Every 2 minutes, for 20 minutes (10 sets), of:
2-Position Snatch with Pauses
(stand with the barbell, descend to mid-thigh and pause for two seconds, then snatch from there, then reset to the hang, descend to 2″ below the knee, pause for two seconds, then snatch from there)

Start at roughly 70-75% of your 1-RM snatch, and build in load over the course the sets, never exceeding a load that you can perform at prescribed tempos and with perfect mechanics.
