Wow, that is some massive volume. I would say that if your working out like that once is certainly pleanty!! Have you tried it the other way? ---> splitting workload bwtween 2 days? If so, hoow did/didn't this work out for you. Reps for detailed post.
yes i used to do a twice a week split in the first year of college up to about 1.5 years ago( now in my 4th year of college). One day would be a heavier day with light leg work. The other would be a lighter chest day with heavy leg work. I would do this for 3-6 months, then go to 2 FULL chest days a week, with legs also being 2 days a week, and i would do that for about 3-6 months and change again. In all that time i did make gains, esp while on cycle of course, but it was mostly strength and i wasnt really seeing the "mass" difference i was really expecting. Also, ive had a big chest since highschool b/c like a few others on here, i deposit more fat in the lower chest which makes me look as if i can do a 500lb press, lol ( Ive never been fat,then i was tall, skinny, wit a abnormally large lower chest) LOL. So one of my goals since getting into college was to also shape up my chest, and make it thick, and not "wierd" looking like it was in HS.
A reg chest workout at this time would look like:
flat bench: 1x12, 1x10, 1x8, 1x6, 1x4
incline bench: same set/rep #
flat flyes: 1x10, 1x10, 1x failure set
incline flyes; same set/rep #
3 sets of weighted dips
then leg routine:--->
* triceps workout if i had time (extensions or close grip)
Thats what i would usually do one day for a twice a week split, something like that, then the 2nd day, i would do maybe 3-4 set of dumbell work instead of bb presses and 4 sets on the pecdeck machine, and then with the heavier leg routine.
The difference between now and then is i am getting strength gains AND notice visible mass gains, so i think ive found the right base for my routine. Also my view on flyes is the same as squats/leg presses: go DEEP as hell!!!! Plus i have heard that guys with longer arms are more acceptable to results with flyes, i dont know how much evidence there is to support this, but the added volume of flyes has surely made a difference( in terms of shaping). Also in terms of my ego,... i threw it out years ago, so b/c of that my form now is near perfection on presses and flyes,.... slow and deep. i think that is also a key. hope this helps ya bro
