Abstract

The invention relates to the technical field of fitness equipment, and discloses a counting chest expander device for fitness, which comprises a shell, the upper end and the lower end of the left sideof the shell are each provided with a motion shaft fixing base, the two ends of each motion shaft fixing base are each provided with a fixing base sliding groove, and each motion shaft fixing base isprovided with a rotating structure. A speed reduction structure is arranged in the shell, and a hand pinching prevention device is arranged on the upper side of the shell. The device has the advantages that the arc-shaped hand pinching prevention device is arranged, so that the force generated by sudden rebound of the holding rod can be buffered; the speed reducer is arranged, so that the exercise stress of people is increased, and the effect brought by fitness is improved; and the counting device is arranged, so that the exercise amount is standardized for body building.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a counting tensioner device for fitness. Background technique [0002] Fitness is also an exercise method that many men and women use to shape a perfect body. The flexion and tension of the arm is a good way to exercise the arm. At this time, a tensioner is needed as a fitness auxiliary equipment to exercise the arm. The tensioner is a suitable for The benefits of using a stretcher as a popular fitness exercise device are: the biceps is a muscle with two muscle heads, and its main function is to bend the arms. When you bend your arms, you also use another muscle—the triceps. [0003] The current tensioners are generally spring tensioners and tape tensioners. When exercising, one end of the tensioner should be firmly fixed on other objects. If it becomes smaller, the tensioner may slip off or bounce back suddenly, causing injury accidents. At the same time, the skin or...
