I'm as pretty much doing the same routine as you. Only more volume at 18 sets per day.
Crazy first year. Picked up 26KGs only muscle. Then 8Kgs the second year...then it tapered off with few and fewer gains. I know this normal, but if i'm gonna do it then i want above average results.
So this is my view/experience.
Training a single one or two muscle groups a day worked well for me at the beginning. I'd do five days per week. 2 days were only chest(18sets). 3 days were two other muscle groups per day (9sets each). Drop sets to fail, because I train alone.
So always 18 sets per day and five days per week.
I feel there are probably two reasons outside of the usual slower gains over time graph why i slowed down.
1) I never changed up my routine enough.
2) I now come to understand that around 40% of my time in the gym was wasted.
Everyone preaches changing up routine and I'm certain that there is a reason for that. Problem for me is home gym. I have a lot of stuff, but not enough to have numerous sets of pre-stacked weights ready to go.
Ideally, I'd do 6 different exercise per day...3 sets each. Instead, i was doing 3 exercise at 6 sets each.
Then i decided to cut on weight for six months so I downed the weight and upped the reps by double. Did that for six months and realised that it was not really working and i was also becoming lazy.
So started doing some reading.
As i understand it; 20 sets per week per muscle group is ideal.
Going beyond 5 sets on a muscle group in one session overshoots the peak of the returns graph.
This means that if one does between 15-20 total sets at 5 sets per muscle group per session, one gets more muscle groups done per day while shredding them the right amount.
It adds intensity because you are splitting the workout into 3 or 4 muscle groups and so you move from set to set tired but fresh in the muscle that you want to train, since it has had a 5 minute rest.
I change the exercises per muscle group once per week and also rotate in a new muscle group and drop out one of the others. I train to fail from set 1 and use drop sets on some of the more dangerous exercises.
Thats what i've been doing.
BUT...
I'd rather workout twice a day than take supplements. It just feels unnatural.
Protein - Want to hurl every time. Every single time.
Pre-workout - Enough caffeine to kill an Italian. No way raising one's heart rate artificially like that is good for you.
Creatine - There are a whole list of debated side effects. Just the fact that it's even debated makes me worry.
The rest are all fine in my view. Aspartic Acid and BCAAs vital to the cause.
The routine of taking them is a big part of why i dislike about supplements. Training without them is useless though.
My view is that a good supplement routine can disguise a poor workout routine until relatively high tiers.
I'd like to say that this was the core of my problem but in reality that would'e be a lie.
All i know is, the routine i have been doing lately has caused the most change that i've seen in a good while.
Perhaps it'll naturally stagnate but for now its making me feel jacked.
