Everyone's got an opinion on the "best" workout split.
Scroll through any fitness forum and you'll find people defending their preferred split like it's a religion.
But here's the thing.
The specific split you follow matters way less than whether it respects a few basic principles.
Principles that most lifters never think about.
This article ranks every major training split for hypertrophy, from the classic bro split to push/pull/legs to full body and beyond.
No dogma. Just science-backed reasoning and practical experience.

The Three Principles That Actually Make or Break Your Split
Before ranking anything, you need to understand the three variables that determine whether a split works for muscle growth.
That's it. Three things.
1. Adequate recovery between sessions for the same muscle.
If you train chest on Monday, your pecs need enough time to recover before you hit them again.
Train them too soon and you're working a muscle that hasn't fully repaired itself yet.
Research on muscle protein synthesis shows that the repair process is elevated for roughly 48 to 72 hours after a hard session, then returns to baseline.
2. Not too much recovery time.
The flip side is equally important.
If you're only training biceps once a week, you're leaving growth on the table.
Most muscles are ready to be stimulated again within two to three days.
Training them once every seven days means five or six days of sitting idle while that muscle could be growing.
3. Interference between sessions.
Heavy rowing on Tuesday followed by squats on Wednesday?
Your fatigued back and erectors become the limiting factor on leg day.
Push day (chest, shoulders, triceps) followed immediately by a shoulders-and-arms day?
That's redundant overlap that kills performance.
| Principle | What It Means | Common Mistake |
|---|---|---|
| Enough recovery | Target muscles need time to repair before the next session | Training the same muscle on consecutive days |
| Not too much rest | Don't let fully recovered muscles sit idle for days | Only hitting each muscle once per week |
| Minimal interference | Avoid fatiguing muscles needed in tomorrow's session | Heavy back work the day before squats |
Everything else about split design, like exercise selection, training volume, and exercise order, is independent of the split itself.
The split is just the schedule. Those three principles are the only things it needs to get right.
If your split nails recovery timing and avoids interference, you've already won 90% of the battle. Everything else is personal preference.
The Bro Split: Not Dead, Just Overrated
The classic bro split. Chest Monday, back Tuesday, shoulders Wednesday, legs Thursday, arms Friday.
Each muscle group gets hammered once a week with a ton of exercises and volume in a single session.
It's the split that built the Golden Era. And it still works for certain people.
Here's what it does well:
- Tons of exercise variety per muscle group, hitting your chest from every angle with seven different movements
- Simple to understand. Today is chest day. Period. No overthinking required
- Approachable for beginners who want clear structure
But the cons are significant.
You're cramming all your chest work into one session.
By set 15, you're running on fumes.
Your last few sets are basically junk volume because you started strong but now you're just going through the motions.
The scheduling problem is real too. Miss leg day? See you next Thursday. There's zero flexibility built in.
And then there's the frequency issue.
A meta-analysis on training frequency found that training muscle groups at least twice per week produced superior hypertrophy compared to once per week.
Your side delts can be trained practically every day.
Training them once a week? That's leaving a massive amount of potential growth untapped.
| Who You Are | Bro Split Rating |
|---|---|
| Average lifter | C to B tier |
| Female or smaller lifter | D tier |
| Pro bodybuilder (huge, very strong) | B tier |
| Beginner wanting simplicity | C tier |
The volume-equated research is clear: 10 sets on Monday versus 3 sets Monday, 3 sets Wednesday, 4 sets Friday produces roughly the same growth when total weekly volume is matched.
But if you can recover well enough to train more frequently, spreading that volume across three sessions means higher quality sets on every single one of them.
That's where the bro split falls apart for most people.
The bro split isn't terrible. But for most lifters, training each muscle only once a week means you're recovering for days with nothing to show for it.
Full Body Training: The Minimalist's Best Friend
Full body training means you're hitting some variation of every muscle group in every session, typically three to four days per week.
For the general population, this might be the most practical split that exists.
Why does this work?
It's perfect for minimal effective dose training.
If you've got two or three days a week and you just want to be fit, healthy, and progressively building muscle, full body two to four times a week is the way.
