How an upper/lower split works, why 4 days a week is the sweet spot, a full sample week with sets and reps, and how to progress it for strength and muscle.
An upper/lower split alternates upper-body days (chest, back, shoulders, arms) with lower-body days (quads, hamstrings, glutes, calves). The standard version is 4 days a week: upper, lower, rest, upper, lower, which trains every muscle twice a week with sessions short enough to finish in about an hour. For most people who can train 4 days a week, upper/lower is the best balance of frequency, recovery, and time.
If full body feels like too much in one session and push/pull/legs needs more gym days than you have, upper/lower sits in the middle. It is the split many coaches default to for intermediate lifters, and it works just as well for beginners who can train four days a week.
Here is how it works, a sample week you can start on Monday, and how to keep it progressing.
An upper/lower split alternates upper-body and lower-body sessions, usually four times a week. The two session types are:
You alternate them through the week. With four sessions, every muscle gets trained twice.
Four days a week is the standard upper/lower setup, because it trains every muscle twice. Two, three, five, or six days also work.
| Days per week | Layout | Each muscle trained |
|---|---|---|
| 2 | Upper, lower | Once a week |
| 3 | Upper, lower, upper (then lower, upper, lower next week) | About 1.5 times a week |
| 4 | Upper, lower, rest, upper, lower | Twice a week |
| 5 to 6 | Upper/lower repeated, or add an arms or weak-point day | 2 to 3 times a week |
The 4-day version fits the evidence well. A 2016 meta-analysis by Schoenfeld and colleagues found that training each muscle at least twice a week led to more growth than once a week. Upper/lower gets you there with four sessions instead of six.
Not inherently. A 2024 meta-analysis by Ramos-Campo and colleagues pooled 14 studies and found split and full-body routines produced similar strength and muscle gains when weekly volume was matched. The best split is the one that fits your week.
Where upper/lower shines is practicality:
If you are choosing between options for the first time, our beginner workout split guide compares all three, and our push/pull/legs guide covers the 6-day option.
A typical upper/lower plan runs upper, lower, rest, upper, lower, with 4 to 6 exercises per session.
This 4-day plan uses a heavier first upper and lower day and a moderate second pair. Both days in each pair hit the same muscles with different exercises and rep ranges.
| Day | Session | Exercises |
|---|---|---|
| Monday | Upper 1 (heavier) | Bench press 3 × 5 to 8, barbell row 3 × 6 to 10, overhead press 2 × 6 to 10, pull-up 3 × 6 to 10, curl 2 × 8 to 12 |
| Tuesday | Lower 1 (heavier) | Squat 3 × 5 to 8, Romanian deadlift 3 × 6 to 10, walking lunge 2 × 8 per leg, calf raise 3 × 8 to 12 |
| Wednesday | Rest | |
| Thursday | Upper 2 (moderate) | Incline dumbbell press 3 × 8 to 12, lat pulldown 3 × 10 to 12, seated cable row 2 × 10 to 12, lateral raise 3 × 12 to 15, triceps extension 3 × 10 to 15 |
| Friday | Lower 2 (moderate) | Leg press 3 × 10 to 15, hip thrust or deadlift 3 × 8 to 12, leg curl 3 × 10 to 15, leg extension 2 × 12 to 15, calf raise 3 × 12 to 15 |
| Weekend | Rest or light cardio |
That gives most muscles around 10 to 14 hard sets a week, in line with the 2017 dose-response meta-analysis by Schoenfeld, Ogborn, and Krieger, which found more weekly sets were associated with more growth.
Strength gains favour heavier loads, while muscle growth happens across a wide range of loads when sets are hard. A 2017 meta-analysis by Schoenfeld, Grgic, Ogborn, and Krieger found greater 1RM gains with heavy loads but similar muscle growth between low- and high-load training taken to failure. Splitting the week into a heavier and a moderate pair gives you both.
Progress an upper/lower split with double progression: add reps within a range, then add weight once you reach the top. On every exercise:
Use the smallest realistic jump: 2.5 lb plates per side on a barbell, 5 lb per hand on dumbbells, about 10 lb on machines. Our double progression guide walks through worked examples. If a lift stalls three sessions running, take a lighter week before pushing again.
The most common upper/lower mistakes are overloading upper days, skipping hinges on lower days, and not tracking.
Alexandros is a personal lifting coach you talk to in a chat, currently in early access. Log "Upper 1: bench 3 × 7 at 165, row 3 × 9 at 135, last bench set was a grind" and it records every set with an effort rating, very easy to max effort, or reps in reserve if you know them. When Upper 1 comes around again, it tells you what to lift using double progression with realistic increments for each piece of equipment, and it plans a deload after three flat sessions. You can ask "What should I do today?" for a session plan, or "How has my squat progressed?" for a chart of top weight, estimated 1RM, or volume.
Yes. If a beginner can train four days a week, upper/lower trains every muscle twice, keeps sessions manageable, and teaches the main lifts with plenty of practice. With only three days, full body is usually the better fit.
Yes. Alternate weeks: upper, lower, upper one week, then lower, upper, lower the next. Each muscle is trained about 1.5 times per week on average, which still works well.
Pick upper/lower if you can train about four days a week, and PPL if you can reliably train five or six. Research does not show one split building more muscle than another when weekly sets are matched.
About 50 to 75 minutes, including warm-up sets and 2 to 3 minutes of rest on compound lifts. Upper days usually run a little longer because they include more exercises.
Yes. A fifth short session for arms, shoulders, or a lagging muscle works well, as long as your main lifts keep progressing. If they stall, the extra day may be eating into your recovery.
