The revolutionary combination of targeted stretching and simultaneous strength loading stimulates the muscles to learn new movement patterns and regain their natural length.

Reboots Recovery

This innovative application improves your recovery.

Reboots Recovery

During training, your muscle is damaged and metabolic waste products accumulate there. During the regeneration phase, your body removes these substances bit by bit.

By massaging with reboots, you can accelerate the removal and thus your regeneration. The results:

The effect of reboots has been scientifically confirmed:

The latest study with Innowearable was able to scientifically prove that the use of reboots significantly improves neuromuscular recovery after intensive training sessions.

Due to the crucial role that the neuromuscular system plays in the coordination and resilience of our muscles, it can be concluded that a 45-minute compression massage causes athletes to return to a training-ready state more quickly.

In the Muselgym, the reboots are available to every member free of charge.

SUP Boards

Our own SUP boards are at your disposal at all times.

SUP Boards

The trainer

My name is David Steffes. I was born an athlete in 1984: my parents were successful runners, so I was partly born with the talent.

I gained my first experience in the swimming club at an early age and started my soccer career at the age of 9. In between, I gained my first experience as a triathlete before focusing completely on running at the age of 15.

During my school year abroad in Colorado/USA in 2001, I came into contact with strength training in a gym for the first time and have been a hybrid athlete ever since.

I understood the importance of strength AND endurance training paired with flexibility training and it has been with me since that day.

In the meantime, I devoted myself to football again, but my running shoes were always at hand and I trained constantly in a gym.

I am now an ambitious Hyrox athlete and performance coach. In 2018 I finally set up my own business as a personal fitness trainer and nutritionist with the focus on training people where they need me.

My rolling gym was the first mobile fitness studio in Europe. Seven years later, I am now proudly opening my first gym at a permanent location. And there are more to come. The Muselgym is the first result of my many years of experience.

Testimonials

Together we will also achieve your personal training goal

„Der mobile Personal – und Fitnesstrainer David Steffes hat mir durch seine gezielten und effektiven Übungen eine nicht geglaubte Fitness für mein recht hohes Alter gegeben.

Seine Übungen sind gezielt, abwechslungsreich, unkompliziert und trotzdem konstruktiv. Ich habe eine viel größere Beweglichkeit gewonnen und dabei noch Gewicht verloren. Dazu kommt, das meine Ausdauer sich stark verbessert hat.

Es macht ungeheuren Spaß, ihn bei seinen lockeren und spaßigen Korrekturen zu erleben.“

Erwin Esly (82)

„I have been training with David “à domicile” since 2019. The routine has always been adapted to my level of fitness and varied from time to time.

I have found the training very helpful in encouraging me to maintain a reasonable level of fitness for my age (70 years). David has always been flexible in facilitating my travel schedule. An excellent professional!“

Michael (71)

“Dank Davids Coaching hab ich gelernt, meinen Fähigkeiten zu vertrauen und bis an meine Grenzen zu gehen (da, wo sie wirklich sind) und sie auch noch weiter hinausgeschoben. Wodurch eine ganze Menge an persönlichen Bestleistungen zustande gekommen sind.”

Sigrid

„David hat mich über mehrere Wochen gecoacht und ich kann ihn nur als außergewöhnlichen Fitnesscoach weiterempfehlen. Ich bin 14 Jahre alt und spiele Fussball. Ich hatte das Vergnügen über 5 Wochen mit ihm Outdoor zu trainieren und kann mit Überzeugung sagen, dass David durchweg beeindruckende Ergebnisse erzielt hat. Besonders in den Bereichen der Schnellkraft, der Koordination, der Explosivität und der Technik habe ich mich in diesem Zeitraum merklich verbessert.

David hat die Fähigkeit, individuelle Bedürfnisse und Ziele zu erkennen und darauf abgestimmte Trainingspläne zu erstellen.

Ein besonderes Merkmal ist seine positive und motivierende Art. David schafft es, die Trainingssessions abwechslungsreich, herausfordernd und gleichzeitig äußerst angenehm zu gestalten.

Zusammenfassend kann ich David uneingeschränkt empfehlen. Er ist ein außergewöhnlicher Fitnesscoach, der durch Fachwissen, Motivation und einfühlsames Coaching hervorsticht. Ich bin David sehr dankbar da seine Trainingssessions meine athletischen Fähigkeiten, meine Motivation und mein Selbstwertgefühl gesteigert haben.“

”Being a great athlete himself, David is an exceptional trainer who has deep sports knowledge. Whether you’re a beginner or a seasoned athlete, he’ll motivate you to reach your fitness goals.
