The invention discloses a pedal. The pedal is characterized in that the pedal is a body-building pedal which can be hung under a table top and can be used for realizing leg exercising in a sitting way; the connecting center of the pedal is an inserting buckle, through holes are formed in the two ends of a female buckle at the upper end of the inserting buckle, one end of each of two fixing ropes is connected with each through hole, and the other end of each of two fixing ropes is connected with a hook; when the pedal is installed, the hooks are hung at the two sides of the table top, the fixing ropes are properly adjusted according to the width of the table top, a male buckle at the lower end of the inserting buckle is connected with a connecting belt, the lower end of the connecting belt is connected with an U-shaped connecting rod through a connecting ring, and the two pedal bodies are arranged on the U-shaped connecting rod; when the pedal is used, the length of the connecting belt is firstly adjusted by the male buckle, each pedal body is in the proper height, then two feet are put on the pedal bodies, the balance is maintained by the leg force on the hung pedal bodies, and the larger action can be actively performed, so that the balance feeling can be exercised, and the blood circulation is promoted to exercise leg muscles. The pedal has the beneficial effects that the design is simple, the reliability and durability are realized, and the practicality is higher.
