Upper/Lower vs Push/Pull/Legs: Which Split Should You Run?
Run either one at the right number of days and each muscle gets trained twice a week, so muscle growth comes out about even. The real difference is the calendar: how many days you can count on, how long each session runs, and what happens to the week when one day goes missing. This page is the head-to-head. Both programs are written out in full in our workout splits and programs section, and this is the page to read when you are stuck between the two.
| Your week | Run this | Why |
|---|---|---|
| 4 days, desk job, about 60 minutes a session | Upper / lower | Each muscle twice a week, three rest days to absorb a bad week |
| 6 days, a year or more of lifting, 7+ hours of sleep | Push / pull / legs, twice through | Same twice-a-week frequency; push and pull days run 30–45 minutes, so there is room for more sets |
| Glute and leg focus, 4–5 days | Upper / lower, both lower days built around the hips | Two to three lower sessions a week; push/pull/legs on 4–5 days gives legs fewer than two |
| 5 days | Upper / lower + one full-body day | Push/pull/legs does not divide into five without rotating |
| Only 3 days | Neither in its usual form: full body or upper / lower / full | Push/pull/legs on 3 days trains each muscle once a week |
| Schedule changes week to week | Upper / lower, run in order whenever you can train | Two session types are easier to keep in order than three |
The two splits across a week
Upper/lower divides the body in two: one session for chest, back, shoulders and arms, one for quads, hamstrings, glutes and calves. Push/pull/legs divides it in three: chest, shoulders and triceps; back, rear delts and biceps; then legs. That one difference sets everything else on this page.
| Split | Mon | Tue | Wed | Thu | Fri | Sat | Sun |
|---|---|---|---|---|---|---|---|
| Upper / lower, 4 days | Upper | Lower | — | Upper | Lower | — | — |
| Push / pull / legs, 6 days | Push | Pull | Legs | Push | Pull | Legs | — |
| Push / pull / legs, 3 days | Push | — | Pull | — | Legs | — | — |
In both full versions, the same session comes back 72 to 96 hours later: upper on Monday and Thursday, push on Monday and Thursday. Recovery time per muscle is the same. What differs is how many days you are in the gym, and how much work each visit has to hold. The day-by-day exercises live on the program pages: the 4-day upper/lower program and the push/pull/legs program in 3- and 6-day versions.
Frequency: how often each muscle gets trained
The 2016 Schoenfeld frequency meta-analysis found that training a muscle twice a week built more than once a week. The 2019 follow-up found that once weekly sets are matched, frequency itself matters little. Put together, the practical case for twice a week is that it splits a muscle's weekly sets across two sessions, so you are not trying to do 10 to 12 hard chest sets in one workout where the last few are done tired and add little. So the question for each split is simple: at the number of days you have, does it reach two?
| Days a week | Upper / lower | Push / pull / legs |
|---|---|---|
| 3 | Upper twice, lower once (then swap next week): 1.5× average | 1× |
| 4 | 2× | Rotating: each session 4 times every 3 weeks, about 1.3× |
| 5 | Rotating: 2–3× (or add a full-body day: 2–3×) | Rotating: each session 5 times every 3 weeks, about 1.7× |
| 6 | 3× | 2× |
Read it this way. Upper/lower reaches twice a week at four days. Push/pull/legs needs six. At four or five days, push/pull/legs falls between once and twice, and the sessions move around the calendar every week, so Monday is push one week and legs the next. Plenty of people run it that way, but it is harder to keep straight, and at four days upper/lower reaches twice a week with no rotation at all.
Volume: where the weekly sets fit
Muscle growth follows weekly hard sets more than the split. Most intermediates do well on roughly 10 to 20 sets per muscle per week; how many sets per muscle covers what counts as a hard set and where to start. The split decides how those sets are packed into sessions, and that is where the two pull apart.
