I am splitting it Chins/KB Bottom Up Press, FatBarCurls/TriPress, DB Bench or pushups/Cable Rows, then I leave the fourth push pull for whatever I am feeling for fun on the friday(lot of times more chins because I am weak in the area). I keep it flexible though to stay engaged although the intensity and mental focus is still lower than the big 4 it still taxing.
Lot of time I superset the work too. Tend to throw in single leg work on Monday and Thursday when it calls for it. Have some imbalance I can feel that definitely benefit.
