The invention provides a
pectoralis major muscle training device and belongs to the field of sport equipment. The
pectoralis major muscle training device comprises rotating arms, a rack, a
rope, single pulleys and a dual-
pulley, wherein the upper portion of the rack (1) is connected to a weight block (4) through one end of the
rope (3), the other end of the
rope (3) is connected with a support of the rotating arms (5) to form a whole through the dual-
pulley (2) on the upper portion after bypassing the single pulleys (6), the pulleys below the rotating arms (5) are installed on one side of the rack (1) through screws after bypassing the rope (3), and a seat (6) is installed on the middle position of the rotating arms (5). In use, a person sits on the seat, the two hands push the rotating arms outward hard, the single pulleys and the dual-
pulley are driven to rotate through the rotating arms, the rope is driven to conduct upward traction, the weight block is made to move up and down repeatedly, and therefore the purpose of training the strength of the
pectoralis major muscle and the
upper limb muscles is achieved. The strength of the big arm muscles and the coordination between the body muscles and the body are achieved through training. The pectoralis major
muscle training device has the advantages that the structure is simple, the volume is small, the training is not limited by the field and the time, the carrying is convenient, the operation is easy, the application range is wide, and therefore the pectoralis major
muscle training device is the necessary health and fitness facility for professional sport teams and communities.