A worked example. Take a mid-range intermediate week: chest 10 sets, back 12, side delts 8, biceps 6, triceps 6, quads 12, hamstrings 8, glutes 6, calves 6. That is 42 upper-body sets and 32 lower-body sets, 74 in all.
| Session | Upper / lower, 4 days | Push / pull / legs, 6 days |
|---|---|---|
| Upper or push | 21 sets | 12 sets (chest 5, side delts 4, triceps 3) |
| Pull | — | 9 sets (back 6, biceps 3) |
| Lower or legs | 16 sets | 16 sets |
| Rough session length | 55–65 min upper, 50–60 min lower | 30–45 min push and pull, 50–60 min legs |
| Gym visits a week | 4 | 6 |
Session length assumes about 2.5 minutes per working set including rest, plus 10 minutes of warm-up. Two things stand out. First, upper/lower crowds the upper day: 21 sets of chest, back, shoulders and arms is the most any session in either split has to carry. Second, push/pull/legs has slack: the push and pull sessions are short enough to add 3–4 sets each without passing an hour.
That slack is the honest case for push/pull/legs. Raise chest to 14 sets and back to 16, and the upper/lower upper day grows to 25 sets, around 70–75 minutes. On push/pull/legs the same increase adds 2 sets to each push day and 2 to each pull day, and neither session passes 50 minutes. If your volume needs are still in the middle of the range, upper/lower holds them in fewer trips.
Recovery: what each split asks of you
Per muscle, the two are close: 72 to 96 hours between matching sessions in both standard versions. The difference is everything around the muscles.
- Rest days. Upper/lower on four days leaves three. Push/pull/legs on six leaves one. Sleep, work stress, a long commute and any cardio all draw from the same recovery, and one rest day leaves no room for a bad week.
- Lower back. On push/pull/legs, a heavy barbell row or deadlift on pull day is followed the next day by squats or Romanian deadlifts on legs day. Fix: keep the heaviest hinge on legs day and use chest-supported or cable rows on pull day. On the Monday, Tuesday, Thursday, Friday upper/lower week, both lower days follow an upper day, so make Thursday's rows chest-supported and put the heavy hinge on Friday; the weekend then gives your lower back two days before Monday.
- Legs. On the 6-day push/pull/legs week, Saturday's legs day is the sixth training day in a row, so it is the session most likely to be cut short. If that keeps happening, move your hardest leg exercises to Wednesday's legs day.
Signs that six days is more than you are recovering from: a lift going down two sessions running, sleep getting worse, or dreading legs day every week. The fix is not always to switch. Try dropping one set per exercise for a week, or take a deload week, and if it keeps coming back, go to upper/lower.
Missed days and schedule flexibility
This is where most people actually decide, usually after the fact. A plan you complete three weeks out of four is a different plan from the one on paper.
| If this happens | Upper / lower, 4 days | Push / pull / legs, 6 days |
|---|---|---|
| You miss one session | Move it to the next rest day. Three rest days means there is almost always one free | No free day to move it to. Train it tomorrow and push the whole order back a day |
| Share of the week lost | One quarter. That half of the body still trains once | One sixth. That group still trains once |
| You miss two sessions | Do one upper and one lower that week; still a full-body week | Two groups drop to once; run the order forward, the week becomes eight or nine days |
| Travel for 3 days | Usually costs one or two sessions; move one to a rest day and the week stays recognizable | Costs two or three sessions; continue the order when you are back |
| Week where only 3 days happen | Upper, lower, upper. Next week starts with lower | Push, pull, legs once each: every muscle once that week |
The rule that keeps either split working: never skip a session in the order, and never stack two sessions into one day. If you missed lower on Tuesday and Wednesday is gone too, Thursday is lower, not the upper the calendar says. The order is what keeps one area from going ten days untrained while another trains three times.
The 3-day version of push/pull/legs is the most fragile: miss legs once and your legs get nothing that week. If three days is your realistic number, the 3-day workout split guide compares sturdier options.
The verdict by situation
Four days a week and a desk job
Upper/lower. Monday, Tuesday, Thursday, Friday, about an hour each. Sitting all day does not change which split builds muscle, but it usually comes with long days, a commute and evenings that get taken. Three rest days absorb that; one does not. If a session goes, move it to Wednesday or Saturday and the week is still complete. Lead each lower day with a squat or hinge while you are fresh, because lower days after work are the ones that get rushed.
