Description

FIELD OF THE INVENTION The present application relates to the technical field of exercise equipment, and specifically to an exercise device. BACKGROUND OF THE INVENTION Dumbbells are a type of free-weight equipment widely used in fitness and strength training. It is mainly composed of a handle in the middle and weight blocks at both ends, wherein, the weight of the weight blocks at both ends can be adjusted, and the settings of different exercise intensities can be achieved by adjusting the weight of the weight blocks. When using dumbbells for exercise, the user's muscles actively contract against the resistance generated by the weight of the dumbbells to complete the predetermined action. During the confrontation process, the user's muscles can be stimulated to suffer minor damage, and the muscles become stronger during the recovery process, thereby achieving the purpose of exercise. At the same time, exercising with dumbbells can also improve muscle endurance and explosive power. When completing the predetermined action, the user controls the rotation of the dumbbell through hand and wrist movements; for example, the user can change the position or angle of the dumbbell through the rotation of the hand and wrist. During the process of controlling the rotation of the dumbbell through hand and wrist movements, if the user makes a mistake in controlling the dumbbell, it may cause accidental injuries to the user, such as muscle strains or tears, joint sprains or injuries and wrist injuries, etc. A number of devices have been published which provides user friendly dumbbell: “User friendly hand held weight”, U.S. Pat. No. 5,135,455, which disclose a user friendly dumbbell that is comfortable, safe and durable, and which also protects against damage to surfaces against which the dumbbell may come into contact is disclosed. “Fixed-head dumbbell”, Craig D. Landfair, U.S. Pat. No. 6,099,443, which discloses a pin passing through a bore in the weighted heads and each end of the bar holds the weighted heads securely in place. The weighted heads have a circumference of circular shape, and are coated with a resilient material. The exterior surface of the resilient material has a multi-sided circumference. The circular shape of the circumference of the weighted heads prevents the weighted heads from digging into the resilient coating when the dumbbell is in use or is dropped. There are other numerous prior arts, each to overcome a specific safety problem. Based on prior art then, no hand held device is available that offers safety and help uses improve their performance.
