What must a lifter do before starting the deadlift?

Before starting the deadlift, it is essential for the lifter to ensure that the barbell is positioned correctly and that their grip is secure. This step is critical for both safety and performance. Proper barbell positioning means that the lifter can effectively engage their muscles and lift the weight without unnecessary strain or risk of injury. Ensuring a secure grip is equally important, as it stabilizes the lifter's hold on the barbell and helps prevent slipping, which could lead to loss of control during the lift. Therefore, focusing on these aspects helps in executing the lift effectively and safely within the guidelines established by the International Powerlifting Federation.

Other options such as performing a warm-up set, consulting the chief referee, or signing a waiver may be relevant in different contexts but are not prerequisites specifically required before starting the deadlift in a competition setting.
