Description

technical field [0001] The invention relates to a physical fitness device, in particular to a parallel bar arm strength fitness device with good adaptability. Background technique [0002] So far, the single and parallel bars, as two kinds of exercise equipment, are generally fixed and installed outdoors, so people often see people exercising their arm strength outdoors, while outdoor parallel bars exercise is less safe, and many exercisers do not have enough arm strength to support them at the beginning. The body is upward, so that the arm is easily injured when exercising, and the exercise effect is relatively poor, and the double poles cannot be adjusted and cannot be adapted to the exercise of people of different heights. Contents of the invention [0003] The object of the present invention is to provide a parallel bar arm strength fitness device with good adaptability, so as to solve the problems raised in the above-mentioned background technology. [0004] To achie...
