Hold an object to feel the hands stay in sync
To train syncing the hands with the body on pitch shots, the speaker suggests holding an object so it doesn't drop while you swing: a towel under the armpits, an empty water bottle between the wrists, or a head cover held between the forearms. The goal is to keep the hands just holding the club in front of the chest, in sync with the body, rather than letting them work on their own.
