[0001] The utility model relates to the technical field of fitness equipment, in particular to a motion component for guiding a barbell bar. Background Art
[0002] In the field of physical exercise and fitness, barbell training has always been a common strength training method used to increase muscle strength and physical fitness. Barbell training usually includes a series of movements such as squats, bench presses, deadlifts, curls, etc. These movements require accurate barbell guidance to ensure that exercisers can perform training safely and effectively.
[0003] The barbell is usually a long rod with weights on both ends, such as dumbbell plates or barbell plates. The exerciser must control the balance and movement trajectory of the barbell by himself, so many devices that can guide the barbell have been created, such as the Smith rack.
[0004] Among the existing barbell guide devices, there are basically only vertical guide devices. However, the direction of force exerted by human muscles is not simply up and down. The vertical movement method will require a certain amount of time for beginners to adapt before they can use it normally. In addition, when exerting force in the vertical direction, the degree of freedom of use is low, and only some muscle groups can be trained in a targeted manner. At the same time, the vertical pressure will cause the joints of the human body to bear greater pressure, and long-term use will easily lead to an increased risk of joint wear. Utility Model Content
