Background

There are many exercise and fitness apparatuses available in the market, such as dumbbells or kettle bells or bar bells, and other load-bearing or weight-lifting apparatuses, which can be used for exercising arms, and there are many exercise and fitness apparatuses, dumbbells or kettle bells or bar bells, which can be adjusted to have different weights, so as to facilitate various people to exercise the muscles of the upper body of the user.

However, the weight adjusting mechanisms of the present weight-adjustable exercise device, dumbbell, kettle bell or bar bell are quite numerous and most of them are quite complicated, so that it is quite inconvenient to operate because a person needs a lot of procedures or actions or processes to adjust to different or required weights when operating or adjusting different weights.

In particular, the conventional weight-adjustable exercise device, dumbbell, kettle bell or bar bell each includes a plurality of weight plates inserted or mounted to the two ends of the long shaft in sequence so as to adjust the weight to different or desired weights. However, these weight plates are inconvenient to handle and use, and are unfortunately not particularly capable of some fine weight adjustment.

In view of the disadvantages of the conventional exercise device with adjustable weight, the present invention has been developed through many researches and improvements to provide an exercise device with adjustable weight, which can be adjusted to a proper weight.

It is an object of the present invention to provide an adjustable exercise device that can be fine tuned for weight and that can be operated and used inconveniently by, for example, a young girl with a small stature.
