Description
Technical Field
The invention relates to the field of fitness equipment, in particular to a weight-adjustable dumbbell.
Background
Dumbbell, Dumbbell, the name of English, an auxiliary device for weight lifting and body building exercises. Smaller than barbells. Light dumbbells may weigh 1, 2, 3, 5, 8, 12 lbs, 1 lb-0.4536 kg), etc. The weight of the heavy dumbbell is 10, 15, 30 kilograms and the like. The dumbbell is named because no sound is produced during practice. The muscle training device is used for muscle strength training and muscle compound action training. The dumbbell can be held by hands for patients with low muscle strength caused by paralysis, pain, long-term inactivity and the like, and the weight of the dumbbell can be used for performing resistance active exercise and training the muscle strength. Dumbbells can train a single muscle; if the weight is increased, the coordination of a plurality of muscles is needed, and the training can also be used as a muscle compound action training. The dumbbells generally used in the gymnasium are professional standard dumbbells, have large load and can be adjusted in a large range. However, in real life, the weight requirement of the dumbbell is not high, but the dumbbell is expected to have better convenience and certain adjustability. For example, the dumbbell is carried to outdoor grass, or an outdoor fitness place, some limb exercises are performed, and it is desirable to have a small weight load. If the traditional dumbbell is used, the carrying in and out is inconvenient, the burden is heavy, and the dumbbell is particularly not suitable for the old and women.
