1. Preface 

The arm refers to the upper limb, the part below the 

shoulder and above the wrist, sometimes including the hand. 

Physical exercise is a physical activity process with the 

purpose of developing the body, improving health, 

strengthening the physique and entertaining the body and 

mind by using various sports means and combining with 

natural forces. It is the main form of mass sports activities, 

which can promote the growth and development of the human 

body, cultivate the body-building posture and improve the 

working ability of the body, According to the characteristics 

of people's age and occupation, exercise can be carried out in 

a variety of ways, which can improve people's physical fitness 

and mental health, In addition to the common practice 

methods in teaching and training (including repetition method, 

transformation method, comprehensive method, circulation 

method and competition method), people have formed 

various fitness methods in long-term exercise practice.

4. Design Principle 

The working principle and application process of this 

design: when the design is in use, the knobs on both sides of 

the support base are slightly rotated outward, the contact end 

of the knob and the support rod are separated from each other, 

and the extrusion force disappears. The support rod is in an 

active state. Pull the support rod and grip rod outward, and the 

support rod and grip rod rotate outward, and the bottom side 

of the support rod fits with the No. 1 limit block at the center 

of the surface of one side of the support seat, No. 1 limit block 

supports and limits the supporting rod. The supporting rod 

and the holding rod are inclined at a certain angle, and the 

knobs on both sides of the support base are slightly rotated 

inward. The end of the knob and the support rod are squeezed 

each other, and the support rod is in a fixed state. The rotating 

plate at the upper end of the connecting seat is put down to fit 

the wall surface, the rotating shaft at the connection between 

the bottom end of the rotating plate and the connecting seat is 

rotated. The rotating plate turns to the bottom side, and the 

rotating plate is placed vertically with the wall. The bottom 

end of the rotating plate is connected with the No. 2 limit 

block at the center of the surface of one side of the connecting 

seat. The second limit block supports and limits the rotating 

plate. The rotating plate is used to place the training items and 

computers. The computer is the body to start the body and 

work, Remove the grip from the hook on one side of the upper 

end of the support rod, connect the hand with the arc groove 

at the rear end of the grip, pull the handle to one side, rotate 

the screw rod and rod groove through the rotating shaft of No. 

1 fixed base, turn the screw rod, rod groove, pull rope and grip 

to the front end, face the training personnel, stand at the center 

of the front end of the training device, and play the relevant 

training and teaching video files through the body, At the 

same time, the sensor and counter can monitor and count the 

trainers in the training process. Both hands pull the pull rope 

through the grip. The pull rope moves up and down in the rod 

groove and the upper end of the rod groove through the 

connecting block and the spring connected between the 

connecting block and the connecting block at the bottom end 

of the rod groove. Through elastic stretching, the arm muscle 

strength is trained. When the pull rope tension needs to be 

adjusted, the rod groove is rotated downward, It can be 

connected with the upper part of the screw rod by pulling the 

lower elastic force and groove between the screw rod and the 

upper part of the screw Rodin the middle distance and narrow 

distance push-up training, the hand can be held on the spring 

slot in the middle of the handle, and the hand fits with the 

spring block. By holding the elastic block before and after, the 

elastic block can stretch and stretch through the spring inside 

the spring groove to exercise the arm wrist force.
