Push Pull Legs and Upper/Lower are the two splits that serious natural lifters actually argue about. Full body is for beginners, the bro split is for people who like it, and everyone past their first year lands on one of these two. So which one?
The honest answer is that they produce almost identical results when run properly, and the whole decision comes down to one number: how many days a week you can train, every week, without fail. This article puts the two head-to-head on the things that genuinely differ, shows you a sample week for each, explains the 4-day trap that quietly ruins most PPL programs, and covers the hybrid that lets you stop choosing.
If you want the wider comparison including full body and bro splits, our guide to the best workout split for muscle growth covers all four. This one is just the two finalists.
The Short Answer
- You can train 4 days a week: Upper/Lower. It is not close.
- You can train 6 days a week and recover from it: PPL. Slightly more focused sessions, same growth.
- You can train 5 days: The PPLUL hybrid, which is Upper/Lower with one extra push-pull-legs cycle bolted on.
- You can only train 3 days: Neither. Full body wins at 3 days, and PPL once a week is a bro split with a better name.
Everything below is the reasoning.
What Each Split Actually Is
Upper/Lower
Four sessions a week, two upper-body days and two lower-body days, usually with a rest day after each pair.
| Day | Session | |-----|---------| | Monday | Upper A: bench press, row, overhead press, pull-ups, arms | | Tuesday | Lower A: squat, Romanian deadlift, leg press, calves | | Wednesday | Rest | | Thursday | Upper B: incline press, chest-supported row, lateral raises, arms | | Friday | Lower B: deadlift, front squat or hack squat, leg curl, calves | | Weekend | Rest |
Every muscle gets trained twice a week. Upper days are long because chest, back, shoulders, and arms all share them; lower days are shorter and heavier.
Push Pull Legs
Six sessions a week, three movement-pattern days run twice.
| Day | Session | |-----|---------| | Monday | Push: bench press, overhead press, incline dumbbell press, lateral raises, triceps | | Tuesday | Pull: deadlift or row, pull-ups, chest-supported row, rear delts, biceps | | Wednesday | Legs: squat, Romanian deadlift, leg press, leg curl, calves | | Thursday | Push (second variant) | | Friday | Pull (second variant) | | Saturday | Legs (second variant) | | Sunday | Rest |
Every muscle is also trained twice a week, but each session is narrower: a push day only has to cover chest, shoulders, and triceps, so the volume per muscle per session can be higher without the workout running past 90 minutes.
Frequency and Volume: The Numbers That Decide It
Two research findings settle most of the argument before it starts.
Weekly volume drives growth. Around 10 to 20 hard working sets per muscle group per week is the range that keeps showing up in hypertrophy research. Our sets and reps guide covers where in that range to sit.
Twice-weekly frequency beats once, at the same volume. Training a muscle two times a week produces more growth than once a week with the volume matched; going from two to three adds little for most lifters.
Now look at the two splits through that lens. Run as written, both give every muscle a frequency of two. Both let you fit 10 to 20 weekly sets per muscle. On the two variables that matter most, they are tied. What differs is everything downstream of the day count: session length, how the volume is packaged, how much recovery each week demands, and what happens when life removes a training day.
Head-to-Head Comparison
| | Upper/Lower | Push Pull Legs | |---|---|---| | Days per week | 4 | 6 | | Frequency per muscle | 2x | 2x | | Session length | 60 to 90 min, upper days run long | 45 to 75 min, focused | | Sets per muscle per session | 4 to 6 | 6 to 10 | | Rest days | 3 | 1 | | Recovery demand | Moderate | High | | Missed-day damage | Low: the pair still gets hit | High: a missed day drops a muscle to 1x | | Weak-point flexibility | Easy: add a fifth day | Easy: bias one of the six sessions | | Best for | Intermediates, 4 reliable days | Intermediate to advanced, 6 days, strong recovery |
Where Upper/Lower Wins
It survives real life. Four days leaves three rest days, and if one session slips, you can shift it without breaking the frequency. Miss a day on a 6-day PPL and one movement pattern drops to once a week; miss two and the split has quietly turned into something else.
It is the most research-backed default. Twice-weekly frequency, moderate volume per session, plenty of recovery. For natural lifters in their second to fifth year, Upper/Lower is the split most likely to produce steady progress with the fewest ways to mess it up.
It plays well with strength goals. Lower A heavy squat, Lower B heavy deadlift, Upper A heavy bench, Upper B heavy overhead press: the four big lifts each get a dedicated heavy slot with fresh legs and full rest days around them. PPL can do this too, but the deadlift-on-pull-day-after-legs problem is real.
