Rock Solid Fitness: The new trusted name in high quality and uniquely designed fitness equipment.
Our journey began with the realization that the available options for adjustable dumbbells were not meeting our expectations. We found a lack of high-quality adjustable dumbbells that were designed the way we liked.
We didn’t like the big square and bulky adjustable dumbbells, and we didn’t like the dumbbells with an awkward “skeleton” no matter what weight we chose.
The result was our amazing TectonicPlates, which feature a sleek and minimalist design while still providing the functionality and adjustability you need to take your workouts to the next level.
