In the embodiment of the invention, the base is used for supporting the whole intelligent waist twisting training device with the air resistance source, the base can be provided with a plurality of support legs, one sides of the support legs facing the ground are fixedly provided with the rubber pads, the rubber pads can prevent the support legs from being in direct contact with the ground, and the rubber pads can also play a role in buffering.

One end fixedly connected with first mount of base, the other end fixedly connected with second mount of base. One side of the first fixing frame facing the second fixing frame is respectively provided with a holding mechanism and a chest supporting mechanism, when a user uses the air resistance source intelligent waist twisting training device to carry out muscle training, the chest is leaned against the chest supporting mechanism, the holding mechanism is held by two hands, and the user can exert force conveniently. The gripping mechanism may include, but is not limited to, left and right grips 11 for gripping by both hands of a user.

The base is rotatably connected with a first rotating shaft, the first rotating shaft is respectively rotatably connected with a buttock supporting mechanism and an eccentric disc, and the eccentric disc is positioned between the buttock supporting mechanism and the base. One side of the hip supporting mechanism back to the second fixing frame is connected with a leg pushing mechanism. When the intelligent waist twisting training device using the air resistance source is used for carrying out muscle training, a user sits on the hip supporting mechanism, two legs are placed on two sides of the leg pushing mechanism, the chest leans against the chest supporting mechanism, and the holding mechanism is held by two hands. The user drives the leg pushing mechanism and the hip supporting mechanism to rotate by twisting the waist.

The eccentric disc and the hip support mechanism are respectively in rotational connection with the first rotation shaft, i.e. the eccentric disc and the hip support mechanism can respectively rotate relative to the first rotation shaft. When the base is in a horizontal state, the first rotating shaft is arranged along the vertical direction, and the eccentric disc and the hip supporting mechanism respectively rotate horizontally. The eccentric disc is fixedly connected with the hip supporting mechanism in an adjustable position, namely the eccentric disc and the hip supporting mechanism can synchronously and horizontally rotate, and when a user drives the hip supporting mechanism to rotate, the eccentric disc can be driven to rotate.

The base is connected with a pushing and stretching frame in a sliding mode, one side, close to the eccentric disc, of the pushing and stretching frame is connected with a roller in a rotating mode, and the roller is tightly attached to the eccentric disc. When the eccentric disc rotates, the roller can roll on the side surface of the eccentric disc to drive the push-extension frame to slide relative to the base. Referring to fig. 16, a second groove 22 is formed on a side of the eccentric disc 20 facing the pushing frame, when the leg pushing mechanism is not pushed by the user to rotate and the leg pushing mechanism is in the initial position, the roller 61 is located in the second groove 22, the distance between the first rotating shaft and the pushing frame is the minimum, the eccentric disc 20 is provided with a first rolling surface 23 and a second rolling surface 24, and the first rolling surface 23 and the second rolling surface 24 are symmetrically arranged on two sides of the second groove 22.
