Portable exercise device for exercising biceps brachii muscles

Abstract

The invention discloses a portable exercise device for exercising arm muscles, particularly biceps brachii muscles, relates to the technical field of exercise equipment, and mainly aims at solving the problem that an existing exercise device for exercising biceps brachii muscles is inconvenient to use. The device comprises a bearing mechanism, rotating mechanisms and an elastic rope group. The rotating mechanisms are located at the two ends of the bearing mechanism and comprise handles, rotating shafts and short rods, the centers of the handles are connected to the bearing mechanism through the rotating shafts, the short rods are connected to the two ends of the handles, and the two ends of the elastic rope group are connected to one ends of the short rods at the two ends of the bearing mechanism respectively. The two hands or the backs of the two hands upwards grasp the handle in the rotating mechanism, and the wrist is forcibly rotated anticlockwise or clockwise till that the wrist cannot rotate so that the purpose of training the upper arm muscle groups such as the biceps brachii or the triceps brachii is achieved, and the device has the characteristics of simple structure and convenience in use; and the problem that an existing exercising device used for exercising biceps brachii muscles is inconvenient to use is solved.

Description

technical field [0001] The invention relates to the technical field of exercise equipment, in particular to a portable exercise device for exercising arm muscles, especially biceps brachii. Background technique [0002] The fitness equipment industry has come a long way in the past two decades, with many exercise machines catering to the growing number of consumers engaged in physical fitness activities. Arm strength refers to the force generated by the contraction and tension of the arm muscles, that is, arm strength. Arm strength training can effectively exercise arm muscle strength and shape beautiful upper limbs. Commonly used arm strength training equipment includes dumbbells, barbells, kettlebells, etc. With personal preference and people's requirements for personalized design are getting higher and higher. The biceps is responsible for elbow flexion and internal rotation of the forearm. It is the most common place for men to show strong muscles. It is like a business...

AI Technical Summary

Problems solved by technology

However, at present, sports equipment rarely has the function of comprehensive and targeted training for biceps brachii. For example, the most common barbell curl and dumbbell curl can only simulate elbow flexion and cannot simulate The biceps brachii undergoes the maximum contraction exercise, the convenience of use is poor, and the exercise effect is not obvious

[0003] The utility model CN201520494676 speed arm device can simulate the internal rotation of the forearm, and can train the biceps brachii to a certain extent, but the internal wear of the device is severe, and the damping is not constant. Strength adjustment is unreliable, inconvenient to use, and the exercise effect is not ideal
