What does the "first pull" in the clean involve?

The "first pull" in the clean is a critical phase of the lift that involves lifting the barbell from the ground to knee height. This phase is essential as it sets up the position and trajectory for the subsequent movements in the clean. During the first pull, the lifter must maintain a strong back angle and use their legs to initiate the lift, while also properly engaging their core and keeping the bar close to the body. This ensures an efficient transfer of force from the legs to the barbell, which is crucial for the success of the full clean. Understanding this phase helps athletes emphasize technique and strength in their training leading up to the second pull and the catch position.
