With Mike from Fit With Fire, everything revolves around getting stronger within a loyal, close knit community. Functional strength training helps you become stronger, more mobile, and overall fitter, so everyday life feels easier and more sustainable. Training takes place outdoors at the Gele Pomp in Amsterdam Noord. Using kettlebells, dumbbells, bars, plates, and even a pull up bar, he continues to expand his open air gym step by step. This is pure outdoor training, year round, no matter the weather, because it builds resilience.
How Mike got started
Michael “Mike Fire” Vervuurt was once a DJ and photographer. Always surrounded by people, always entertaining, but longing for a healthier lifestyle. In 2015, he retrained as a fitness coach. In 2020, the pandemic caused his regular work to disappear, but fortunately he was still able to offer outdoor training sessions. More and more groups started to form, with all communication running through WhatsApp. Practical for a while, but not sustainable for a solid long term future.
Mike realized, “This could really become something, and if I want to take it seriously, I need a website and a proper booking system.” After researching other fitness businesses and comparing quotes and software demos, Trainin clearly came out on top.
Trainin gives Mike from Fit With Fire peace of mind
Since Mike started working with Trainin, his focus is exactly where it should be: delivering high quality, varied, energetic, and above all enjoyable training sessions.
“It gives me peace of mind. The only thing I need to think about is the class I’m about to teach; everything else runs smoothly,” he says.
Even older clients who sometimes need a bit of extra guidance find the system easy to use. That creates calm and confidence, both for Mike as a trainer and for his participants. Besides the fact that clients love training with him, Mike is also a valuable partner to us: reliable, enthusiastic, and truly client focused. The way he supports his members perfectly reflects the level of service and personal attention we stand for as well.
Growth that feels like fire
Mike would recommend Trainin without hesitation:
“The product is solid, works reliably, is available in Dutch, and when I reach out, I get an immediate response. It simply takes the pressure off.”
And that peace of mind pays off.
The results speak for themselves:
More than 150 active products
His highest revenue ever
60 percent growth compared to last year
A steady stream of new participants
“Without Trainin, this growth would not have been possible,” he continues. “I’m moving from one victory to the next.”
Trainin in three words according to Mike
Always reliable
With Fit With Fire, Mike proves that organic growth through patience and perseverance does not have to be complicated at all. By automating what needs to be automated, space is created for what truly matters: being outdoors, making people stronger, and building a community that comes together every week with motivation and energy.
We are incredibly proud and truly enjoy supporting the entrepreneur, but above all Mike as a person, with a tool like Trainin. We look forward to the future and to continuing our collaboration with Mike.
