Upper/Lower Split: A Complete 4-Day Guide

Quick answer: An upper/lower split divides training into upper-body days and lower-body days, run four times a week as two upper and two lower sessions. That schedule hits every muscle twice per week, the frequency research links to maximum growth, while keeping sessions short enough to finish in about an hour.

You have been running full body three days a week, and it works, but the sessions have grown long and you never quite finish arms.

Or you tried a six-day bro split and missed enough days that half your muscles got trained once a week, if that.

The upper/lower split is the structure most lifters land on when they want more volume than full body allows without the fragile schedule of a six-day plan.

What is an upper/lower split?

An upper/lower split separates your training into two session types: one for everything above the waist, one for everything below. You then alternate them across the week.

• Upper days. Chest, back, shoulders, biceps, and triceps. Presses, rows, pulldowns, and a little arm work.
• Lower days. Quads, hamstrings, glutes, and calves. Squats, hinges, lunges, and isolation.

Run four times a week, that gives you two upper and two lower sessions. Every muscle gets trained twice, which is the whole point of the structure.

It sits between full body and a body-part split. Full body trains everything every session at low volume. A bro split trains one area hard once a week. Upper/lower splits the difference: moderate volume per session, twice-weekly frequency, four manageable days.

If you are weighing this against other four and five day options, our comparison of push pull legs vs upper/lower covers that matchup directly.

Why does twice-a-week frequency build the most muscle?

Training a muscle twice a week is the sweet spot the upper/lower split is built around. The four-day version delivers exactly that without any scheduling gymnastics.

The 2016 meta-analysis by Schoenfeld, Ogborn and Krieger in Sports Medicine found that major muscle groups should be trained at least twice per week to maximise growth, and that training once weekly left gains on the table.

Here is the nuance that keeps upper/lower practical. A 2019 meta-analysis in the Journal of Sports Sciences found no significant difference between higher and lower frequencies once weekly volume was equated. In other words, twice a week clears the bar; going higher is optional.

That is exactly what makes a four-day upper/lower split so efficient. It meets the twice-per-week floor with the fewest sessions, then lets you stack enough volume per muscle to keep growing. For where that weekly volume target should land, see our guide on how many sets per week to build muscle.

Who should run an upper/lower split?

The upper/lower split suits the lifter who has outgrown full body but cannot reliably train six days. That covers most intermediates.

• You want four solid days. Four is the split's home turf and the schedule most working adults can actually keep.
• Full body sessions run too long. Splitting upper from lower halves each session's exercise list.
• You have a weak point to feed. Concentrating a muscle's volume into two focused days beats spreading it thin across five.

It is less ideal if you can only train two or three days, where full body still wins, or if you genuinely train six days and want the shorter sessions a push/pull/legs structure allows. Our full body vs push pull legs breakdown covers the lower-frequency end.

What does a 4-day upper/lower split look like?

The classic 4 day upper lower split runs Monday, Tuesday, Thursday, Friday, with rest baked into the middle and end of the week. Order the days so you never hit the same region twice in a row.

Varying the two upper and two lower days keeps the emphasis fresh: one upper day leads with a bench press, the other with an overhead press, so both movement patterns get a fresh, heavy exposure each week.

Sample upper day

This upper lower workout routine balances pushing and pulling volume so nothing gets neglected.

• Bench press: 4 sets
• Barbell row: 4 sets
• Overhead press: 3 sets
• Lat pulldown or pull-up: 3 sets
• Lateral raise: 3 sets
• Biceps curl: 2 sets
• Triceps extension: 2 sets

Sample lower day

• Squat: 4 sets
• Romanian deadlift: 3 sets
• Leg press or hack squat: 3 sets
• Leg curl: 3 sets
• Calf raise: 3 sets
• Ab or core work: 2 sets

Repeat the same template on your B days with the movement swaps noted above, and every muscle lands its two weekly sessions.

How do you program and progress an upper/lower split?

Progression is what turns a schedule into results. The split gives you the twice-weekly exposure; you still have to add stimulus over time.

Knowing how to program upper lower comes down to three levers.

• Add reps, then weight. Double progression is the cleanest method: work up the rep range at a given weight, then add load and start over. Our guide on double progression vs linear progression walks through both.
• Anchor each day with a compound. Lead upper days with a press and a row, lower days with a squat or hinge, then fill in isolation. The heavy compound sets the tone while you are freshest.
• Grow volume slowly. Start each muscle around 10 weekly sets across its two days and add a set or two every few weeks only if recovery holds.

Run the same template for at least eight weeks before judging it. Switching splits monthly resets your data and hides whether the plan was working.

For an upper lower split for muscle growth specifically, prioritise total weekly volume and progressive overload over exotic exercise selection. The split already handles frequency; your job is consistent, tracked overload.

How do you adjust for 3 or 5 training days?

The upper/lower split flexes cleanly to three or five days by rotating sessions rather than fixing them to weekdays. You alternate upper and lower continuously.

