Heavy day!! The 2 push press should have you working hard to finish with those legs extended and continuing the press. No dropping under the barbell yet. Save that for the split jerk where you should be working on foot position when receiving the barbell and speed under the bar. The push press beforehand should force you to work on the speed with the split jerk.
Seated DB Press:
Both sets should be near but not too failure. Rest 3 min between each and adjust loading as needed.
50 banded ab May sit-ups
50 Superman or back extension
