Donny Shankle wrote a good post about Push Press for Olympic lifters.
He emphasizes the importance of the eccentric portion of the lift.
Although the concentric portion of the push press is often thought of to be the most important, it is the eccentric portion which will help you more as a weightlifter during your jerk.
For weightlifters he recommends
Reps: 1-5
Sets: 5
Advanced: Off the blocks once you are moving very heavy weights.
Duration: 15 – 20 minutes
Placement in Training: To be done once a week and prioritized at the beginning of training for the weightlifter who struggles with their jerk.
