The way to learn any new swing is through hitting half-swings. Here are the benefits: (1) Less to go wrong (most errors in the golf swing happen in the full swing), (2) Build your golf muscles (hitting half-swings will not be easy because, even if you've played a lot of golf, you haven't developed these important muscles), (3) Hitting power comes in the half-swing area (if you try to hit hard from the top of the full swing, you might hit left, hit a big slice or miss the ball entirely), (4) You have to learn how to hit the ball hard (smooth syrupy golf swings are Pro Only), (5) You warm up on the practice range with half swings, (6) amateur golfs should at most, swing with a 3/4 swing to retain control and from 1/2 to 3/4 is not that far when you take your new swing to the course(see Moe Norman below), (7) you need to know what to do when you are playing poorly (return to the half swing until you figure it out) and (8) You need half swings on the golf course if you are within 50 yards of the green or are in the woods and have to hit out or need a half shot with a mid-iron or a hybrid.
Moe Norman's basic 3/4 (full) swing was not that far from the half-swing, as you can see in the graphic above.
If you think these half shots are not useful, the photo above is of Bryson hitting from 77 yards in the 2024 US Open (which he won, see the entire rounds here). Half-shots are essential for scoring and these are not fluffy, lazy swing shots. They are hit forcefully to put spin on the ball and you have too develop your golf muscles and practice to calibrate these shots.
I could go on, but most amateur, recreational golfers won't like this. They want to hit the ball as far as possible and skip the intermediate steps. That's why there are a lot of mediocre golfers.
Practicing half-shots is easy: get to the short-game area and start working. I'll go through Bryson's video above and make some comments.
