Using push/pull method for training is very good...i usually do it at least once a year.
I break it down as say day one would be "horizontal push/ vertical pull"
for example -horiz push: bench press, incline db's, decline, push up etc
vertical pull: pull ups, chin ups, lat pulldown variations etc upright rows, front raises
Then day two would be "vertical push/horizontal pull.
vertical push: barbell shoulder press, dips, "arnolds", etc
horizontal pull: all variations of rows...db's, different machines/handles etc
If I'm looking for more of a circuit type workout...i will super set , or tri set. for example db bench press-pull ups-flys then rest/repeat 3x and move on to 2 or 3 other movements.
hope some of this helps.
