Abstract

A simple crunch exercise apparatus, using a fixed vest and a fixed barbell, and distributing weight to the chest, thereby easing a burden on arm muscles, and enabling an exerciser to select a larger weight range while still being safe.

Description

Simple abdominal curling training device

Field of invention

The invention relates to a simple abdominal curling training device, in particular to a device for performing abdominal curling training using a fixed vest, a barbell and a bracket.

Background technique

Abdominal curling is the most basic abdominal training. Many exercisers perform one or two hundred abdominal curling exercises every day. However, continued muscle growth relies on the principle of progressive overload (Principle of Progressive Overload), which requires constant weight increase. Most exercisers use their own weight to perform abdominal curling exercises, plus a certain angle (to raise the foot position through the supine board), can not achieve rapid abdominal muscle growth. Many beginners with no exercise experience can carry weight-bearing exercises with a weight of 15-20 kg at the beginning. Since the belly must bend the spine (so it is not suitable for weight-bearing vests), standard dumbbells / barbells are usually used to increase weight. This creates the following problems:

· Because the abdominal muscles are usually much stronger than the arm muscles, it is difficult for the individual trainer to move multiple dumbbells / barbells from the side to the chest, and it is not safe; a single dumbbell / barbell can be taken and then lying on the supine board. It is difficult to fix multiple dumbbells / barbells with fingers

· Because the movement is difficult and unsafe, the range of load that can be increased is limited

If you use dumbbells as a weight-bearing, because the weight-bearing has been installed once, it solves the problem of moving and fixing multiple dumbbells / barbells, but also because the abdominal muscles are usually much stronger than the arm muscles, it is difficult to hold it stably during abdominal curl training Dumbbells, and it is prone to uncomfortable abdominal curling training, and the arm is sore and unbearable, which makes it impossible to fully train the abdominal muscles.

Summary of the invention

If you use a barbell as a weight bearing, there is also the problem that it is difficult to hold it stably, and it is easy to have the problem that the arm is already too tired before completing the training. However, it is conceivable to set a focus point in the middle of the barbell rod, fix it in the middle of the chest of the practitioner, and set up a bracket (similar to a barbell bench press). The arm is only used to assist stability, which can reduce the burden on the arm muscles. At the same time, it also increases safety, allowing trainers to choose a larger weight-bearing range under the premise of safety, and better stimulate abdominal muscle growth.

The invention provides a simple abdominal curling training device, and its embodiments include:

· Fixed vest: In order to facilitate the bending of the upper body, the length of the vest is only down to the sternum. The vest has a locking structure in the middle, which can fix the barbell rod. The deadlock structure may be a soft structure, such as a tape.

· Barbell: To facilitate hand-holding, a curved barbell rod can be used.

· Bracket: Similar to the bench press bracket, supports the barbell before and after training.

However, it should be understood that the content of the present invention may not include all aspects and embodiments of the present invention, and the content of the present invention is not meant to be limited or restricted in any way, and the present invention disclosed herein will be understood by one of the following: Ordinary technicians include obvious improvements and modifications.

detailed description

The invention will now be described more fully below. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It is hoped that these examples will be provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

It should be understood that various changes can be made in the function and arrangement of elements without departing from the spirit and scope as set forth in the appended claims. Therefore, the embodiments are examples or implementations of the present invention, rather than the only implementations. The various appearances of "one embodiment", "an embodiment" or "some embodiments" do not necessarily all refer to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may also be provided individually or in any suitable combination. On the contrary, although the present invention may be described in the context of separate embodiments for the sake of clarity, the present invention may also be implemented in a single embodiment or in any combination of embodiments.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology and this disclosure, and will not be interpreted as idealized or excessive Formal meaning unless explicitly defined in this article.

Reference terms such as "left", "right", "top", "bottom", "front" and "back" are intended to be used in the implementation of the present invention with respect to the specific features, structures or orientations of the depicted embodiments example. Obviously, such directional terms with regard to the actual use of the device have no specific meaning, because the device can be used by the user or multiple users in multiple directions.

The fixed vest is used to distribute the weight of the barbell. If the barbell rod is directly pressed against the sternum, when the weight is too large and the trainer's bone density is insufficient, it may lead to fractures and even more serious concurrent injuries. Therefore, the fixed vest is from bottom to top, and the front side should contain the following structure:

· Cushion layer: It is closest to the chest of the trainer to cushion the pressure caused by the weight and enhance comfort

· Support layer: It is a whole support plate structure, distributing the load pressure to the buffer layer

· Locking structure: the barbell rod can be fixed so that it will not roll or fall

The fixed vest transfers part of the load to the shoulders and back through the shoulder strap. It should not be too loose, and at the same time, it must be easy to wear. Therefore, the shoulder strap and the back need to use synthetic fibers with sufficient strength and elasticity, or use a belt-like tightening design .

Some bench press equipment contains a safety design in case the fitness person is exhausted and the barbell falls and causes an accident. However, unlike the bench press with a vertical movement, the belly has a horizontal displacement, and a simple hook cannot solve the problem. A safety guide rail can be designed for the bracket. The height of the safety guide rail can be adjusted to extend toward the projection direction of the spine of the bodybuilder in the horizontal plane, and the distance from the supine board is greater than the body thickness of the bodybuilder. In this way, if the training weight exceeds the load range of the fixed vest, or due to negligence of the fitness person, the barbell rod is not completely locked to the fixed vest, the barbell rod slips off, and it will not hit the fitness person.

The above description is only an embodiment of the present invention and is not intended to limit the scope of the present invention. Various changes and modifications of the claims and the description according to the present disclosure are still within the scope of the claimed invention. Furthermore, each embodiment and claims may not necessarily include all the advantages or characteristics disclosed. In addition, the abstract and title are only used to facilitate the search for patent documents, and are not intended to limit the scope of the claimed invention in any way.
