Lots of hip extension in this one so there is going to be some interference between movements here. Breaking things up from the start may be smart for some of us to meet the goal time domain but you shouldn’t have to do any more than 2 sets to accomplish the work when you are fresh. Push Press starts from the floor so some bigger sets may pay off since we can avoid picking up the barbell for other sets. Fight hard to keep this a push press and don’t drop under the barbell turning the movement into a push jerk. Change things up a bit and try keeping the weight but lower the reps to 15-12-9 if needed in order to meet the goal time.
