I have had VERY good results with my current press set/rep scheme:
warm up (max of 4 reps on these sets).
My warm up reps are usually as follows:
2 (last warm up set is -10% of your 2 rep max)
the work sets are 8 sets of 2 reps at your two rep max. make all the reps, bump up the weight next press day. If you cant make all the sets, shoot for doing single reps until you hit 14-16 reps.
I do this on mondays with (and before) my clean and jerks. Wednesday is squats and bench press. Friday is front squats and incline dumbell press.
I treat the bench press and incline db press as 'assistance' work for the press. My work sets for both of these exercises is 5 sets of 3 reps. and its ALWAYS progressive meaning I always bump up the weight, if i can.
Doing this program for several weeks you should not plateau but if you dont feel strong I would do 5x3 presses with no more than 80% of your 2 rep max.
Using this pressing scheme I have made great gains after about 3 months of plateaus.. Just today I hit a 10% pr from my last 1 rep max testing about a month ago.
If any of this is confusing, ask for clarification.. I'm a little tired and not writing carefully. But my friend and I both use this scheme and we're making gains all around.