Smaller muscles absolutely thrive on this approach. Shoulders, biceps, calves... these recover fast.
They need stimulation three or four times a week to grow optimally.
Full body gives them exactly that.
It's also incredibly schedule-friendly.
- Miss a session? No big deal. You'll hit everything again in two days
- Traveling for a week? Three quick sessions still cover your whole body
- Busy season at work? Scale down to twice a week and maintain everything
Here's the catch.
When you're big and strong, full body stops working well.
Imagine trying to do justice to heavy squats, heavy bench, heavy rows, AND all your accessory work in one session.
The warm-up logistics alone are brutal.
You're warming up for squats, then warming up for bench, then warming up for rows, constantly switching between equipment and movement patterns.
And after a grueling set of heavy squats, everything that follows suffers.
Your back work is compromised. Your pressing is weaker. You're gassed.
| Full Body Pros | Full Body Cons |
|---|---|
| High frequency for all muscles | Hard to specialize or prioritize |
| Flexible scheduling | Sessions get very long when volume is high |
| Great for beginners and intermediates | Warm-up logistics between muscle groups |
| Minimal effective dose training | Not ideal for advanced, very strong lifters |
| Handles missed sessions well | Fatigue from one exercise hurts the next |
For the average person lifting three to four times a week? B+ tier.
For advanced lifters who are very strong and jacked? D tier.
You simply can't do justice to chest, back, AND legs in one session when each of those requires heavy compound work with extensive warm-ups.
Full body is perfect for the lifter who wants results without complexity. But the bigger and stronger you get, the harder it becomes to fit everything into one productive session.
Push/Pull/Legs: The Gold Standard for Hypertrophy
Push/pull/legs solves the two biggest problems in split design simultaneously.
It prevents doing too much in one session (the bro split problem).
And it prevents doing too little per muscle group per week (also the bro split problem).
It's the Goldilocks split.
Here's why it works so well.
The groupings are logical. Muscles that push train together. Muscles that pull train together. Legs get their own day.
Zero interference. Your back isn't pre-fatigued before leg day. Your triceps aren't shot before chest work. Everything flows.
And the scheduling flexibility is incredible.
You can run it asynchronously: push, pull, legs, push, pull, legs, rest... repeating forever.
Not recovered yet? Take an extra rest day. Need to miss two days? Pick up where you left off.
No rigid weekly structure required.
The One Tweak That Makes It S-Tier
Vanilla push/pull/legs has one weakness.
Side delts and biceps get trained once every three sessions. That's not enough for muscles that recover in 24 to 48 hours.
The fix is simple.
Add side delts and biceps to both your push AND pull days.
- Push day: chest, shoulders, triceps, side delts, biceps
- Pull day: back, rear delts, side delts, biceps
- Leg day: quads, hamstrings, glutes, calves
Now your side delts and biceps are getting hit four to five times per week instead of twice.
That one adjustment takes PPL from A tier to S tier.
| PPL Variation | Rating |
|---|---|
| Standard push/pull/legs | A tier |
| Modified (side delts + biceps on push AND pull) | S tier |
| Running it on a rigid 3-day schedule | B tier |
| Running it asynchronously (6-day rotation) | S tier |
Use our workout split generator to build a customized PPL template in seconds.
Push/pull/legs is hard to beat. Logical groupings, zero interference, flexible scheduling. Add side delts and biceps to every upper body day and it becomes the best split for most serious lifters.
Upper/Lower: The Reliable Workhorse
Upper/lower is exactly what it sounds like.
Upper body one day. Lower body the next. Usually four days a week: upper, lower, rest, upper, lower, rest, rest.
It's not flashy. Not exciting. But it gets the job done, every single time.
For anybody who wants to build muscle and get strong without overthinking their programming, upper/lower is rock solid.
You're training everything twice a week.
That's the sweet spot for most muscle groups according to the research.
The downside?
Less room for specialization and variety compared to PPL.
You've got two upper body days to fit in chest, back, shoulders, arms, and all your accessories.
It can feel cramped if you're trying to hit everything hard.
For the enthusiast who loves training variety and wants to really dial in specific muscle groups, upper/lower might feel limiting.
