Wrist angles are critical in controlling the golf club and directly influence the clubface's orientation throughout the swing. Extension in the lead wrist opens the clubface, while flexion closes it. These variables affect shot direction, dynamic loft, launch angle, and compression. Your grip type can help you determine whether you need more extension or flexion in your lead wrist in your swing.
Strong grip players tend to display more lead wrist extension throughout their swing. A strong grip tends to influence the clubface to be more closed, so extension "opens it back up" if you will - allowing the player to keep the clubface relatively neutral. On the contrary, weak grip players tend to display more lead wrist flexion. A weak grip tends to influence the clubface more open throughout the swing, so flexion "squares it back up" - again, allowing the player to play with a relatively square clubface.
Radial deviation refers to the upward hinging of the club, while ulnar deviation refers to the downward hinging of the club. There are pros and cons to both movements in the golf swing, so matching them up with the rest of your pattern is crucial.
Forearm rotation comes in two forms: pronation and supination. If you pronate your lead arm, the clubface will open relative to the target. Conversely, supination with the lead arm helps close the clubface relative to the target.
