The EndurancePro in action:
"A teammate from the youth academy recommended it to me. I looked at him like he was crazy at first, but after trying it out for a few days, I already noticed noticeable differences in my fitness."
"Great products! I’m completely satisfied & you can definitely notice an improvement when running. I also don’t understand some of the dissatisfaction, as the quality is super. Top products for athletes!"
"As an athlete, everyone knows how important endurance is. The EndurancePro has helped me, especially in the off-season when everyone is chilling, to stay fit and not lose my edge."
How it works:
Set the resistance however you like.
Start off easy so you can get into it. As you get fitter, you can simply increase the intensity. That way, the training always suits you, whether you’re just starting out or are already more advanced.
Breathe in and out
You don't need to do anything more. By doing this, you train your respiratory muscles: something that 99% of all people don't do. 5 minutes a day is enough, and you can do it anywhere, at home on the sofa or while on the go.
You have more stamina
In a few days, you will be out of breath less often and recover more quickly. You will notice it exactly when others are already flagging, because you can keep going.

What you can expect:
Day 1
The Start
Adjust the resistance, inhale and exhale for 5 minutes. It feels unusual 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 that almost no one else does. More air, more stamina – you keep going when others slow down.
I thought at first it wouldn't make a difference...
but after a few days I'm noticing clear improvements in my fitness. I got it because I wanted to go all out this summer & thanks to the endurance trainer, that's exactly what I'm going to do.
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 looking 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.
For the price, you can't complain.
Honestly, I thought it was nonsense. I only got it because it costs 25 euros and there’s a 30-day guarantee – 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.
Cool device
At first, I thought this was just another thing that would end 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 go jogging, I don't run out of breath as quickly as I used to.
At first, I felt stupid.
Honestly felt a bit silly breathing into it at first. But you feel the resistance immediately, and after a few days I didn't want to go without it anymore. I can go much longer during workouts now.
Scientifically confirmed!
Take a look at the current state of research in 2026:
Effects of respiratory muscle training in para-athletes: A systematic review and meta-analysis
This overview suggests that respiratory muscle training (RMT) can improve the strength and endurance of the respiratory muscles.

Effect of inspiratory muscle training on performance in trained middle-distance runners
The present study conducted a 4-week respiratory muscle training program to investigate its effects on the athletic performance of recreational runners. Our results showed that the 4-week inspiratory muscle training (twice daily, 5 days a week) significantly improves inspiratory muscle strength, increases 800-meter running performance, and reduces the rate of change in leg blood flow. A possible mechanism is that the increase in maximal inspiratory pressure (MIP) can delay respiratory muscle fatigue, ultimately improving 800-meter performance.

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, endurance, and general fitness by breathing against resistance. The resistance forces your respiratory muscles to work harder and become stronger over time—so you don't get out of breath as 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.