Six days a week
Push/pull/legs, twice through, if all of these are true: you have lifted consistently for a year or more, you sleep seven hours most nights, and your upper/lower sessions now run long. Keep push and pull days near 45 minutes so the week stays manageable. If you can train six days but no session can run past about 45 minutes, upper/lower three times each spreads the same 74 sets more evenly: about 14 sets per upper day and 11 per lower day, against 16 on a push/pull/legs leg day.
Women who want more glute and leg work
Upper/lower, with both lower days built around the hips: one squat-led day and one hinge-led day, with a hip thrust or glute bridge on both and single-leg work on at least one. That gives glutes direct work twice a week without losing the two upper days. With five days, run lower, upper, lower, upper, lower: three lower sessions a week. Push/pull/legs gives legs one day in three, so at four or five days legs get fewer than two sessions a week; it only reaches two at six. Growth itself works the same way it does for anyone; how women build muscle covers the food and the timeline.
If none of these fits, the workout split decision guide covers every day count from two to six.
How to switch from one to the other
Keep your exercises and your current weights. Only the grouping changes, so week one of the new split starts from last week's numbers.
| Upper / lower exercise | Goes to |
|---|---|
| Bench press, incline press, overhead press, lateral raise, triceps work | Push |
| Rows, pulldowns or pull-ups, face pulls, curls | Pull |
| Squat, Romanian deadlift, hip thrust, leg curl, split squat, calves | Legs |
Going from upper/lower to push/pull/legs, each upper session splits in two, so you have room for 2–4 extra sets per session. Add them over a few weeks, not all in week one. Going the other way, merge push and pull into one upper day and trim each exercise by a set so the session still fits an hour. Either way, give the new split at least three months before judging it.
Mistakes people make choosing between them
- Choosing six days in a good week. The plan has to survive the bad weeks. Fix: run four days for two months without a miss before adding two more.
- Treating a missed day as a reset. Starting the week over on Monday means the session you missed never happens. Fix: continue in order.
- Switching because progress stalled. A stall is usually a progression or recovery problem. Fix: check your log against the rules of progressive overload, and check your sleep, before changing the split.
Questions people ask
Is upper/lower better than push/pull/legs?
Not by itself. Few studies compare the two splits directly, but the frequency research shows little difference in growth when weekly sets are matched and each muscle is trained twice. Upper/lower fits four days better; push/pull/legs fits six better.
Which is better for strength?
Upper/lower is the more common choice for strength because each main lift can be trained twice a week, one heavy session and one lighter one, in only four days. Push/pull/legs at six days gives the same lift frequency.
Can I do push/pull/legs 4 days a week?
You can, by rotating, but each muscle averages about 1.3 sessions a week and the calendar shifts every week. Upper/lower is the better 4-day split.
Is push/pull/legs 3 days a week enough?
It trains each muscle once a week. That builds muscle, but every weekly set for a muscle has to fit in one session, which caps how much productive work you can do. A full-body or upper/lower/full 3-day week spreads the sets and usually works better.
Is upper/lower good for beginners?
After the first few months, yes. Before that, three full-body days give more practice on each lift. Upper/lower is the usual second step.
Which one burns more fat?
Neither. Fat loss is decided mostly by how much you eat. The lifting helps you keep muscle while you eat a modest deficit, and either split does that.
Where these numbers come from
Twice a week beating once a week comes from Schoenfeld, Ogborn and Krieger, Effects of Resistance Training Frequency on Measures of Muscle Hypertrophy (Sports Medicine, 2016). Frequency mattering little once weekly sets are matched comes from Schoenfeld, Grgic and Krieger, How many times per week should a muscle be trained to maximize muscle hypertrophy? (Journal of Sports Sciences, 2019), and for strength from Grgic and colleagues, Effect of Resistance Training Frequency on Gains in Muscular Strength (Sports Medicine, 2018).
The link between weekly sets and growth comes from Schoenfeld and colleagues, Dose-response relationship between weekly resistance training volume and increases in muscle mass (Journal of Sports Sciences, 2017). Days per week by training age follow the American College of Sports Medicine position stand Progression Models in Resistance Training for Healthy Adults (2009). Session lengths on this page are our own arithmetic from the set counts shown, not study figures.
