4-Day Upper/Lower Workout Split for Intermediate Lifters
After 6 to 12 months of consistent training, most lifters notice that a three-day full-body routine no longer works as well as it used to. The weights move up slowly, and further progress needs more training volume. At this stage, a 4-day upper/lower workout split is one of the best options: each muscle is trained twice a week, gets enough time to recover, and sessions don't drag on too long.
Why an upper/lower split suits intermediate lifters
Evidence suggests that training each muscle twice a week is usually more effective for growth than training it once. Traditional "one muscle per day" routines only hit each muscle once a week. An upper/lower split, by contrast, offers these advantages:
- Twice-weekly frequency: each muscle group is stimulated in two sessions per week.
- Built-in recovery: your legs rest while you train upper body, and vice versa.
- Strength plus size: one session of each type focuses on heavier loads, the other on higher reps.
- Flexible scheduling: four sessions a week leaves three days for rest, work and life.
Weekly schedule
A simple layout for a Saturday-to-Friday week looks like this:
| Day | Session |
|---|---|
| Saturday | Upper A (strength focus) |
| Sunday | Lower A (strength focus) |
| Monday | Rest or light cardio |
| Tuesday | Upper B (hypertrophy focus) |
| Wednesday | Lower B (hypertrophy focus) |
| Thursday and Friday | Rest, walking or a light hike |
If your work schedule doesn't allow this, move sessions around; just try not to train more than two days in a row.

In the last column, "RIR" means reps in reserve: how many more reps you could have done at the end of the set. RIR 2 means you stop the set when you have about two good reps left.

| Standing overhead press | 3 × 6 to 8 | 2 min | 2 |
| Pull-up or lat pulldown | 3 × 6 to 10 | 2 min | 1 to 2 |
| Barbell curl | 2 × 8 to 10 | 90 s | 1 |

| Standing calf raise | 3 × 8 to 12 | 60 s | 1 |
Upper B (hypertrophy)
| Exercise | Sets × reps | Rest | RIR |
|---|---|---|---|
| Incline dumbbell press | 3 × 8 to 12 | 2 min | 1 to 2 |
| Seated cable row | 3 × 10 to 12 | 90 s | 1 to 2 |
| Close-grip lat pulldown | 3 × 10 to 12 | 90 s | 1 |
| Dumbbell lateral raise | 3 × 12 to 15 | 60 s | 1 |
| Face pull | 2 × 12 to 15 | 60 s | 1 |
| Dumbbell hammer curl | 2 × 10 to 12 | 60 s | 0 to 1 |
| Overhead dumbbell extension | 2 × 10 to 12 | 60 s | 0 to 1 |
Lower B (hypertrophy)
| Exercise | Sets × reps | Rest | RIR |
|---|---|---|---|
| Conventional deadlift or hack squat | 3 × 6 to 8 | 3 min | 2 |
| Bulgarian split squat | 3 × 8 to 10 per leg | 90 s | 1 to 2 |
| Hip thrust | 3 × 10 to 12 | 90 s | 1 |
| Leg extension | 3 × 12 to 15 | 60 s | 0 to 1 |

How to progress: double progression
Without gradually increasing the challenge, no program works for long. The simplest method for intermediates is double progression:
- Each exercise has a rep range, for example 8 to 10.
- Start with a weight you can lift for at least 8 clean reps on every set.
- Each session, try to add one or two reps.
- When you hit 10 reps on all sets, add weight: about 2.5 kg for upper-body lifts and 5 kg for lower-body lifts.
- Start again from 8 reps with the new weight.
On heavy lifts like the squat and bench press, if you miss your reps two sessions in a row, check your sleep, nutrition and stress, and if needed drop the weight by 5 to 10 percent and build back up.
Deload weeks: smart rest
After every 5 to 7 weeks of hard training, plan a lighter "deload" week. Keep the same exercises but halve the number of sets or cut the weights by about 30 to 40 percent. A deload gives your joints, tendons and nervous system time to recover, and you usually come back stronger. If you feel constant fatigue, falling strength or joint aches earlier, bring the deload forward.
Warming up before each session
- 5 minutes on the bike, rower or a brisk walk
- Dynamic mobility: arm circles, hip openers, bodyweight squats
- 2 to 3 ramp-up sets on the first main lift, for example at 50, 70 and 85 percent of your working weight
Nutrition and recovery for a 4-day program
At the intermediate level, nutrition matters as much as training. Daily protein of about 1.6 to 2.2 grams per kilogram of body weight, a modest surplus of 200 to 300 kcal when building or a modest deficit when cutting, and 7 to 9 hours of sleep are the foundations. Estimate your calorie needs with the ProGym calorie calculator and adjust based on your weekly weight trend.
Common upper/lower split mistakes
- Piling on exercises: sessions longer than 75 to 90 minutes usually hurt the quality of the final sets.
- Coasting through Lower B: many people take the second leg day easy, but it's half of your weekly leg volume.
- Training to failure on heavy lifts: keep 1 to 2 reps in reserve on squats and deadlifts; save true failure for isolation moves.
- Program hopping: stick with one program for at least 8 to 12 weeks so progress is measurable.
Safety notes
If you feel sharp or shooting pain in a joint or your back during any movement, stop and see a physician or physiotherapist. People with high blood pressure, heart disease or a history of disc injury should check with their doctor before lifting heavy. On heavy bench presses and squats, always use a spotter or the rack's safety bars.
Summary
A 4-day upper/lower split for intermediate lifters trains every muscle twice a week, dedicates one session to strength and one to size, and allows enough recovery. Progress with double progression, deload every 5 to 7 weeks and take nutrition and sleep seriously. If you'd like the program tailored to your body and goals, get help from the ProGym online coaches.
Frequently asked questions
Is an upper/lower split better than a bro split for muscle growth?
For most non-professional lifters, training each muscle twice a week works better. An upper/lower split provides that frequency in four sessions, while a bro split usually trains each muscle only once.
How long does each session of a 4-day split take?
Including the warm-up, each session usually takes 60 to 75 minutes. If you're short on time, trim the isolation exercises at the end rather than the main lifts.
When should I switch from full-body to an upper/lower split?
Usually after 6 to 12 months of consistent training, when progress on a full-body routine has slowed and you can reliably train four days a week.
Can I add cardio to a 4-day upper/lower program?
Yes. Two or three light 20 to 30 minute cardio sessions on rest days or after upper-body sessions work well. Avoid hard cardio close to leg days.
