I. The working principle of the power-assist belt
In training, many people affect the main training because of insufficient grip strength. The wrist and forearm are relatively small muscle groups, which are easily exhausted, and their strength is far worse than that of the latissimus dorsi and rotator cuff muscles. When the back is still very strong, the arm is the first to withdraw the gun. In this case, you can use the power belt to increase the grip strength.
The principle of the power assist belt is to tie the appliance through the rope, so that the load is directly applied to the forearm, and the force is not dispersed. This allows for better training of the back. There will also be no situation where the back has not been practiced and the forearm is exhausted first.
Second, What exercises can the belt help with
The first one is the pull-up, which is a very classic back training exercise, but not many people can actually do a few sets. For amateur trainers, many people are obviously insufficient in weight or strength, and the help of power belts is a good method.
Deadlift is also one of them. You will find that not only amateur trainers, but also professional training will use power belts when challenging heavy weights.
In addition, booster belts are actually used in training such as high pull-downs and rowing.
Three, when to use power belts
Strictly speaking, powerlifting competitions are not allowed to use power belts, and there are no restrictions on strongman competitions. Therefore, professional players generally use power belts when they hit heavy weights in training, and they will not rely too much on them. Because the frequency of use is too high, it will indeed limit the improvement of the strength of the wrist flexors and extensors.
For ordinary fitness practitioners, it is recommended to consider using it in the following situations.
1. Use heavy weights frequently in a short period of time, at least 50 percent of the maximum weight.
2. Insufficient grip strength affects training efficiency. For example, in deadlifts and other movements that target back muscles and leg muscles, the grip strength is always insufficient first, resulting in the inability to perform the movement and effectively targeting the target muscle group.
Notes: The lifting belt is usually not used because it is wrapped around the wrist and the bar at the same time. Whether the barbell is lowered normally or the action fails, it may cause the barbell to be unable to be released in time. The consequences are very serious.
