Sporting Goods, Fitness and Recreation Equipment Design MyEquilibria Outdoor Gym by Metalco Active Created by Metalco Active, the beautiful design of MyEquilibria outdoor gyms blend into outdoor environments. A 7m tall ‘Fitness Tree’, is a concept that brings together art, design, new materials, workout equipment and community. With different configurations, these 'Wellness Parks' allow for up to 30 users simultaneously. Metalco Active produces the equipment using moulded and hand-polished, multi-patented 'Ultra High Performance Concrete' which is more efficient than traditional concrete. UHPC seamlessly integrates with high-grade Inox Steel for an enduring outdoor gym.
