Push/Pull/Legs vs Upper/Lower: Which Split Is Better?

For most lifters, a 4-day upper/lower split and a 6-day push/pull/legs split build muscle about equally well, because both train every muscle roughly twice a week — the frequency research links to the most growth. The real tiebreaker is not the name of the split but how many days a week you can train hard and recover: pick upper/lower if that number is 3-4, and push/pull/legs if you can genuinely commit to 5-6.

What's the difference between push/pull/legs and upper/lower?

The two splits sort the same exercises in different ways. Upper/lower sorts by region: one day of pressing and rows for the upper body, another day of squats and hinges for the lower body. Push/pull/legs sorts by movement: pushing muscles together, pulling muscles together, and legs on their own day.

Because each split bundles the work differently, they need a different number of days to cover the whole body the recommended twice a week. A typical week looks like this:

• Upper/Lower (4 days): Upper A, Lower A, rest, Upper B, Lower B — each muscle trained twice.
• Push/Pull/Legs (6 days): Push, Pull, Legs, then repeat — each muscle trained twice.
• Push/Pull/Legs (3 days): Push, Pull, Legs once each — each muscle trained only once.

Is push/pull/legs or upper/lower better for muscle growth?

Neither, on its own. When you match total weekly volume, the two splits produce very similar growth, so the deciding factors are frequency and how much hard work you can recover from. A 2016 meta-analysis found that training a muscle twice a week beats once a week when volume is held equal — and both a 4-day upper/lower and a 6-day PPL clear that twice-a-week bar.

Where PPL can pull ahead is total volume. Six training days simply give you more room to accumulate the 10-20 hard sets per muscle per week that drive hypertrophy. But that edge is only real if you recover from the extra sessions and actually attend them — volume you skip, or junk sets done deep into a sixth straight day, build nothing.

How many days a week does each split need?

This is the question that should come first, because it decides the split for you. Match the routine to the days you can realistically train every week, not your best week:

1. 3 days: a full-body routine trains each muscle three times and beats a 3-day PPL, which hits each muscle only once.
2. 4 days: upper/lower is the sweet spot — two upper, two lower, every muscle twice.
3. 5 days: a push/pull/legs/upper/lower (PPLUL) hybrid, or upper/lower plus a weak-point day.
4. 6 days: full push/pull/legs — each muscle hit twice with the highest total volume.

Which split is better for beginners?

Upper/lower, in almost every case. Four days a week is easier to sustain than six, leaves more recovery between sessions, and asks you to learn fewer exercises at once. Beginners also grow on less volume than advanced lifters, so the extra sets a 6-day PPL allows are wasted before you can use them.

Start with a handful of big lifts, train each muscle twice a week, and add weight or reps as you go. Our beginner training hub walks through how to put a first program together without overcomplicating it.

Is PPL or upper/lower better for strength?

Upper/lower has a slight edge for strength. Pressing and squatting twice a week on relatively fresh legs and shoulders means more frequent practice of the heavy lifts, and the lower per-session fatigue lets you train those lifts harder. PPL leans more toward bodybuilding, with its movement grouping and heavier dose of isolation work.

That said, the split matters less than the loading. Either one builds strength if you apply progressive overload and add a little to the bar over time — the split just decides how the practice is spaced across the week.

Can you combine the two into a PPL upper/lower hybrid?

Yes — the push/pull/legs/upper/lower (PPLUL) hybrid is a popular 5-day middle ground: Push, Pull, Legs, Upper, Lower. It still trains everything about twice a week, but it slots into five days instead of six, which makes it easier to recover from and adhere to than a full PPL while carrying more volume than a 4-day upper/lower.

It is a sensible step up once a 4-day upper/lower stops being enough stimulus and you want a fifth day without committing to six. There is nothing magic about it — it is just another way to land each muscle on the twice-a-week target.

How do you choose between push/pull/legs and upper/lower?

Work through it in order — days first, split second:

1. Count the days you can train hard every week for months, not the days you managed in your best week.
2. If that number is 3-4, run upper/lower (or full-body at three). If it is 5-6 and you recover well, run push/pull/legs.
3. Confirm the layout trains each muscle twice a week and lands it in the 10-20 hard-set range.
4. Choose lifts you can progress on, then add weight or reps each week and write it down.
5. Give it 8-12 weeks before you judge it. Program-hopping, not the split, is what stalls most lifters.

Whichever you pick, the work after you choose is what moves the needle. If you have changed splits before and still stalled, our breakdown of why you might not be getting stronger covers the usual culprits, and the hypertrophy training hub goes deeper on volume and exercise selection.
