A kind of arm strength fitness equipment that adjusts the weight according to the degree of curling

Abstract

The invention discloses an arm strength fitness equipment that adjusts weight according to the bending degree. The structure comprises a height and weight adjusting device, a cantilever beam, a steering wheel, a fixed adjusting rod, a rope, an adjusting connecting block, a connecting bolt, and a handle. The upper end of the height and weight adjusting device and the right end of the cantilever beam are fixed by the bolt, which has the beneficial effect that, in the later arm training, the weight control bolt and the weight connecting block can cooperate with each other to reduce the weight ofthe iron blocks in the second half of the arm bending process, so that the arm bending of will be completed, thereby improving the degree of contraction of the arm muscles during the bending, which leads to a better exercise effect by making the muscle peak of arm muscle more prominent. When an iron block is separated, it can be fixed in the air under the action of the suspension anti-drop device, so as to avoid damaging the equipment by falling blocks after weight reduction.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to an arm strength fitness equipment whose weight is adjusted according to the degree of curling. Background technique [0002] Arm strength fitness equipment refers to the force that can exercise the contraction and tension of the arm muscles, that is, the strength of the arm, and at the same time can exercise the muscles of the arm so that the arm muscles can be exercised. When exercised to a certain extent, the muscles can be Get the pump. [0003] However, the weight of traditional arm strength fitness equipment is generally fixed in the process of exercising. When the arm curls upwards from the bottom to the top, the strength gradually decreases. If the weight is reduced and the weight remains the same, it is easy to make it difficult to complete the whole curling action, which reduces the degree of contraction of the arm muscles and reduces the exercise effect of the arm musc...

Problems solved by technology

[0003] However, the weight of traditional arm strength fitness equipment is generally fixed in the process of exercising. When the arm curls upwards from the bottom to the top, the strength gradually decreases. If the weight is reduced and the weight remains the same, it is easy to make the whole curling movement difficult to complete, which reduces the degree of contraction of the arm muscles and reduces the exercise effect of the arm muscles, resulting in relatively less prominent muscle peaks of the arm muscles.
