Description

TECHNICAL FIELD The present disclosure relates to a muscle training device. More specifically, the disclosure relates to a muscle training device as defined in the introductory parts of claim 1. BACKGROUND ART Training the arm muscles, e.g. biceps and triceps, can be performed in many ways. One of the popular techniques is to focus on keeping the elbows in a fixed position which isolates the specific muscles. By isolating a specific muscle, said muscle can be trained with less weight, having the same or improved gain as using a heavier weight. There is a number of products on the market aiming to assist a user to keep the elbow in the desired fixed position. Commercial gyms have specially adapted machines and/or specially designed benches. However, there exist smaller devices, e.g. the so called "arm blaster". An arm blaster keeps the arm of the user in a fixed position against the trunk of the user, with the object being that this promotes proper form while also isolating the biceps.

A problem with the solution of the prior art is that the arm blaster, despite that it is smaller and cheaper compared to the specially designed benches, is still bulky and not user friendly. For example, the arm blaster cannot be packed within a gym bag, and the arm blaster it is somewhat difficult to adjust to suit the body of the user. lt may feel uncomfortable. There is thus a need for an improved product. SUMMARY lt is an object of the present disclosure to mitigate, alleviate or eliminate one or more of the above-identified deficiencies and disadvantages in the prior art and solve at least the above mentioned problem.

This has the advantage that the biceps muscles are isolated. The user simply put her/his arms through the loops, with the centre part positioned on the front side of the upper body of the user. The inelasticity of the centre part prohibit the elbows to drift apart. Further the length L and the width W of the centre part are designed to be functional and comfortable for the user of the muscle training device. The length L need to be long enough to separate the elbows from each other, still short enough to obtain a tight fit preventing the elbows to move backwards. The width W, need to be wide enough to reduce pressure on the front side of the upper body of the user, still not too wide leading to bad fit in relation to the body of the user. According to some embodiments, the width w of each end portion is at least 30 mm. According to some embodiments, the width w of each end portion is at least 40 mm.

According to some embodiments, the width w of each end portion is not more thanmm.

According to some embodiments, each of the bands defining the loops has a length I in the range of 400-600 mm.

According to some embodiments, each of the bands defining the loops is elastic in its longitudinal direction. This has the advantage that the loops fit a wide range of arms in different sizes, and is easy to use since no advanced setup is needed.

According to some embodiments, the bands defining each loop has a neopren rubber layer attached on the inner periphery of each end portion defining the first and second loop.

According to some embodiments, the neopren rubber layer has a thickness in the range of 3-7 mm.

According to some embodiments, the length L of the centre part is at least 200 mm.

According to some embodiments, the centre part formed by one single continuous band.

According to some embodiments, the centre part comprising a first and a second edge attached to the first and second end portion respectively.

According to some embodiments, the centre part further comprises a flexible sheet having a substantially rectangu|ar shape, with two opposite longer edges with a length L', and two opposite shorter edges with a width W', and wherein the bands defining the respective loop extend from opposite shorter edges. This has the advantage of an improved comfort and user friendly fit.

According to some embodiments, the length L' of the sheet is equal to or less than the length L of the centre part, and the width W' of the sheet is equal to or greater than the width W of the centre part, and wherein the sheet is attached to a surface of the centre part.

According to some embodiments, at least one of the two opposite longer edges of the sheet is substantially convex, such that the sheet has a maximum width located substantially in the centre of the sheet and a minimum width located substantially at the two opposite shorter edges of the sheet. This has the advantage of improved comfort and user friendly fit, since the flexible sheet, is designed to alleviate pressure during the use of the training device originating from the weight(s) used by the user while using the device. ln other words, the user will not feel discomfort to the front side of the upper body because neither the top edge nor the button edge of the sheet and the centre part is forced against the front side of the upper body.

According to some embodiments, the centre part of the muscle training device comprises any of neopren rubber, nylon, polyester, low-density polyethylene and/or evafoam, or a combination thereof.

The training device 100 keeps the arms of the user in a fixed position against the front side of theupper body of the user. The training device 100 comprises a plate 102, having two outer ends 104, and a strap 106. The strap 106 is sometime adjustable by adjustable means 106a. The plate 102 is often made of lightweight rigid material, e.g. aluminum. The strap 106 goes around the neck of the user. The two outer ends 104 aim to receive the elbows of the user and keep the position of the elbows in a substantially fixed position. ln some embodiment, training device 100 comprises an inner surface 108, a neck brace 110 (not shown in Fig.1a). The two outer ends 104, the inner surface 108, the strap 106, and/or the neck brace 110, may be padded with a soft material, e.g. neopren.

Fig. 2a illustrates an exemplary embodiment of a muscle training device according to a first aspect of the disclosure. Fig. 2a illustrates a perspective view of the muscle training device The muscle training device 200 comprises muscle training device 200, comprising a first and a second end portion 202a, 202b, and a centre part The centre part 204 is forming a flexible support part which is substantial inelastic in its longitudinal direction. The centre part 204 comprises a first and a second edge 204a, 204b attached to the first and second end portion 202a, 202b respectively. The centre portion 204 has a length L of 425 mm and a width W of 40 mm. The first and second end portion 202a, 202b comprises a first and second band 206a, 206b defining a first and second loop 208a, 208b. Each of the bands 206a, 206b defining a loop has a length I of 425 mm and a width w of 55 mm. ln the illustrated embodiment, the length I of each band 206a, 206b is the total length of the band, which length also constitutes the circumference of the loops 208a, 208b formed by the band.

The bands 206a, 206b defining the loops are elastic in their longitudinal direction.
