Short stepping it a little in the jerk...
With the jerk, if you use the 1/4 squat as the main forcer (no pressing) and learn that the leg movement and feet separation in the split jerk is more a way to change levels and get under the bar rather a super press, like so
the jerks will come alot easier.
You'll see in these videos the main forcer causing the bar to rise in free air is solely from the 1/4 squat, and split jerk with both lifters is almost like a lunge under/drop under. if that makes sense
