Walk into any gym or open any lifting forum and you'll encounter two training splits that dominate the conversation: push/pull/legs (PPL) and upper/lower. Both are legitimate, well-structured ways to organise your training. Both can produce solid results. The debate over which is "best" generates enormous amounts of noise online — but the honest answer is that it mostly comes down to your schedule and your consistency, not some physiological edge one split has over the other.
This guide breaks down how each split works, what a typical training week looks like, who each one suits, and how to make the decision without overthinking it.
How push/pull/legs works
Push/pull/legs divides your training by movement pattern. Push sessions train muscles involved in pushing — chest, shoulders, and triceps. Pull sessions cover the pulling muscles — back and biceps. Legs sessions handle quads, hamstrings, glutes, and calves. Each session has a clear, logical focus, and there's very little overlap between days.
A standard PPL week runs six sessions: Push, Pull, Legs, rest, then Push, Pull, Legs again. This means every muscle group is trained twice over the week, which is a reasonable frequency for intermediate to advanced lifters who can generate enough stimulus per session to make the split worthwhile.
Sample PPL week (6 days)
| Day | Session | Main focus |
|---|---|---|
| Monday | Push | Chest, shoulders, triceps |
| Tuesday | Pull | Back, biceps, rear delts |
| Wednesday | Legs | Quads, hamstrings, glutes, calves |
| Thursday | Rest | — |
| Friday | Push | Chest, shoulders, triceps |
| Saturday | Pull | Back, biceps, rear delts |
| Sunday | Legs | Quads, hamstrings, glutes, calves |
PPL: pros and cons
Pros: Sessions feel focused and manageable because you're not spreading yourself across the whole body. There's plenty of room for volume — you can include both compound and isolation work without sessions running long. If you enjoy going to the gym frequently, PPL fits naturally into a six-day routine.
Cons: Six sessions a week is a significant commitment. If life gets in the way and you miss a day, the structure breaks down quickly. At 4–5 sessions per week, PPL becomes awkward — one full cycle takes more than a week, so some muscle groups end up trained less frequently than they could be. PPL also tends to reward lifters who can push hard on isolation-heavy sessions, which takes time and experience to develop.
How upper/lower works
Upper/lower splits the body differently: upper body sessions train chest, back, shoulders, and arms together; lower body sessions handle legs and hips. The two session types alternate, and the split lends itself naturally to four training days per week — two upper, two lower — with rest days in between.
Because you're training the upper and lower body twice per week, frequency is built in. You don't need six sessions to hit everything twice; you just need four. That makes upper/lower one of the most efficient structures available for anyone training four days a week.
Sample upper/lower week (4 days)
| Day | Session | Main focus |
|---|---|---|
| Monday | Upper A | Horizontal push & pull (bench, rows) |
| Tuesday | Lower A | Squat-focused (quads, glutes) |
| Wednesday | Rest | — |
| Thursday | Upper B | Vertical push & pull (overhead press, pull-ups) |
| Friday | Lower B | Hinge-focused (Romanian deadlift, hamstrings) |
| Saturday | Rest | — |
| Sunday | Rest | — |
Upper/lower: pros and cons
Pros: Four days a week is sustainable for most people with full-time jobs, families, or other commitments. The structure is flexible — missing one session doesn't derail the week in the same way. Each muscle group gets trained twice, which is enough frequency to drive progress. Upper/lower also suits people who are still refining technique on the big compound lifts, since the twice-weekly practice reinforces movement patterns well.
Cons: Upper body sessions can run long if you try to cram in too much — chest, back, shoulders, and arms in one session requires discipline to programme well. At 5–6 days per week, you'd need to add a fifth day or run an A/B/A one week and B/A/B the next, which adds complexity.
How training days should drive your decision
The single clearest way to choose between these two splits is to look at how many days a week you can reliably train, not how many you'd like to train on an ideal week.
- 3 days a week: Neither PPL nor upper/lower is the ideal choice here. Full-body training gives better frequency at this frequency.
- 4 days a week: Upper/lower is the stronger option. Four days maps onto the split almost perfectly — two upper, two lower, with built-in rest days that allow proper recovery.
- 5 days a week: This is the trickiest scenario. You could run upper/lower with an added full-body or lagging muscle day, or try a modified PPL where one muscle group only gets hit once per cycle. Neither is as clean as the four- or six-day versions.
- 6 days a week: PPL fits naturally. You can complete a full push/pull/legs cycle twice in six days, hitting everything twice a week, and still take one rest day.
Frequency and recovery: what actually matters
The research on training frequency is fairly consistent: most muscle groups benefit from being trained at least twice a week, rather than once in a traditional "bro split" style. Both upper/lower and PPL (run at six days) achieve this, which is part of why they're both well regarded.
Recovery matters just as much as the split itself. Sessions that are too long, too frequent without adaptation, or loaded with junk volume can impair recovery and lead to stalled progress or injury. Whichever split you choose, keep sessions focused, track your lifts, and build volume gradually rather than trying to do everything at once.
Sleep and nutrition don't change based on which split you run. The basics — adequate protein, enough total calories, seven or more hours of sleep — apply equally to both. A well-recovered lifter on upper/lower will outperform a poorly recovered lifter on PPL every time.
Who each split actually suits
Upper/lower tends to suit: people with four consistent training days available; those who are still building their base of strength and technique; anyone who has had to rebuild consistency after a break; and lifters who prefer a bit more structure to their week with predictable rest days.
PPL tends to suit: more experienced lifters who can generate a strong training stimulus on focused muscle-group sessions; people who genuinely can commit to five or six sessions a week without that number slipping; and those who enjoy the detail of spending a whole session on one muscle group category.
- Upper/lower is the better default at 4 days a week — two upper, two lower, everything hit twice.
- PPL shines at 6 days a week, giving a clean push/pull/legs cycle twice over.
- At 3 days, neither is ideal — full-body training is the stronger choice.
- Both splits can drive good results; the difference is schedule fit, not magic.
The honest verdict
There is no universally superior split. The training forums would have you believe there's a clear winner, but the gap between a well-run upper/lower programme and a well-run PPL programme — for a given lifter on a given schedule — is small. What's not small is the gap between consistent training and inconsistent training.
Choose the split that matches the number of days you can actually get to the gym, week after week, not the number you can manage during a good fortnight. If upper/lower means you hit four solid sessions every week without fail, it will serve you better than a six-day PPL you can only maintain half the time.
Apply progressive overload, eat enough protein, recover well, and pick the structure you'll stick to. That's it. If you'd rather have someone build the structure for you — and adjust it as you go — that's exactly what online coaching is for.
