Zhang Kong Training Collars Overview Zhang Kong Training Collars are built for daily Olympic weightlifting training, offering the same precision and durability found in competition models but in a more practical structure suited for frequent use. Each collar is engineered to secure plates firmly during dynamic lifts, helping maintain barbell balance through repeated snatches, clean & jerks, and accessory pulling work. With a stable locking mechanism and smooth tightening action, the collars prevent plate movement even during high-volume sessions or fast technical drills. Their durable construction stands up to continuous training in clubs, performance gyms, and advanced home setups—making them an essential tool for athletes who want reliable, calibrated weight control every day.
