A kind of muscle sports trainer

Abstract

A muscle sports trainer comprises a transverse first square tube. The upper part of each end of the first transverse tube is provided with a vertical second square tube which is fixedly mounted. The middle position of the inside surface of the second square tube is provided with a vertical long elongated guiding hole. A vertical tube is arranged outside each second square tube. The top surface ofthe first square tube is provided with second holes at positions which correspond with the lower end of the vertical tubes. The lower end of the vertical tube is fixedly connected with the upper end of the corresponding second through hole. The upper end and the lower end of the vertical tube are closed. The upper side and the lower side of the outer end of the elongated guiding hole are providedwith second transverse guide rails which are fixedly mounted. The second guide rails are vertical to the second square tube. A second vertical rod is arranged between two second guide rails on the same second square tube. Second slide blocks are mounted between the upper end and the lower end of the second vertical rod and the corresponding second guide rails. According to the muscle sports trainer, advantages in weight training are ingeniously combined with safety of a fixed appliance, thereby realizing a relatively high helping function on a trainee.

Description

technical field [0001] The invention belongs to the technical field of sports equipment, in particular to a muscle sports trainer. Background technique [0002] The most commonly used equipment for fitness trainers to train muscles such as shoulders, arms, and pectoralis major is dumbbells, barbells, Smith bench presses and other equipment. Dumbbells and barbells are for free weight training. In case of danger, the Smith bench press is a bench press completed on a fixed device. Since the grip bar on the Smith bench press frame is limited by the sleeve to move in the up and down direction, the grip bar is limited to be in a horizontal state all the time. To control the balance of the grip bar, you only need to push it to move up and down. The training effect is poor. When using the Smith bench press rack, when the strength is difficult to support the grip bar, you need to use the wrist to rotate the grip bar and hang the frame through the upper hooks at both ends of the grip ...

Problems solved by technology

[0002] The most commonly used equipment for fitness trainers to train muscles such as shoulders, arms, and pectoralis major is dumbbells, barbells, Smith bench presses and other equipment. Dumbbells and barbells are for free weight training. In case of danger, the Smith bench press is a bench press completed on a fixed device. Since the grip bar on the Smith bench press frame is limited by the sleeve to move in the up and down direction, the grip bar is limited to be in a horizontal state all the time. To control the balance of the grip bar, you only need to push it to move up and down. The training effect is poor. When using the Smith bench press rack, when the strength is difficult to support the grip bar, you need to use the wrist to rotate the grip bar and hang the frame through the upper hooks at both ends of the grip bar. This design has a great disadvantage. The shortcoming is that the trainer needs to turn the wrist to stop the grip bar from moving down. When the trainer bears a large longitudinal load on the wrist, it is easy to rotate the Wrist joints cause damage, which is not conducive to the safety of training
