We all know the standard cookie-cutter advice given to natties: "Hit every muscle group twice a week, keep volume low-to-moderate, focus on progressive overload." While that’s fine for the average gymbro, the game changes entirely when you introduce an enhanced chemical profile.
The old-school 90s response was the High Concentrated Volume bro split (annihilating a muscle once a week with 25+ sets). The modern science-based response leans heavily toward high-frequency PPL or Upper/Lower variations.
But what actually yields the absolute best? Let's break down the most popular splits:
The old-school 90s response was the High Concentrated Volume bro split (annihilating a muscle once a week with 25+ sets). The modern science-based response leans heavily toward high-frequency PPL or Upper/Lower variations.
But what actually yields the absolute best? Let's break down the most popular splits:
1. The Modern Push/Pull/Legs (PPL) – 6-Day Rotation
- The Blueprint: Push / Pull / Legs / Rest / Repeat (or a straight 6 days on, 1 day off).
- The Logic: Keeps frequency high. You capitalise on constant protein synthesis by hitting everything every 4 to 5 days.
2. The Arnold Split (Chest/Back, Shoulders/Arms, Legs)
- The Blueprint: Chest & Back / Shoulders & Arms / Legs / Repeat.
- The Logic: Massive, skin-splitting pumps due to agonist/antagonist training. It allows you to dedicate an entire day to arms and shoulders, which often get left with the scraps at the end of a PPL session.
3. The Upper/Lower Split (Torso/Limbs)
- The Blueprint: Torso (Chest/Back/Shoulders) / Limbs (Biceps/Triceps/Legs) / Rest.
- The Logic: Incredible for arm and leg specialization. It balances out the recovery demands beautifully by separating the heavy trunk movements from the peripheral limbs.
4. The High-Intensity, Low-Frequency Dorian's Style
- The Blueprint: Lower frequency (training 3–4 days a week), extreme low volume (1–2 working sets to absolute failure), max rest (sometimes even 4-5 minutes).
- The Logic: Forces massive mechanical tension and lets the chemistry handle the rest during deep recovery windows.
Which is your favourite?
The "best" split is the one you can progress on without your joints screaming, but everyone's unique biomechanics and recovery thresholds dictate a different path.- How do you structure your microcycle? Are you a 7-day calendar planner, or do you let your split rotate freely based on how you feel?
- How do you adjust volume vs. frequency? When you are pushing, do you scale up the volume per session, or do you increase the frequency of the stimulus?
- What does your current split look like right now?
Split (6 days on 1 off):
Day 1 — Chest & Back
Day 2 — Shoulders & Arms
Day 3 — Legs (Quads focus)
Day 4 — Chest & Back
Day 5 — Shoulders & Arms
Day 6 — Legs (Hams focus)
Day 7 — Cardio (30 mins x 2 machines)
Principles I follow:
Hypertrophy-first: compounds 4 to 8 reps for tension, accessories 12 to 15 for volume, finishers 15 to 25 for abs and calves usually.
Weekly volume target: 20 to 25 sets per muscle, adjust by recovery and feedback.
Prioritize mind-muscle, short rests (60 to 90s) on accessories and finishers, longer on heavy sets.
Manage joints with mobility (I hate doing it but i do 3 mins pre lift)
Observed effects with this split:
-Faster recovery between sessions, permitting slightly higher weekly volume.
-Enhanced muscle fullness and quicker strength increases.
-Still required programmed deloads and joint-management to avoid overuse.
Results: clearer striations and greater muscle definition in chest and hamstrings, really improved training frequency tolerance.

Reactions: learthzzI usually have to modify the pre-made programs to work around my injuries. There are some great exercises that I can't do because they really hurt my joints, especially knees, so I have to replace them with less effective ones while building up knee strength. I can painlessly do some things now that always used to hurt, but I still have to avoid others.
Then cardio, of course, I try to cram in a short session after my lifting, and have a day or two per week for a longer one. This is all I can fit into my days now.

Reactions: learthzz and Lord Trenner
Reactions: learthzzPersonally, I treat them with high density at the end of my sessions. For abs, I only train them on chest and back or shoulders and arms days, doing just one single exercise for five sets with very short rest periods to chase that burn. For calves, I keep them strictly on leg days but alternate the stimulus. On my first leg day, I run three heavy, high-intensity sets with standard recovery. On the following leg day, I switch to three lighter sets with high repetitions and minimal rest to force as much blood into the muscle as possible.
I would love to hear how the rest of you structure this. Do you just throw them in at the end of a workout as I do, or do you prioritize them at the very beginning when you are fresh? Let me know if you believe calves require heavy progressive overload or high-rep work, and whether you prefer weighted movements or high-density bodyweight training for abs.

Reactions: learthzzA-High Volume
B-High Intensity
Starting with Chest/Biceps and a little bit of quads on Mondays both A
Just pushing my Weights to the absolute limits because I don’t wanna look jacked but be weak.
And it really works for me I pushed my bench PR from 165KG to 190KG.
Tuesdays rest
Wednesday
Back/Triceps/Hamstrings
It’s a B day so I just focus on the feeling and how the weights move and try to get as many sets and reps out of it
Thursday is Arms with more focus on my Weakspots so a B Day
I just focus on how my weight moves and how the muscle feels.
And I mix in a little bit of calves.
Fridays is Chest B/Back A/Shoulders B
For the Chest more focus on the muscle and the feeling I get and push my sets to the absolute limit
For Back I just push the weights to my limit and try to get a decent pump mostly rowing and excercises I do without any machines like Bent over rows.
Shoulders is more focused and try to push to limit with moderate weights.
Saturday is Legs A
It’s a A day because while I’m training other muscle groups as you can see above I just do simple exercises with moderate weights just to get a feeling and a pump.
On Leg day I usually just push myself to my limits heavy lifts on everything

Reactions: Lord TrennerYour undulating A/B setup is a great way to balance dense strength work with pure hypertrophy, and spreading out the leg volume is a great tactical move for recovery.
Since you have such a great mind-muscle connection on those feeling-focused B days, you should definitely try dropping your rest times down to 60 or 90 seconds on your finishing exercises. Keeping the rest that short creates metabolic stress and an insane pump (trust me) which would fit perfectly into your weaker-point arm days (they grow with more volume IMO) and chest isolation work.
Keep crushing it, that 200KG bench will be a cake walk for sure
