Description

A rowing machine that allows for easy adjustment of training intensity Technical Field

[0001] This utility model relates to the field of rowing machine technology, and in particular to a rowing machine with an electric tensioner. Background Technology

[0002] A rowing machine is an indoor fitness device that effectively exercises the muscles of the legs, waist, upper limbs, chest, and back. Existing rowing machines can be broadly categorized into hydraulic, air resistance, magnetic resistance, and water resistance types based on their power source. However, these types of rowing machines are either bulky, complex in structure, and require a large area, making them unsuitable for home or indoor use; or they have a fixed resistance level that cannot be adjusted to suit different users.

[0003] Chinese invention patent application No. 2021110853373 discloses a novel rowing machine, comprising a main frame, a front support base, a rear support base, a slide, a pedal, a hand lever, a display, and a rowing box body. The front part of the main frame is fixedly connected to the front support base, and the rear part of the main frame is fixedly connected to the rear support base. The slide is located above the main frame and slides along the direction of the main frame. A pedal is provided at the rear of the main frame and is fixedly connected to the main frame. The rear end of the main frame is fixedly connected to the rowing box body through a bent pipe. The rowing box body is fixedly connected to the rear support base. The rowing box body is a sealed, hollow, vertical structure, and its interior is filled with liquid. A display is provided at the upper end of the rowing box body.

[0004] In the above technical solution, although the rowing box body with a vertical structure extends upwards, reducing the footprint of the equipment, the rowing machine uses water resistance as its power source, making it difficult to accurately adjust the resistance and achieve precise control. Therefore, the training force cannot be arbitrarily adjusted, which fails to meet the needs of various users.

[0005] Furthermore, existing rowing machines still occupy a large area and are inconvenient to store when not in use.
