Welcome to Gymextensions

We are Refined Design, dedicated to developing innovative, high-quality fitness products designed to enhance your workout experience.

Our Product Line

Our first design originated from our own experience with strength training. While working out, we noticed that dumbbell exercises improve the Range of Motion, but controlling the movement is often difficult. This challenge became the starting point for a solution that makes training more effective, more enjoyable, and more fun.

Sustainability and Transparency

Sustainability is an integral part of our process. We work with recycled plastic, opt for eco-friendly packaging, and take you through every step of the design process. Every choice in the design and production can be justified, so you know exactly what you’re using and why.
