Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a fitness device with dual resistance. Background Technology

[0002] In the fitness equipment industry, resistance adjustment performance is a core indicator for measuring the practicality of equipment, directly affecting the controllability of training intensity and user experience. Currently, most fitness equipment on the market (such as rowing machines and exercise bikes) uses a single resistance system, which is insufficient to meet the diverse needs of users with different fitness levels.

[0003] Traditional wind resistance devices generate resistance by cutting airflow with fan blades. While the resistance dynamically changes with speed, making it suitable for simulating natural motion, it suffers from poor linearity at low speeds and rapid resistance increases at high speeds, resulting in instability and significant susceptibility to environmental airflow. Magnetoresistive devices, on the other hand, generate resistance through the interaction of a magnetic field and a conductor. They offer higher adjustment precision and smoother operation, but the upper limit of resistance in a single magnetoresistive system is relatively low, failing to meet the demands of high-intensity training, and its applicability is limited, especially in professional training settings.
