Introduction for speed arm apparatus: Exercise muscle power and muscle endurance by quickly punching. The training effect is very good, surpassing the vast majority of training equipment on the market.

Introduction for Resistance adjustment Speed arm apparatus: Based on the original function, 

the mechanical damping effect is added, which breaks through the original functional limitations and is upgraded to an adjustable resistance design. After the muscles adapt to a certain amount of training intensity, the effect will be significantly reduced. This speed arm can perform the training without resistance and increase the resistance, which greatly improves the training effect.

How to adjust the resistance: By rotating the middle screw, you can adjust the resistance of the corresponding steel wheel. Turn outward to reduce the resistance. If you increase the resistance, the resistance adjustment is a fine adjustment process. Do not screw the screw to the tightest or Screw down (to avoid spring pop-up) and turn the steel wheel during adjustment to check if the required strength is reached.

Daily maintenance and common problems: The surface of the speed arm is made of the latest chrome plating process, the surface is white and silver, the coating is thick, and it is not easy to rust. However, it also needs daily maintenance. For example, if there is more sweat in summer, after training the equipment, the handle can be wiped with a dry towel, which can effectively prevent rust and prolong the service life. Because the internal structure is more complicated than the traditional ordinary speed arm, the factory has added high temperature resistant solid butter and mechanical lubricating oil. If you receive the baby, it will be normal to have oil spill on the edge during the initial practice. Don't worry about damage and wear. Towel wipe the edge ring) This is a running-in process, please feel free to use it. After a period of time, the mechanical oil will not penetrate the inner ring. You can exercise more often, the effect is better, because the butter stability is very good, you don't need to Add to.

Training method:

Method 1: High-speed arm, slightly over-headed, quick punch, practice deltoid, latissimus dorsi, trapezius. 

Method 2: Lift the speed arm quickly, punch out quickly, practice biceps, triceps, forearm muscles.

Method 3: Place the speed arm on the ankle, bend it forward slightly, turn it for a long time, practice muscle coordination, muscle endurance.

5 groups per day, each group 100-200 times high speed, the effect is very good. Each group is separated by 15-20 seconds.
