idk, anyone that I have met that runs much I don't think I ever qualify as big, made more shapely then a sedentary person but not like what we are after.
my routine changes to some degree. I use a 9 workout rotation, 3 different weeks, everytime I hit the same thing again I have to increase by weight, reps or volume depending on whats going on.
recently I am in a perpetual state of just getting back into things but all the time off I actually use to my advantage to decondition my cns so that I am able to progress again by using essentially the same things.
I have had coaching and direction with weights and training since I was 13 for football. in college my head coach went pro as did a couple guys on my team and we had many serious juice heads that I learned form. a few years after that I higher DC so my background has largely been heavy intense lifting. I made great progress when I tried a volume scheme that I made up form an adaptation of a program from competitive athletes using 100s.
currently my split is typically:
Monday, chest/shoulder, secondary tri day
Tuesday, back, secondary bi day
Wednesday, off
Thursday, legs
Friday, bi/tri secondary chest shoulder
I structure things around the idea of 5 sets of 20 but it does vary a bit to ensure constant progression and progressive over load.
I typically pick 2 exercises per muscle group per day so 6 in total ( 3 different days per body part )but add in a little extra stuff as I progress.
the first work set is always the heaviest/hardest so I will use as much weight as possible for 20 reps, what happens next will depend on where I am, either just stating or progressing. if just starting it will be that heavy 20, then 10-15 same weight, if I get 15 the next would be 10 then I would drop weight so that I could get 20 but the last sets would have some type of modification that would increase time under tension.
to write out the whole thing would take quite a while, maybe if I have some free time, but that gives you a little idea.
