Improved fitness bar

Abstract

The invention discloses an improved fitness bar. The fitness bar comprises a bar body, the bar body is slidably sleeved with two holding sleeves, limiting grooves formed in the axial direction of theside wall of the bar body are formed in the bar body, limiting sliding blocks corresponding to the limiting sliding grooves are fixedly connected with the inner walls of the holding sleeves, the limiting sliding blocks are slidably connected in the limiting sliding grooves, piston cavities are formed in the holding sleeves, air bags fixedly sleeve the side walls of the holding sleeves, the air bags are communicated with the piston cavities, piston rods which can be horizontally moved are slidably connected with the interiors of installing grooves, installing grooves which are formed in the axial direction of the bar body are formed in the side wall of the bar body, multiple straight gears are equidistantly and fixedly connected with the inner walls of the installing grooves, accommodationgrooves are formed in the side walls, close to the bar body, of the piston rods, and abutting pressing mechanisms cooperating with the straight gears are arranged in the accommodation grooves. By means of the fitness bar, hand gripping force exercise can be conducted while arm weight bearing exercise is conducted, the weight born by the arm is gradually increased when exercising is conducted, andthe exercising effect is better.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an improved fitness bar. Background technique [0002] In the field of fitness, there are many fitness equipment for exercising arm strength, such as barbells, dumbbells, tension machines, and arm strength machines. However, dumbbells and barbells are generally fixed weights, and they are generally lifted directly or for a certain amount during exercise. Weight-bearing, this kind of exercise method exerts force on the muscles at one time, which may easily cause muscle strain, or cause the muscles to produce a large amount of lactic acid, making the whole body sore after exercise, and if you want to adjust the weight of the arm exercise, you need to readjust the weight of the barbell or dumbbell. The operation is more troublesome. [0003] After retrieval, Chinese Patent Publication No. CN105561531B discloses a fitness bar, which discloses a method of adjusting the self...

Problems solved by technology

[0002] In the field of fitness, there are many fitness equipment for exercising arm strength, such as barbells, dumbbells, tension machines, and arm strength machines. However, dumbbells and barbells are generally fixed weights, and they are generally lifted directly or for a certain amount during exercise. Weight-bearing, this kind of exercise method exerts force on the muscles at one time, which may easily cause muscle strain, or cause the muscles to produce a large amount of lactic acid, making the whole body sore after exercise, and if you want to adjust the weight of the arm exercise, you need to readjust the weight of the barbell or dumbbell. Operation is more troublesome

[0003] After retrieval, Chinese Patent Publication No. CN105561531B discloses a fitness bar, which discloses a method of adjusting the self-weight of the base bar to the arm force arm by rotating the holding tube. , due to the rotation of the wrist, the exerciser's two arms and the body will shake to a certain extent when using it, which is not conducive to the balance of the exercised arm, and then affects the effect of arm strength exercise; The upper muscle group plays the role of exercise, and the exercise part is relatively single, so it is difficult to achieve the desired effect
