It is set to an optimal depth to ensure a firm grip, and to prevent sharp edges from hurting your hands. Similar to the depth, we also paid particular attention to the shape of the knurling, which has a significant impact on gripping ease, and designed the barbell to provide a firm grip.\u003cbr\u003e Furthermore, by working with manufacturers and factories to control quality by taking these points into consideration, we aimed to create a barbell that is affordable yet allows for effective training. \u003c\/p\u003e\n\n\u003ch2\u003e\u003cimg style=\"width: 100%;\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/user_data\/img\/ibs_2.jpg\" alt=\"The barbell collar \u0026quot;CL1\/4\u0026quot;, packed with IVANKO's know-how, is included as standard.\"\u003e\u003c\/h2\u003e\n\n \u003cp align=\"LEFT\"\u003eThe barbell collar \"CL 1\/4,\" packed with IVANKO's expertise, is included as standard. The popular \"CL 1\/4\" barbell collar, which many customers purchase separately, features a mechanism whereby a pressure ring inside the collar tightens when the screw is turned, securing the shaft with the pressure ring (surface) rather than the screw (point). The benefits of securing with a \"surface\" rather than a \"point\" are numerous, including increased holding power, less damage to the shaft, and less peeling of the shaft's anti-rust coating (typically chrome plating). This exceptional product was designed with the risk of rust weakening the steel and ultimately shortening the barbell's lifespan in mind. \u003c\/p\u003e\n\n\u003cp align=\"LEFT\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/fBnVKdJcOwI?si=QZhD_cq1MVM_Tlxl\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg style=\"width: 100%;\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/user_data\/img\/ib-pr.jpg\" alt=\"IVANKO's unique pressure ring mechanism for fixing force\"\u003e\u003c\/p\u003e\n\n\u003ch2\u003e\u003cimg style=\"width: 100%;\" src=\"https:\/\/fitnessshop.thinkfitness.jp\/user_data\/img\/ibs_3.jpg\" alt=\"Available in four sizes to suit your needs\"\u003e\u003c\/h2\u003e\n\n \u003cp align=\"LEFT\"\u003eThe optimal barbell varies depending on the exercise and equipment used (bench press stand, power rack, etc.).
