Description

TECHNICAL FIELD

[0001] The utility model relates to physical training equipment technical field, concretely relates to a back muscle training device for physical training. BACKGROUND

[0002] The back muscle training device mainly exercises the latissimus dorsi, trapezius, deltoid and biceps brachii, can improve the body back muscle strength, enhances the back muscle and abdominal muscle ligament stretch, strengthens the coordination ability of back small muscle group, increases the back muscle movement flexibility and flexibility.

[0003] In the special training of sports, the trainer needs to simulate the actual movement characteristics of the specific project as much as possible to train the key muscle groups on the basis of safety to improve the training results. For example, in the training of sports projects such as kayaking and breaststroke, the sitting posture and the prone posture are adopted respectively to strengthen the targeted training of the back muscles of the trainer, which is more conducive to improving the results of the corresponding project.

[0004] The existing common back muscle training device for physical training includes barbells and gantry comprehensive training devices. Although these devices have multiple training methods, they are not suitable for the training of some special sports such as kayaking and breaststroke, and it is not easy to improve the results of some sports projects.

[0005] The Chinese patent with the application number CN202120349797.1 discloses a tension back muscle training device for physical education, which comprises a rear foot and a main base frame. The rear foot is provided with a main base frame at the front middle position. The main base frame is provided with a seat cushion at the front end upper position. The main base frame is provided with a shoe cover at the both sides positions. The rear foot is provided with a rear column frame at the front middle position, and the rear column frame is located at the rear end of the main base frame. The rear column frame is provided with a front column frame at the front position, and the front column frame is located on the main base frame. The overall material is set as a 2.5mm thick steel frame, so that the device is more solid and stable. The front end of the adjustable support pipe is connected with the adjustable backrest, and the adjustable backrest can rotate by 270 degrees. By adjusting the adjustable backrest, students can have a more comfortable posture during training to obtain better training results.
