silly at first, just breathing into it. But you feel the resistance immediately, and after a few days, you notice clear improvements. I can go much longer during exercise now, and it’s really easy to train with."
"Honestly, I thought it was nonsense. I only got it because it costs 27 euros and there's a 30-day guarantee, so you can hardly go wrong with that. I've been using it for 10 days now and I don't get out of breath as quickly when climbing stairs anymore. The resistance is easy to adjust, so I can improve bit by bit."
"As an athlete, everyone knows how important endurance is. The EndurancePro has helped me stay fit and maintain my level during the off-season, when everyone else is just chilling."
What you can expect:
Day 1
The Start
Adjust resistance, inhale and exhale for 5 minutes. It feels unfamiliar at first – your respiratory muscles are working properly for the first time.
Day 3
First change
You turn the resistance up a little. When exercising, you notice that you don't get out of breath as quickly anymore.
Day 7:
Professional endurance
You’ve trained the muscles almost no one else does. More air, more endurance – you keep going when others slow down.
How it works:
Set the resistance however you like.
Start off easy so you can ease into it. As you get fitter, simply increase the intensity. That way, the training always suits you, whether you are just starting out or are already further along.
Breathe in and out
That’s all you have to do. In the process, you’re training your respiratory muscles: something that 99% of people don’t do. 5 minutes a day is enough, and you can do it anywhere, at home on the sofa or on the go.
You have more stamina
In a few days, you'll be out of breath less often and recover faster. You'll notice it exactly when others start to tire out, because that's when you can keep going.

Scientifically confirmed!
Take a look at the current state of research in 2026:
Respiratory muscle training in athletes: A systematic review and meta-analysis
Evaluation of 21 randomized controlled trials with athletes: The meta-analyses showed a significantly positive effect of respiratory muscle training on athletic performance: measured by time trials, exercise duration, and Yo-Yo tests. Strength and endurance of the respiratory muscles improved in the studies.

Effect of respiratory muscle training on endurance performance: Meta-analysis with 46 studies
The largest evaluation of healthy athletes: In endurance tests, performance improved by an average of 16% after respiratory muscle training, and by 18.5% in intermittent incremental tests. This means: Those who train their breathing last 16–18% longer on average – with the same level of training.

Here's what our customers say:
I thought at first it wouldn't make a difference...
but after a few days I notice clear improvements in my fitness. I got it because I wanted to go all out this summer & thanks to the endurance trainer, I'm going to do just that.
Anyone who wants to get fit should use this thing!
For a long time I struggled with poor fitness, and I tried a lot of things, but nothing improved my fitness as easily & quickly as this endurance trainer!
Works for smokers, too.
To anyone who wants to counteract their smoker's lungs, try this out haha. I was always the guy who was gasping for air, and this thing helped me get back into good shape.
I am satisfied
Great products! I'm completely satisfied & you can definitely notice an improvement when running. I also don't understand some of the discontent, as the quality is super. Top products for athletes!
Cool device
At first I thought this was just another one of those things that ends up in a drawer after three days. But it really only takes a few minutes, and I do it while watching TV. After two weeks, I've noticed that when I'm jogging, I don't run out of breath as quickly as I used to.
At first, I was skeptical.
I was a bit skeptical at first and didn't think it would really do much. But you can feel the resistance right from the first use. After a few days of training, I already felt like I could breathe better and hold out longer during exercise. It's super straightforward and easy to incorporate into everyday life.
Frequently Asked Questions:
Are the products safe?
+
Yes, our products are CE-tested and 100% safe! If you have breathing problems such as asthma or similar conditions, always consult a doctor first.
How does the EndurancePro work?
+
The EndurancePro helps you improve your lungs, stamina, and overall fitness by breathing against resistance. This resistance forces your respiratory muscles to work harder and become stronger over time – helping you avoid getting winded so quickly.
Should I breathe through my mouth or my nose?
+
We recommend inhaling through the nose and exhaling through the mouth. If you want a more challenging experience, you can also just use your mouth. However, it is important to exhale through the mouth to feel the resistance.