Fewer sessions, same growth. If the two splits build the same muscle, the one that takes four trips to the gym instead of six is the better deal for most people.
Where PPL Wins
Sessions are cleaner. Push day is chest, shoulders, triceps, and every exercise overlaps helpfully. There is no 90-minute upper day where arms get whatever energy is left after chest and back.
More volume per muscle per session, without the marathon. If you are past the intermediate stage and need 16 to 20 weekly sets for a lagging chest, fitting 8 to 10 of them into a push day is easy. Fitting them into an upper day that also has to serve back, shoulders, and arms is not.
It is easier to bias. Want more shoulder work? Add it to both push days. Want a back specialization? Both pull days. On Upper/Lower every addition competes for space with three other muscle groups.
Routine. Six days a week, same time, same pattern, is its own kind of consistency. Some lifters are better at showing up daily than at showing up four specific days.
The 4-Day PPL Trap
This is the single most common split mistake, and it is worth its own section because so many people are making it right now.
PPL only delivers twice-weekly frequency at six days. Run it on four days as a rotating cycle (push, pull, legs, push one week; pull, legs, push, pull the next) and each muscle averages 1.33 sessions a week. Run it on three days and it is a bro split with three bigger boxes: every muscle once a week, which is exactly the frequency the research says is inferior.
The uncomfortable conclusion: at 3 or 4 days a week, Upper/Lower beats PPL every time. If you love the push-pull-legs structure but only have four days, you are better off running Upper/Lower and organizing each upper day as push-then-pull within the session. You keep the feel of PPL and the frequency of Upper/Lower.
How many days you can actually commit to, every week, for six months, is the real question, and our guide on how many days a week you should work out is the honest way to answer it.
The Hybrid: PPLUL and Upper/Lower/PPL
If you have five days, or six days but not the recovery for six hard ones, you do not have to choose.
PPLUL (5 days): Push, Pull, Legs, Upper, Lower. Every muscle gets hit twice: once in a focused PPL session and once in a broader Upper/Lower session. Two rest days. This is arguably the best 5-day split there is, and it fixes the 4-day PPL trap by adding the fifth day as an Upper/Lower pair rather than a fourth PPL day.
Upper/Lower/PPL (5 days): Same idea in the other order. Some people prefer the heavy Upper/Lower pair early in the week when they are freshest.
PPL/Upper/Lower/Rest (6 days, lighter): For lifters who want six days but find the second PPL cycle too much: run PPL, then Upper/Lower, then rest. Frequency stays at two, total volume is a little lower than full PPL, and recovery is easier.
Sample PPLUL week:
| Day | Session | |-----|---------| | Monday | Push | | Tuesday | Pull | | Wednesday | Legs | | Thursday | Rest | | Friday | Upper | | Saturday | Lower | | Sunday | Rest |
How to Choose in 60 Seconds
Answer three questions honestly.
How many days can I train every week, including bad weeks? Three: full body. Four: Upper/Lower. Five: PPLUL. Six: PPL.
How is my recovery? Sleeping under seven hours, eating too little protein, or carrying a high-stress job? Drop one day from whatever the first answer gave you. As our sleep and muscle recovery guide makes clear, recovery is not a bonus on top of training; it is the mechanism.
Do I have a lagging muscle group? If yes, PPL or PPLUL makes it easier to add volume where it is needed. If your development is balanced, Upper/Lower's simplicity is the advantage.
Then run the choice for at least 12 weeks. Switching splits every month because a new video convinced you is the fastest way to make no progress on either.
Track the Volume, Not Just the Split
Both splits can fail the same way: you run the layout perfectly and your weekly volume per muscle is still wrong, because sets are being counted in your head. Push day had four sets of chest instead of eight. Upper B skipped arms three weeks running. The split looks right and the numbers are not there.
WinGym Exercises exists to close that gap. Log every set, every rep, every weight, then filter by muscle group and see your actual weekly volume for chest, back, quads, or anything else. If PPL is supposed to give your shoulders 16 sets a week and the app shows 9, you have found the problem before it costs you another month.

The Bottom Line
Push Pull Legs and Upper/Lower build the same muscle when they are run as designed, because they hit the same two levers: every muscle twice a week and 10 to 20 hard sets per muscle. The decision is about days, not about which split is secretly better.
Four days: Upper/Lower, and do not let anyone talk you into a 4-day PPL. Six days with real recovery: PPL. Five days: PPLUL, and stop choosing. Then hold the split for a season, drive progressive overload on every working set, and track the volume so you know the split is delivering what it promised.
The split is the shape of the week. The sets are what build the muscle.
