GPR HMS is a straight bar with star-shaped locks. The grip is carefully textured to ensure a secure and comfortable hold. The set includes two locks. This type of locking mechanism ensures a stable position of the weights on the barbell during exercise. The nuts have rubber seals to prevent loosening. Part of the bar is threaded, allowing for quick and secure weight attachment. The barbell is made of steel. It has a diameter of 3 cm, making it very stable and comfortable. The chrome coating guarantees that it will maintain its appearance over a very long lifespan and also provides the best protection against rust.
