Last Sunday, April 12, 2026, everything at High Power Gym was focused on the one-year anniversary. What started as an ambitious initiative by Daryl Janmaat, his brother Robin Janmaat, and entrepreneur Bob Hoek has quickly grown into a nearly fully booked training location with a loyal member base. The formula: small-scale, intensive guidance combined with data-driven training.
Data-driven training as a distinguishing factor
While many gyms focus on volume and flexibility, High Power Gym consciously chooses focus and effectiveness. The core of the concept lies in Small Group Personal Training, where athletes train in groups of up to six people.
Central to this is the use of heart rate zones. During each training session, five zones are used, each serving a specific purpose: from active recovery and fat burning to maximum effort and lactate buildup. This approach ensures that training is not only intensive but, above all, goal-oriented.
For entrepreneurs and busy professionals, this is an important advantage: time investment and results are directly proportional to each other. No 'training by feel', but steering based on measurable progress.
Personal approach with technology as a foundation
Every member starts with an extensive body analysis, which serves as the foundation for a personal training plan. Then, during each session, a heart rate monitor and corresponding app are used, making performance visible in real-time.
This combination of personal guidance and technology provides:
Continuous monitoring of progress
Immediate adjustments during training
Insights into long-term physical development
This approach aligns with a broader trend where data and personalization are becoming increasingly important – even within the fitness industry.
More than training: building a community
Equally important as the training concept is the community that has formed around High Power Gym. According to co-founder Daryl Janmaat, a large part of the success lies there:
“From the beginning, we made a flying start. The idea behind the gym, where becoming stronger and fitter together is central, resonated immediately. Members feel part of something bigger and train not only next to each other but with each other.”
This focus on connection translates into a broader offering than just training. In addition to HIIT, yoga, and boxing, the gym offers:
A run club with joint running training
HYROX-inspired workouts
Participation in external sports events
This creates an ecosystem where members remain active outside the gym and continue to motivate each other.
Smart scalable model with clear positioning
The success of High Power Gym lies not only in execution but also in strategic choices. By opting for small groups and high-quality guidance, the gym consciously positions itself at the top of the market.
This has several advantages:
Higher customer loyalty
Stronger price positioning
Better quality of guidance
Less dependence on large volumes
At the same time, it also brings challenges, such as limited capacity. The gym is now nearly full – a signal that the concept is resonating, but also that further growth requires smart expansion.
Recovery and flexibility as added value
In addition to group classes, members have access to a private gym and a special recovery room. This allows High Power Gym to respond to a second important trend: recovery and balance.
In a time when performance is central, the awareness is growing that recovery is just as important. By offering these facilities, the gym not only increases value for members but also differentiates itself from traditional gyms.
Looking ahead: growth without compromises
With a strong foundation and an engaged community, High Power Gym looks forward. The ambition lies not only in growth but especially in further refining the concept and expanding the offering.
The challenge is clear: scaling up without losing the personal approach and community feeling. That is what makes the concept distinctive – and thus valuable.
The power of data-driven training
High Power Gym shows that success in the fitness industry is not about having as many members as possible, but about the right combination of focus, guidance, and experience. By smartly utilizing technology and simultaneously investing in community, a model is created that is not only effective but also grows sustainably.
For entrepreneurs in other sectors, there is a clear lesson: those who focus on quality, measurability, and connection build a loyal customer base faster – and thus long-term success. High Power Gym is located in The Hague and is open daily. More information can be found on the website.
