Adjustable neck training traps: The neck training traps can be adjusted at the forehead, upper head, and under the chin, allowing a tailored neck workout that targets multiple angles. Additional Drings for complex movements: Drings on both sides of the ears and under the chin enable advanced exercises, such as horizontal neck extensions with weighted resistance. Improves neck and upper back strength: Neck training is beneficial for mixed martial artists, bodybuilders, weightlifters, boxers, kickboxers, and other athletes who want to strengthen the neck and upper back muscles, and it serves as an important tool for neck injury recovery. Stable and safe weight fixation: The adjustable head harness includes chains to fix the weight and midpoint Drings to keep the load centered, ensuring safety and stability during training and helping prevent injury. Use scenarios Scenario 1: In combatsports training (MMA, boxing, kickboxing) and strength programs, perform weighted neck extensions to build neck and upperback strength and improve overall neck stability during dynamic movements. Scenario 2: Neck injury recovery and rehabilitation programs, using controlled weighted exercises under proper guidance to progressively rebuild neck strength with secure weight fixation. Scenario 3: General athletic conditioning and performance work, integrating neck and upperback stabilization into routine workouts for bodybuilders and weightlifters to support posture and resilience during heavy lifts.
