What is Kinematic Sequence in Golf?

Kinematic sequence is the order in which the four big body segments fire during the downswing. In every elite golfer ever measured on a 3D motion-capture system, the sequence is the same: the pelvis accelerates first, reaches peak speed, and decelerates. Then the torso peaks. Then the lead arm. Then the club. Each segment slows down so it can transfer its speed into the next one — the same way a whip cracks.

Amateurs almost always run the sequence backward. They start the downswing with the arms or the upper body, and the hips never get to lead. The result is over-the-top, casting, early extension, or all three. The signature of a bad sequence is that the club reaches its peak speed before the wrist release happens — meaning all the energy got spent before it could be delivered to the ball.

You cannot fix a broken sequence by thinking about it during the swing — there's not enough time. The fix is to train the lower body to start the downswing with a small amount of pressure shift and rotation, while the upper body stays patient. Drills with split grips, step-throughs, and pump-pause routines all train the same thing: let the bottom move first.
