[0002] Fitness chair is a widely used fitness auxiliary equipment with various forms. Its main function is to provide a support platform for users. Fitness chair can be used alone for various fitness training, such as sit-ups, goat extensions, flat butterfly abdominal contraction, etc.; it can also be used with free equipment such as dumbbells and barbells to perform various fitness training, such as: barbell bench press, dumbbell fly, hip thrust, etc.; it can also be used with fixed equipment such as Smith machine and fly rack to perform various fitness training.

[0003] The existing patent (Announcement No.: CN202892794U) discloses a multifunctional fitness chair, which consists of a chair frame, a chair board, a backrest, a spring rotating column and a foot lever. The chair board is fixedly connected to the chair frame through a fixing plate. When a person sits on the chair board and leans on the backrest, the backrest drives the spring rotating column to move downward, and the backrest is parallel to the plane of the chair board. When standing up, the human body forms a rebound force with the help of the spring rotating column and the human feet exert upward force on the foot lever, so as to achieve the effect of easy exercise and fitness. However, this technical solution still has shortcomings, as follows:
