Work up to 5x5 reps using 80-110% of 1RM Jerk.

Bend at the knees only just as you would for the jerk with a smooth and controlled tempo, and stand again with the same controlled tempo. This is not a quick, springy movement like the actual dip and drive of a jerk, but a controlled strength movement.
