Abstract

The invention discloses a pull-up muscle group recession exerciser. The pull-up muscle group recession exerciser comprises a rack (1), wherein the rack (1) is provided with a bench table (2), the bench table (2) is also provided with a thigh fixing sleeve (3), a handle (4) is arranged above the thigh fixing sleeve (3) and connected with one end of a steel wire (5), and the other end of the steel wire (5) sequentially passes through a first pulley (6), a second pulley (7) and a third pulley (8) to be connected with a hoisting machine (9) with adjustable speed; the steel wire (5) positioned between the second pulley (7) and the third pulley (8) is also provided with a stroke contact (10); and an upper stroke switch (11) and a lower stroke switch (12) are respectively arranged above and belowthe stroke contact (10). The pull-up muscle group recession exerciser disclosed by the invention has the advantages of being simple in structure, capable of meeting training requirements for different intensities, high in training efficiency and high in safety.

Description

technical field [0001] The invention relates to a body-building training device, in particular to a pull-up muscle group retreat exerciser. Background technique [0002] Pull-ups mainly exercise the back and hand muscles of the body, and are one of the important reference standards and items for measuring physical fitness. It is a strength test item for middle school and college physical education classes in our country. Current pull-ups are mainly the human body as the active force-applying subject, and its training is mainly to overcome self-gravity suspension strength training, and utilize various training apparatuses that overcome resistance and contract to the heart. When people are exercising, the muscle contraction is mainly eccentric contraction and concentric contraction. Most of the fitness equipment at this stage is exercised through the concentric contraction of the muscles, while ignoring the exercise of muscle strength through eccentric contraction. Cardiac c...
