The seat cushion configured by the prior exercise bicycle is of a fixed angle and is close to a horizontal angle, and when people of different statures use different riding postures for training, the front end of the seat cushion can press the crotch of a rider, so that discomfort and damage are caused, and the comfort is poor.

Referring to fig. 1-5, one embodiment of the present disclosure provides an Exercise apparatus, which may be a sitting rowing Machine (Seated Row Machine), a sitting back stretcher (Seated Back Extension Machine), a Leg lift Machine (Leg Press Machine), a sitting chest pushing Machine (Seated Chest Press Machine), a sitting shoulder pushing Machine (Seated Shoulder Press Machine), a sitting abdominal training Machine (Seated Abdominal Crunch Machine), a Leg bending Machine (Leg bending Machine), a Leg bending Machine (Leg Extension Machine), an Exercise Bike (Exercise Bike), and the like. In this embodiment, an exercise apparatus will be described as an exercise bicycle.

The exercise machine comprises a seat cushion 10, an adjusting member 20, a machine body 30 and a connecting rod 40. The seat cushion 10 is hinged to the body 30, one end of the connecting rod 40 is slidably connected to one of the seat cushion 10 and the body 30, the other end is hinged to the other of the seat cushion 10 and the body 30, and the adjusting member 20 is used for pushing the connecting rod 40 to drive the seat cushion 10 to rotate, wherein the connecting rod 40 is slidably connected to the seat cushion 10 and hinged to the body 30 as shown in fig. 1 to 3, and the connecting rod 40 is hinged to the seat cushion 10 and slidably connected to the body 30 as shown in fig. 4 and 5. Because the adjusting piece 20 can push the connecting rod 40, the connecting rod 40 drives the seat cushion 10 to rotate, thereby realizing the function of adjusting the angle of the seat cushion 10, being suitable for different crowds or training by using different riding postures, and having better comfort. In addition, the seat cushion 10, the machine body 30 and the connecting rod 40 can form a triangle structure, the hinge point of the seat cushion 10 and the machine body 30 forms a first vertex of the triangle structure, the connecting rod 40 is connected with the seat cushion 10 or the machine body 30 in a sliding manner to form a second vertex of the triangle structure, the connecting rod 40 is hinged with the seat cushion 10 or the machine body 30 to form a third vertex of the triangle structure, and the triangle structure has good stability.

In some embodiments, the adjuster 20 is threaded into one of the seat cushion 10 and the body 30 that is slidably connected to the link 40 and abuts the link 40. The adjusting member 20 may be screwed in close to the connecting rod 40 or unscrewed away from the connecting rod, where when the seat cushion 10 needs to rotate upwards, the adjusting member 20 is screwed in to push the connecting rod 40, the included angle between the connecting rod 40 and the vertical direction is reduced, and the connecting rod 40 drives the seat cushion 10 to rotate upwards, as shown in fig. 2; when the seat cushion 10 needs to rotate downwards, the adjusting piece 20 rotates out, the seat cushion 10 rotates downwards under the dead weight or under the pressure to push the connecting rod 40, and the included angle between the connecting rod 40 and the vertical direction is increased, so that the connecting rod 40 keeps abutting with the adjusting piece 20.
