A kind of abdominal muscle wheel auxiliary device

Abstract

The invention provides an abdominal muscle wheel aid. The abdominal muscle wheel aid comprises two U-shaped rubber band grooves, at least one annular rubber band, two clamping sleeves, a transverse shaft, two bent shafts and two slipper-shaped components, wherein the two U-shaped rubber band grooves are symmetrically formed in the same straight line; at least one rubber band groove body for placing an annular rubber band is formed in each U-shaped rubber band groove; the annular rubber bands are inserted in the rubber band groove bodies in the corresponding sides on the two U-shaped rubber band grooves; each clamping sleeve is arranged on an end surface of the corresponding U-shaped rubber band groove; a shaft wheel and the transverse shaft respectively penetrate through the corresponding U-shaped rubber band grooves; the two bent shafts are respectively arranged at two ends of the transverse shaft; the two slipper-shaped components are respectively arranged at free ends of the bent shafts. According to the abdominal muscle wheel aid, the rubber bands are not rolled when a main wheel is pulled back, the tightening and releasing power is adjustable, feet of a user do not need to be fixed on the ground, and unnecessary power loss of a user is avoided.

Description

technical field [0001] The invention relates to training equipment for physical exercise, in particular to an abdominal muscle wheel assistant. Background technique [0002] At present, the existing products on the market include single-roll ordinary ab wheel, double-roll ordinary ab wheel, rebound type ab wheel and pull-cord ab wheel with brake, single-roll ordinary ab wheel and double-roll It is very difficult for a person who has not trained for a long time to do a complete movement when doing the whole movement of the ordinary abdominal muscle wheel. At the beginning, due to insufficient strength, it is very easy for the face to touch the ground when doing the movement; the rebound type Although the abdominal muscle wheel and the pull rope type abdominal muscle wheel with brakes solve the problem that some beginners cannot fully perform the complete movement due to insufficient strength, but because the reduced force for beginners is a fixed value that cannot be adjusted...

AI Technical Summary

Problems solved by technology

[0002] At present, the existing products on the market include single-roll ordinary ab wheel, double-roll ordinary ab wheel, rebound type ab wheel and pull-cord ab wheel with brake, single-roll ordinary ab wheel and double-roll It is very difficult for a person who has not trained for a long time to do a complete movement when doing the whole movement of the ordinary abdominal muscle wheel. At the beginning, due to insufficient strength, it is very easy for the face to touch the ground when doing the movement; the rebound type Although the abdominal muscle wheel and the pull rope type abdominal muscle wheel with brakes solve the problem that some beginners cannot fully perform the complete movement due to insufficient strength, but because the reduced force for beginners is a fixed value that cannot be adjusted, some strength is insufficient For beginners, the movement is still relatively difficult during the training process. Because the strength of retraction and release is not adjustable, the space for progress of the practitioner is very slow, and the dependence is particularly strong. Pulling the rope type abdominal muscle wheel, if the rope is pulled during the exercise One end is fixed on the foot. When doing sports, in order to prevent the pull-back main wheel from hitting the rubber band, the athlete's legs have to be spread at a large angle. If it is fixed on the thigh or calf when doing sports, use The patient exerts a lot of force on the legs, and it is very uncomfortable to tighten the leg muscles

Therefore, the common problem of the abdominal muscle wheel is that the structure is single. During the exercise, the user's feet need to be fixed to the ground, which is easy to consume unnecessary strength.
