Accordingly, a user is allowed to sit on the seat of the riding type elliptical machine in a comfortable posture; meanwhile, the user can acquire sufficient exercise in cooperation with the elliptical movement of the pedal device.

Description

Seated elliptical machine

The invention relates to fitness equipment, and in particular to a sitting elliptical machine.

Due to factors such as working hours or the home environment, many modern people have begun to choose indoor fitness equipment as a way to exercise, in order to maintain the body's basic fitness, and among the many indoor fitness equipment, among them are elliptical machines and stationary bicycles. The physiological load caused by the user can best meet the needs of users, and thus become the two most popular fitness equipments.

Firstly, in the case of an elliptical machine, it is mainly for the user to repeatedly step on the left and right pedals to move along an approximately elliptical trajectory to achieve the purpose of simulating leg movements such as walking, running or climbing, but during operation. In this case, the user must maintain standing for a long time, so that it is easy to impose a certain burden on the user's lower limb joints or muscle groups. In addition, in the case of a stationary bicycle, the flywheel is continuously rotated by repeatedly stepping on the left and right pedals, although the burden on the lower limb joints or muscle groups is less than that of the elliptical machine, but in a circular path. The amount of exercise that can be achieved by the way of pedaling is quite limited. Therefore, how to combine the advantages of the traditional elliptical machine and the stationary bicycle to develop new fitness equipment has become an urgent problem to be solved in the industry.
