Human Body Engineering: With an ergonomic Roman column handle, the jump rope grip is secure and nonslip. The design keeps the thumb in a natural position and allows the other fingers to bend without strain for a comfortable, secure hold. Durable construction: Nylon rope features olive-shaped PE beads, delivering break- and wear-resistance to withstand prolonged use. Adjustable design: Change the rope length by adding or removing beads on the cord. To adjust, untie the knot in the handle, reposition the beads as needed, and retie. The standard length is 2.6 m. Versatile use: Suitable for speed training in physical education, improving coordination and flexibility, and promoting athleticism in children. Indoor and outdoor workouts are supported, and the rope helps strengthen cardiopulmonary function. Use scenarios: - Speed and agility drills in physical education or training sessions. - Indoor or outdoor cardio workouts and interval training at home or in the gym. - Youth activity and family fitness to build coordination and athleticism.
