bench press dumbbell

Abstract

The invention relates to a benching dumbbell. The benching dumbbell comprises a rod body, and sleeve tubes are arranged at the two ends of the rod body; limiting rings are fixedly arranged at the opposite two ends of the two sleeve tubes, and detachable fastening rings are installed at the rear ends of the two sleeve tubes; dumbbell pieces are installed between the limiting rings and the fasteningrings; a regulating frame is slidably arranged in the center of the rod body, and the regulating frame can only perform reciprocating parallel moving in the radial direction of the rod body; elastictelescopic columns are symmetrically arranged on the outer frame walls of the regulating frame, and limiting units of all elastic telescopic columns are installed on the inner frame walls of the regulating frame; the limiting units are opposite to the rod body; balanced hoods are fixedly arranged at the front ends of the sleeve tubes, wedge oblique surfaces are in contact with the elastic telescopic columns. The dumbbell has the advantages of unique principal, a trainee can be assisted to perform standard benching practice, and the trainee can be effectively reminded to prevent the unbalance in left and right in practice to help the trainee in obtaining a uniform and aesthetic body shape through exercising.

Description

technical field [0001] The present invention relates to a kind of sports fitness equipment, especially a kind of dumbbell. Background technique [0002] Dumbbells are one of the commonly used equipment for sports and fitness equipment. Dumbbells are small in size and flexible in operation, which can meet people's diverse training needs; when performing chest muscle training, one of the actions is dumbbell bench press, which requires the trainer to lie flat on the bench press On the board, hold the dumbbells with both hands and lift them up and down repeatedly. During the lifting process, keep the arms slightly bent. The difference is that the degree of difficulty in weightlifting is different, so the dumbbells are often lifted asymmetrically during training, and the two dumbbells are tilted to one side, resulting in non-standard exercise movements, which eventually lead to asymmetrical muscle training. One side of the chest muscle is large and the other side is small , affe...
