The Best 4-Day Workout Routine: Upper/Lower Done Right
Four training days is one of the most productive setups a natural lifter can run. It trains every muscle twice a week, leaves room for accessory work, and still gives three full rest days. Organized as an upper/lower split, it is simple to follow and easy to progress for a long time.

The weekly layout
- MonUpper AHeavy press and row
- TueLower ASquat focus
- WedRestWalk or light cardio
- ThuUpper BIncline press and vertical pull
- FriLower BHinge focus
- SatRest
- SunRest
The mid-week rest day splits the week into two mini-blocks, so you arrive at the second upper and lower sessions recovered. If your week does not fit this exact pattern, any order works as long as you avoid three hard days in a row.
Upper days
| Upper A | Sets × reps | Upper B | Sets × reps |
|---|---|---|---|
| Bench press | 4 × 5–8 | Incline dumbbell press | 3 × 8–12 |
| Barbell or chest-supported row | 4 × 6–10 | Pull-up or lat pulldown | 4 × 6–10 |
| Overhead press | 3 × 6–10 | Seated cable row | 3 × 10–12 |
| Lat pulldown | 3 × 10–12 | Dips or machine chest press | 3 × 8–12 |
| Lateral raise | 3 × 12–20 | Rear-delt flye | 3 × 12–20 |
| Triceps pressdown | 2 × 10–15 | Incline curl | 2 × 10–15 |
| Curl | 2 × 10–15 | Overhead triceps extension | 2 × 10–15 |
Each upper day has as much pulling as pushing. That balance is what keeps shoulders healthy over years of pressing, and it builds the upper back that makes every press stronger.
Lower days
| Lower A | Sets × reps | Lower B | Sets × reps |
|---|---|---|---|
| Back squat | 4 × 5–8 | Romanian deadlift or deadlift | 4 × 5–8 |
| Romanian deadlift | 3 × 8–10 | Front squat or hack squat | 3 × 6–10 |
| Leg press | 3 × 10–12 | Walking lunge or split squat | 3 × 8–12 each |
| Seated leg curl | 3 × 10–15 | Leg extension | 3 × 12–15 |
| Standing calf raise | 3 × 10–15 | Seated calf raise | 3 × 12–20 |
| Cable crunch | 3 × 10–15 | Hanging knee raise | 3 × 10–15 |
Heavy compounds come first while you are fresh; isolation work comes last, where fatigue matters least. Leg days are demanding — keep rest periods honest, two to three minutes on the first two lifts.
Weekly volume and progression
Counting hard sets across the week, this plan lands most muscles in the range associated with strong growth:
Those are direct sets only. The glutes work hard in every squat, lunge and Romanian deadlift, and the arms and shoulders get heavy indirect work from every press and pull — the biceps alone assist in fourteen sets of rows and pulldowns — so their real totals are well above the direct numbers. If your arms are a priority, add a set to each arm exercise. Progress the compounds with small weight steps whenever you hit the top of the rep range on every set; progress accessories by adding reps first. Every six to eight weeks, or when performance drops across several lifts, take a deload week at half the sets.
Is four days right for you?
Four days suits lifters who have trained consistently for a few months, can recover from a bit more volume, and can reliably make four sessions a week. If you are brand new, a three-day full-body plan is a better start. If you want even more volume and can train five or six days, push pull legs is the natural next step.
Whatever you choose, the numbers in your log should go up for months. If they do, the plan is working — resist the urge to change it.
- Four days works beautifully as upper/lower: Mon, Tue, Thu, Fri.
- Every muscle is trained twice a week with three full rest days.
- Balance every press with a pull to protect the shoulders.
- Major muscles get 10 to 16 direct hard sets a week — enough for strong growth.
- Progress compounds with small weight steps and accessories with reps.
Frequently asked questions
Is upper/lower better than push pull legs?
For four days, usually yes. Push pull legs fits best at five or six days; upper/lower gives twice-weekly frequency in exactly four sessions.
Can beginners use a 4-day routine?
Yes, if recovery and schedule allow. Many beginners do very well on upper/lower after a few months of full-body training.
How many exercises per workout?
Five to seven. More than that usually turns into low-quality volume unless the session is very well managed.
How long should each session take?
About 60 to 75 minutes including warm-ups. Supersetting the arm and shoulder accessories can save ten minutes.
Can I do upper/lower on three days?
Yes, by rotating: upper, lower, upper one week and lower, upper, lower the next. Each muscle gets trained three times every two weeks.
