Description

Technical Field

[0001] This utility model relates to the field of dumbbell technology, and more specifically to a fall-proof fitness dumbbell. Background Technology

[0002] Dumbbells are a multi-functional fitness tool that can effectively train all muscle groups in the body by adjusting the weight and designing the movements, thereby improving strength, coordination and function. Its core value lies in its high flexibility and wide applicability, making it suitable for people of different fitness levels. It can be used to build muscle and shape the body, as well as improve basic motor skills.

[0003] Current technology has shortcomings: dumbbells are prone to slipping out of the user's hands during training and injuring them. Beginners in gyms without a coach are also prone to dropping dumbbells, causing damage to the ground or the user. Furthermore, most dumbbell plates are circular, with their center of gravity in the center of the dumbbell, making them prone to rolling. However, due to the weight of dumbbells, collisions during rolling amplify the damage. While some polygonal dumbbell plates prevent the dumbbells from rolling, the polygonal structure has sharp edges, which can cause greater damage when dropped. Utility Model Content
