This is a training jump rope that uses the weight of the rope itself, rather than having weights in the grips. The total weight is approximately 480g. 【10mm Diameter Heavy Rope】Because it is considerably heavier than a regular jump rope, it puts more stress on the wrists, arms, shoulders, and core, efficiently improving muscle strength in a short amount of time. Made of abrasion-resistant PVC material, it is durable and long-lasting, and the rope is less likely to twist, allowing for stable jumping. The grips have a bearing structure for smooth rotation. Easy-to-grip handles. Grip length: approximately 16cm / Grip diameter: 3.5cm. *The grips are made of wood-grain PP material, not wood. Total length: 300cm. The length can be easily adjusted.
