Summary: BOLDR replaces heavy iron weights and uneven resistance bands with a specialized electromagnetic motor. Get 3–30 kg of constant digital resistance in a format that fits in your hand – optimized for professional cable training at home.
THE TECHNOLOGY BEHIND 30 KG OF DIGITAL WEIGHT
How can a device that weighs so little generate 30 kg of resistance? The answer is electromagnetic force. Inside every BOLDR is a motor that creates digital resistance, similar to the technology found in stationary gym machines like Tonal, but in a portable format. This provides you with a completely linear load – meaning the weight feels exactly as heavy throughout the entire movement, unlike resistance bands which only get heavy at the end.
We chose this technology because it enables precision. You set your weight with 1 kg accuracy directly on the device or via the app. As former swimmers and football players, we’ve always preferred cable training for its versatility and natural paths of motion. With BOLDR, we’ve brought that luxury gym feel into the home. Read more about the technology and battery life in our FAQ.
SMARTER THAN DUMBBELLS, BETTER THAN BANDS
Dumbbells are limited by gravity and take up an enormous amount of space if you want to cover the 3–30 kg range. BOLDR gives you the same resistance but lets you train at angles that dumbbells can never reach. Additionally, you can track your total volume and speed in every rep – data that dumbbells simply can’t provide.
We’re tired of "fitness gadgets" that don’t deliver. BOLDR is a serious tool for serious training. We offer a 2-year warranty and have our support based in Malmö, so you can feel secure with your investment in the future of fitness. Want to see what the exercises look like?
