Description

Light weight plate

technical field

The utility model relates to a light-weight weight-lifting plate, in particular to a weight-lifting plate with a large diameter that reduces the probability of waist injury of a lifter.

Background technique

In order to exercise the lines and endurance of muscles, people will use some sports equipment for weight training, such as: barbells, dumbbells, etc., as far as barbells are concerned, weight-lifting plates are installed on both sides of a long metal cross bar. With different weights, users can choose weight-lifting plates of appropriate weight for weight-lifting exercises. The weight-lifting plates are cast metal components, and the larger the weight, the larger the diameter. Among them, lightweight weight-lifting plates, such as 5 kg, 2.5 kg The kilograms have diameters of 21.5 centimeters and 16 centimeters, respectively.

When beginners or users with insufficient muscle strength perform weightlifting training, they will start with lightweight weightlifting sheets first, and gradually increase the weight of the weightlifting gradually. The distance between the crossbar and the ground is about 8-10 cm. When the user bends down to grasp the crossbar for clean and jerk, because the distance between the crossbar and the ground is close, it is difficult for the user to perform the clean and jerk action, and it is easy to cause the user to use it. Therefore, how to increase the diameter of the lightweight weight lifting plate and increase the distance between the bar and the ground to further improve the user's exercise safety is a problem that the industry is currently thinking about.
