While we have the axe out, axe everything and keep just one combo of that style of Chest/Back SS'ing. Example might be the bench SS'ed with BB rows. Seeing as how PL69 is a fan of too many sets, he might play with the idea of reducing the amount of sets (and exercises). GVT (10X10's) comes to mind when doing the SS chest/back style of training. Using the suggested bench/BB row in the process. Or any other combo of chest/back movements you might want; like inclines/pulldowns, dips/chins, etc.. In any event, he might surprise himself with some impressive new muscle gains.
GVT can be done in a short period of training time as opposed to what PL69 has been doing. Ten sets vs 19 sets. Which will allow more time with his wife (or anyone's wife for that matter). Good Luck.