But for 90% of lifters? A tier. Maybe B+ if you need more flexibility.
Checklist for when upper/lower is your best bet:
- You can train four days per week consistently
- You want a simple, no-nonsense structure
- You don't need extreme specialization for lagging body parts
- You prefer training each muscle twice per week
- You value consistency over optimization
A modified push/pull/legs might be slightly better on paper, but upper/lower is still training everything twice a week, still allowing smart adjustments, and requires less planning.
Upper/lower is the split you can run for years without changing a thing. It's not the most exciting, but consistent twice-a-week frequency for every muscle is hard to argue with.
Modified Strength Programs: The Hypertrophy Trap
Starting Strength. StrongLifts 5x5. Greyskull LP.
These programs promise simplicity and strength gains, and they deliver on both.
But they're not hypertrophy programs. And pretending they are is where people go wrong.
Here's the problem.
These routines focus almost exclusively on the big compound lifts: squats, bench, deadlifts, overhead press, rows.
That's great for building a strength base.
But for maximizing muscle growth? You're completely neglecting:
- Side delts and rear delts
- Direct arm work (biceps and triceps isolation)
- Calves
- Any isolation work for lagging muscle groups
You can't build a complete, well-developed physique by only doing five exercises.
The "just squat and the rest will follow" mentality sounds appealing.
It's simple. It's dogmatic. And it's wrong for anyone whose primary goal is muscle growth.
You don't need barbell low bar squats or sets of three to build a foundation.
Any compound exercise that targets the musculature you want to develop, with a deep stretch, in the 5 to 15 rep range, will build just as much of a "base."
Research shows a clear dose-response relationship between training volume and hypertrophy, and these minimalist programs simply don't provide enough targeted volume for individual muscle groups.
| Program Type | Beginner Rating | Advanced Rating |
|---|---|---|
| Starting Strength / 5x5 | C tier | F tier |
| Modified strength + accessories | C tier | D tier |
| Hypertrophy-focused splits | A to S tier | A to S tier |
It's fine to start with one of these programs as a true beginner.
But eventually, your fatigue management catches up.
Eventually, you want to emphasize certain muscles over others.
And these programs simply don't have the framework for that.
Strength programs build strength. That's what they're for. But if hypertrophy is the goal, you need a split designed for muscle growth, not one that treats it as a side effect.
How to Choose the Right Split for Your Schedule and Goals
There's no universally "best" split.
The right one depends on three things: how many days you can train, how advanced you are, and whether you need to specialize.
| Days Available | Experience Level | Recommended Split |
|---|---|---|
| 2-3 days/week | Beginner | Full body |
| 3-4 days/week | Beginner to intermediate | Full body or upper/lower |
| 4 days/week | Intermediate | Upper/lower |
| 4-6 days/week | Intermediate to advanced | Push/pull/legs (modified) |
| 5-6 days/week | Advanced | Modified PPL with extra frequency for small muscles |
Stop thinking in terms of splits and start thinking in terms of principles.
Does your schedule give each muscle enough recovery time?
Are you avoiding unnecessary interference between sessions?
Are fast-recovering muscles like side delts and biceps getting enough weekly volume?
If you can answer yes to all three, your split is working.
The specific label on it doesn't matter.
Once you've picked your split, make sure you're progressing volume properly across each mesocycle and using a solid progressive overload strategy to keep driving adaptation.
Use our training volume calculator to figure out your weekly set targets and our progressive overload calculator to plan your loading.
The best split is the one that fits your schedule, matches your training age, and respects recovery. Pick one, adjust as needed, and stop overthinking it.
TL;DR
- Three things determine whether a split works: adequate recovery, not too much rest, and minimal interference between sessions
- Bro split (C tier): works but wastes recovery time and limits frequency for most people
- Full body (B+ tier): perfect for beginners and busy lifters, falls apart for very advanced trainees
- Push/pull/legs (A to S tier): the gold standard. Add side delts and biceps to every upper day for S tier
- Upper/lower (A tier): reliable, simple, trains everything twice a week
- Strength programs (C to D tier): build strength, not optimized for hypertrophy
- Principles matter more than the split name. Recovery timing, interference, and frequency are the real variables
