Your most effective method for a FLAT LEFT WRIST
 

For me I've had the most luck concentrating on maintaining the #3pressure point on short game shots, and feeling the right palm facing downward through impact on full shots (a tip from Johnny Miller in a 1998 Golf Digest article).

Impact Fix and Flying Wedges alignments.

Understanding them eliminates the need to 'do' things in your downswing to square up the face or to 'try' to keep a flat left wrist.

A lot of practice using Stage 1 and Stage 2 motions.

"Look, Look, Look" as Homer, Ted and Lynn would say.

Where should you be looking hold your follow through and check that wrist!

Great question!

For me:

Hitting down!
