Wii training

Dumbbells with Adjustable Loads

Make training easier,
Improve performance

Rethinking user experience and product design together

With the development of new practices such as crossfit or bodycombat and the rise of franchises for the general public, sports halls are flourishing all over France.

The market for sports equipment dedicated to bodybuilding is growing rapidly. Technologies and new materials combine to create the best possible experience for users.


WII TRAINING sells weights and fitness equipment and appliances. Aiming to improve its customers’ training conditions and performance, WIIT also designs and develops its own equipment. 

Loading and unloading weights was complicated when several people used a bench at the same time. Consequently, WIIT were looking for a solution to change weights easily, without the independent, and easily misplaced, locking system.



The agency began by studying fixing solutions that were directly integrated into the weights. Several possibilities were found. 3D printing models were made to validate the most relevant of the different concepts. 

Once the solution was decided on, we started work on the product design of the dumbbells. Finding a visual identity is crucial in the ultra-competitive sports equipment market. However, we never do this at the expense of the product’s overall ergonomics. Consequently, we opted for a sober, robust design that makes it easier to handle the weights. 


We carried out the modelling and functional prototyping of a pair of dumbbells and their 28 weights in our workshop.

Despite a tight schedule, the agency was able to deliver the first prototypes in time for a first public presentation at the Body Fitness 2019 show in Paris.