• Three days. Run Upper, Lower, Upper one week, then Lower, Upper, Lower the next. Each muscle averages roughly three sessions every two weeks, close enough to the twice-weekly target when you keep volume up.
• Five days. Add a fifth session, often an arms-and-weak-point day or a light pump session, on top of two upper and two lower. Many lifters instead blend structures here. Our push pull legs plus upper/lower hybrid guide covers that five-day combination.

The rotating approach means a missed day just shifts the sequence forward instead of blowing a fixed weekly plan, which makes upper/lower forgiving on a messy schedule.

How should you track weekly volume per muscle?

The upper/lower split lives or dies on one number you cannot see from inside a session: how many hard sets each muscle got across the week.

Two upper days can quietly become chest-heavy and back-light if you keep adding presses and skipping rows. Without a running total, you would never notice until a lagging muscle told you.

Here is how the common ways of keeping that record compare:

A notebook or notes app logs the workout fine, but adding up weekly sets per muscle is a manual chore you will skip. That is the gap worth closing.

A simple starting plan

1. Pick your four days. Monday, Tuesday, Thursday, Friday is the default. Space upper and lower so you never repeat a region back to back.
2. Build two upper and two lower templates. Vary the lead compound between the A and B days, bench versus overhead press, squat versus hinge.
3. Set a weekly volume target, starting near 10 hard sets per muscle, and confirm your four days actually deliver it.
4. Progress with double progression. Add reps to the top of your range, then add weight and reset.
5. Log every set from day one, so weekly volume per muscle is a number you can read, not a guess.

Track it without rebuilding your routine

You already log your sessions, in a notebook or your phone, and that habit is the hard part. The upper/lower split does not need you to abandon it for a rigid app full of menus.

Gym Note Plus turns the plain-text log you already write into structured, trackable progress. Type your upper and lower days the way you always have, and it does the counting:

• Weekly volume, per muscle, automatically. See whether both upper days really balanced push and pull, or whether one muscle is drifting low.
• Last session recall. What you pressed on Upper A last week is right there when you program this week's overload.
• No templates to rebuild. Switching a lower day's lead lift means typing a different exercise, nothing more.
• Your existing shorthand works. If you write squat 100kg 5,5,5, you already know how to use it.

To pressure-test your plan before committing, you can get a free private link to the workout plan optimizer, which maps what your split hits and flags where the volume is lopsided. Or paste a session into the free notes to workout translator to see your raw text become charts.

An upper/lower split is the cleanest way to train every muscle twice a week in four sessions. The schedule handles frequency; tracking your weekly volume is what turns it into growth.

Frequently Asked Questions

What is an upper/lower split?

An upper/lower split is a training structure that divides workouts into upper-body sessions and lower-body sessions. Upper days cover chest, back, shoulders, and arms; lower days cover quads, hamstrings, glutes, and calves. Run four times a week as two upper and two lower sessions, the upper/lower split trains every major muscle group twice weekly.

Is a 4 day upper lower split good for building muscle?

A 4 day upper lower split is one of the most effective structures for building muscle. It trains each muscle group twice per week, matching the frequency the 2016 Sports Medicine meta-analysis linked to maximum growth, while keeping sessions around an hour. That balance of frequency, volume, and manageable schedule suits most intermediate lifters aiming for hypertrophy.

How many days a week should you do an upper/lower split?

Four days a week is the standard for an upper/lower split, run as two upper and two lower sessions so every muscle is trained twice. The split also adapts to three days by rotating sessions across weeks, or to five days by adding an arms or weak-point session. Four remains the most common and balanced choice.

Is an upper/lower split better than push pull legs?

Neither an upper/lower split nor push pull legs is universally better; the right choice depends on your training days. An upper/lower split fits four days cleanly and hits each muscle twice weekly, while push pull legs suits five or six days with shorter sessions. Both build muscle equally when weekly volume per muscle matches.

How do you progress on an upper/lower split?

You progress on an upper/lower split using double progression: add reps within a target range at a fixed weight, then increase the load and restart the range. Anchor each session with a heavy compound lift, start around 10 hard sets per muscle each week, and add volume only when recovery allows. Track every set to confirm overload.

How long should an upper/lower workout take?

An upper or lower workout on this split typically takes 45 to 75 minutes, including warm-up and rest between sets. Compound lifts need two to three minutes of rest to be repeated at full effort, which drives most of the session length. Because each session covers only half the body, it stays shorter than a full-body workout.

Final Takeaways

• Four days is the split's home. Two upper and two lower sessions train every muscle twice a week.
• Twice per week is the growth floor. The upper/lower split meets it with the fewest sessions.
• Vary your A and B days. Alternate the lead compound so both push and pull, squat and hinge, stay fresh.
• Progress with double progression. Add reps, then weight, and hold the template for at least eight weeks.
• It flexes to three or five days. Rotate sessions instead of fixing them to weekdays.
• Track weekly volume per muscle. The split handles frequency; your log turns it into growth.
