The Set is a boutique gym in Amsterdam Zuid built for people who want to feel stronger, move better and optimise their health.
BLK BOX partnered with The Set to design a refined training space that prioritises attention, quality and care. The gym operates on a clear philosophy: train with purpose, consistency and intention in an environment built to co-create with your life, not compete with it.
The Space
The Set wanted to create something different: a boutique gym built for longevity rather than intensity, where training supports life. The vision was to move away from high-volume, trend-driven fitness and build a space focused on sustainable performance, genuine connection and long-term health.
The space was designed for personal training and small group PT, requiring equipment versatile enough to support varied programming and maintaining a calm, focused atmosphere.
The Build
The Set needed a carefully curated equipment package that reflected its commitment to quality and long-term health. Every piece was selected to support sustainable performance and efficient training in a refined environment.
The space is kitted out with custom-branded 3 Series Nexus Compact Racks with integrated storage, providing a functional anchor for the gym while reinforcing The Set’s brand identity. The custom branding creates a cohesive, professional aesthetic that members recognise immediately.
Key Equipment
The Set is fitted with BLK BOX equipment selected to support varied training styles while maintaining a streamlined, intentional setup:
• Rack Attachments & Cable Attachments
• Utility Barbells (15kg & 20kg)
• 2 Tier Hex Dumbbell Rack with Hex Dumbbells
• Leg Extension/ Leg Curl Machine
The selection supports strength development, mobility work and conditioning while keeping the space organised and efficient. Integrated storage in the Nexus Compact Rack and floor-mounted bar holders maintain the clean, uncluttered aesthetic central to The Sets environment.
The Result
The finished space reflects everything The Set set out to achieve. Calm, considered and highly functional, it offers a premium training environment where members feel supported rather than overwhelmed.
The custom 3 Series Nexus Compact Rack anchors the floor both visually and practically, allowing coaches to deliver structured personal training and small group sessions with flow and precision. Integrated storage and a tightly curated equipment selection keep the space clear, reinforcing the gym’s minimal aesthetic and focused atmosphere.
More importantly, the layout enables purposeful programming. Coaches can move seamlessly between strength work, accessory movements and mobility without disruption
Jayne Lo, BLK BOX Business Development Manager, who played a key role in delivering the facility said:
“This project was about flow and focus. The layout supports how sessions are actually delivered, while the equipment selection keeps the space purposeful. Every detail has a job, which allows coaches to programme effectively and members to train with real intent.”
