The best treadmills for gyms are commercial treadmills built for continuous, high-traffic use. These machines feature heavy-duty frames, high user weight limits and full commercial warranties, ensuring long-term reliability on busy gym floors. Many gyms choose a mix of motorised treadmills for general fitness and performance training, alongside self-powered, often smaller footprint treadmills such as curved models, where it is the user’s movement that creates the resistance and intensity. With Physical, all models are commercial-grade.
