Double-wheel trunk extensors exercise machine

Abstract

The invention discloses a double-wheel trunk extensors exercise machine. The double-wheel trunk extensors exercise machine comprises a rack, a front wheel assembly and a rear wheel assembly are installed at the front side and the rear side of the rack respectively and are both provided with independent pedal assemblies, the pedal assemblies on the front wheel assembly and the rear wheel assembly are driven by hand force and foot force of an exerciser respectively, a horizontal soft cushion is fixed to the middle of the rack through a fixing rod, and under the condition of keeping the spine horizontal, the soft cushion is in contact with the waist and abdomen of the exerciser. Thedouble-wheel trunk extensors exercise machine has the advantages that since the self-gravity needs to be confronted, the trunk extensorsare continuously shrunk, in this way, the trunk extensorsare effectively subjected to resistance training, through riding motion of the two feet, the trunk extensors at the left side and the right side can be alternatively trained, not only is the training effect guaranteed, but also the trunk extensorsare not easily tired, the riding motion of the front wheel assembly cantrain the atissimusdorsi and the like, and a significant effect is achieved on keepingphysiological curve of the spine.

Description

technical field [0001] The invention relates to a body-building apparatus, in particular to a double-wheel lumbar and back muscle exercising apparatus. Background technique [0002] In the prior art, there is an airbag-type rectangular waist and back muscle exerciser, which inflates the airbag to support the human body overhead. This kind of waist and back muscle exerciser is limited by its shape. When it is over-inflated during use, The human body is directly overhead, and when the head, hands and feet are on the ground, the lower back cannot be lifted at the same time, and the exercise effect is poor, because the lower back muscles are in a relaxed state and have not been effectively and accurately trained, thus failing to satisfy the lower back muscle training and clinical treatment needs. [0003] There is also a kind of exerciser for the back muscles in the prior art. When in use, the airbag of the instrument is inflated so that the instrument is in the shape of an arc...

Problems solved by technology

[0002] In the prior art, there is an airbag-type rectangular waist and back muscle exerciser, which inflates the airbag to support the human body overhead. This kind of waist and back muscle exerciser is limited by its shape. When it is over-inflated during use, The human body is directly overhead, and when the head, hands and feet are on the ground, the lower back cannot be lifted at the same time, and the exercise effect is poor, because the lower back muscles are in a relaxed state and have not been effectively and accurately trained, thus failing to satisfy the lower back muscle training and clinical needs

[0003] There is also a kind of exerciser for the back muscles in the prior art. When in use, the airbag of the instrument is inflated so that the instrument is in the shape of an arch bridge. The exerciser lies on the top, and after persisting for a period of time, the airbag is deflated and the airbag is dry. , the arch bridge shape becomes a parallel structure, and the waist and back muscles are exercised repeatedly in this way. The problem with this method is that the human body is always in a relaxed state during the process of inflating and deflating the airbags, and no effective voluntary contraction has been formed. There is an upward movement during the inflation process, but this is caused by the airbag overcoming gravity. The low back muscles of non-exercises are formed by contraction, and the low back muscles are still in a relaxed state, which cannot effectively exercise the low back muscles.
