yeah, i was reading what you wrote, and it got me thinking about it. Where did u find the coan bench routine? all I find is an article from critical bench just re-written, like one with actual percentages and the assitance work you know?
i tried 5.3.1 rep maxes went up actually 1 rep max didnt..... for me my westside type split is this way.
Monday ME upper..
ME movement: coans bench routine weather its 2 x 10, or 2 x 1 thats ME movement...
weakness assistance movement- my weakness is my lockout 3/4ths the way up. so i do close grip floor press without flaring my elbows at all this is for 4 setts of 6-10 reps... this should be a heavy movement to help ur weakness.
Then shoulders- my frnt delts get enough work from bench so i do face pulls and lateral raises. 3 x 10-15 for each.
Tricep Endurance- 4 x 25 pulldowns this is to build up endurance so that ur triceps dont fatiuge quick focus on form. and dont go too heavy...
this is very similar to defrancos westside for skinny bastards 1 except i do no back movement and 2 shoulder movements.. i do 2 back movements on DE day because i can go heavier then... with this routine the key to successfor me is the weakness asssitance movement. which u should rotate every 2-3 weeks, and also pick it so its not stressing ur rotator cuffs since u will be doing full ROM bench press every week. so basically rotate the Weak assistance movemnt like a ME. but keepME as your bench press that coan suggests..
i dont do a upper body DE i do an assistance day which i do
C.G board Press 2 x 3 or 2 x 5 but rotated with other weaknesses.
D.B exentions seated 4 x 8-10 (or other moderate difficulty tricep lift)
2 back movements one heavy and basic such as rows another is a form of pulling such as pulldowns seated row etc.. both 3 x 8
(flyes and bicep work if u want dont go heavy on flyes tho)
since i lift raw and feel that i need to do the full ROM to do the actualy lift this has worked the best..this hits the tris hard without killing your rotator cuffs. and you still use the westside way of using different movements to help your weaknesses.
