The upper/lower split: a complete guide and 8-week plan

You train three or four times a week and still work out what to do on the drive to the gym? The upper/lower split solves exactly that. You divide the body into two sessions — upper and lower — and train each of them twice a week.

What follows is a plan rather than a discussion. You get the weekly layout, the exercise list, the sets and reps, and an eight-week progression you can copy into your phone and use straight away.

Why this split works

Every muscle group gets two stimuli a week. After one good session a muscle stays primed to build for roughly a day and a half to two days, so two sessions cover the week better than one big one.

Second, fatigue lands in better places. Squat heavy and bench heavy on the same day and the back half of the session almost always suffers. Here your legs get a fresh day and your upper body gets its own.

Third, the split forgives you. Miss a day because of work and the week doesn't collapse — you shift the order along and carry on.

The weekly layout

The four-day version is the default:

• Monday — upper A
• Tuesday — lower A
• Wednesday — off, or a walk
• Thursday — upper B
• Friday — lower B
• Weekend — off

If three sessions is all you have, rotate them: upper – lower – upper one week, lower – upper – lower the next. Each half of the body then averages 1.5 sessions a week, which is still enough to make progress.

Leave at least 48 hours between two sessions for the same half.

How many sets per muscle group

For most people, growth happens somewhere between 10 and 20 hard sets per muscle group per week. Spread over two days, that is 5 to 10 sets per group per session.

If you have been lifting for less than six months, start at the bottom of that range. Ten weekly sets for chest or back sounds thin, but if those sets are genuinely hard it is plenty — and it leaves you somewhere to go when progress slows.

A hard set means the last few reps were a fight. Warm-up sets don't count.

The upper days

Upper A

• Bench press — 4 sets × 5–8 reps
• Barbell row — 4 × 6–10
• Incline dumbbell press — 3 × 8–12
• Lat pulldown — 3 × 10–12
• Lateral raise — 3 × 12–20
• Cable triceps extension — 2 × 10–15

Upper B

• Standing overhead press — 4 × 6–10
• Pull-ups or assisted pull-ups — 4 × 6–10
• Chest-supported row — 3 × 10–12
• Flat dumbbell press — 3 × 8–12
• Lateral raise — 3 × 12–20
• Biceps curl — 3 × 10–15

Keep one rule: match your pressing sets with pulling sets. If your shoulder already nags at you, look at what actually works in shoulder injury prevention before you start cutting weight off the bar, then reorder the session.

If your hands give out before your back does on rows and pull-ups, that isn't a reason to reach for straps on every set — two or three dedicated sets a week of grip training usually closes the gap.

The lower days

Lower A

• Back squat — 4 × 5–8
• Romanian deadlift — 3 × 8–10
• Leg press — 3 × 10–12
• Lying leg curl — 3 × 10–15
• Calf raise — 4 × 8–15

Lower B

• Deadlift, conventional or trap bar — 3 × 3–5
• Bulgarian split squat — 3 × 8–12 per leg
• Hack squat or goblet squat — 3 × 8–10
• Leg extension — 3 × 12–15
• Calf raise — 4 × 10–20
• Trunk: Pallof press — 3 × 8–10 per side

Deadlifts and Romanian deadlifts are the biggest single source of fatigue in this plan. If your back grumbles now and then, keep the reps low and pick a load where the last rep looks like the first. In practice, preventing back pain is mostly a question of dosage rather than exercise selection.

Load, proximity to failure and rest

Use one simple measure: how many reps you could still have done when you racked the bar. On compound lifts leave 2 to 3 in reserve; on isolation work, 0 to 1.

Rest 2 to 3 minutes after squats, deadlifts, bench and overhead press, and 60 to 90 seconds on isolation work. Cutting rest short isn't "more intense" — it just costs you reps on the next set.

Progress through double progression. If a lift is written as 3 × 6–8, add reps until all three sets hit 8. Only then add weight — 2.5 kg upper body, 5 kg lower — and drop back to 6.

The eight-week plan

Weeks 1–2: calibration. Run the sets as written but leave 3 reps in reserve on everything. The job is to record your loads, not to bury yourself. You will almost certainly underestimate what you can lift, and that is fine.

Weeks 3–5: adding. Add one set to the first two exercises of each session. Reserve drops to 2 reps. This is where most of the barbell progress happens.

Weeks 6–7: the peak. One rep in reserve on compounds, zero on the last set of isolation work. Your weekly set total is now at the top of your range. You'll feel it in your sleep and appetite.

Week 8: deload. Halve the sets, keep week six's loads, hold 3 to 4 reps in reserve. Don't skip it — personal bests usually turn up in the week straight after.

After week eight, don't restart from scratch. Take your end-of-week-seven loads, knock about 5 per cent off, and run the cycle again with slightly different accessory lifts.

A warm-up that doesn't eat the session

Five minutes on a bike or rower, then two to four ramp-up sets of the first lift: empty bar, then roughly 50, 70 and 85 per cent of your working weight. Eight to ten minutes in total.

Long static stretching before heavy sets won't help you. If you can't reach depth in a squat, or can't get your arms overhead without arching your back, mobility training pays off far better in its own slot than squeezed into a warm-up.

Knowing whether you're progressing

Write down every working set: weight, reps, how it felt. Without that you are guessing.

Three markers are enough. Weight times reps on the main lifts climbs across the block. Body weight moves in the direction you chose — around 0.25 to 0.5 per cent of body mass a week, up if you're building, down if you're cutting. And photos every four weeks, same light, same pose.

If none of those move for three weeks running, the cause is almost always sleep, food or too many sets — not the exercise selection.

Common mistakes

• Swapping exercises every week. You can't see progress without a fixed test.
• Jumping to 20 sets per muscle group in week one. You've spent your progression before you started.
• Taking the first lift to outright failure. It costs you the rest of the session and buys very little.
• Cutting the lower days short. Legs are the first to be skipped and the slowest to recover.
• Thirty minutes of running immediately before squats. Put cardio after upper sessions or on rest days.
• Less than 1.6 g of protein per kilogram of body weight and under seven hours of sleep. The plan can't work on that.
• Skipping week eight because you "feel fine". Feeling lags behind fatigue.

When to see a doctor

See a doctor if pain lasts more than two weeks despite reduced loading, travels down an arm or leg, comes with pins and needles, weakness or loss of grip or foot strength, or wakes you at night.

Chest pain or pressure, unusual breathlessness and dizziness on exertion are not gym problems — stop the session and get checked. If you have high blood pressure, a heart condition, diabetes or recent surgery, sort out the green light before you start, not after the first scare.

Common questions

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

At four sessions a week upper/lower is simpler because it always fits the calendar. Push/pull/legs only pulls ahead at five or six sessions. On three or four days, the difference in results is negligible.

How much cardio can I add?

Two or three easy sessions of 20 to 30 minutes a week won't get in the way. Put them on rest days or after upper-body sessions, never right before a lower day.

What if I miss a session?

Don't double up the next one. Shift the schedule by a day and keep the order. If you miss a whole week, repeat the last week you completed rather than jumping ahead.

How long can I stay on this split?

Years, as long as you rotate accessories and deload every six to eight weeks. You change the split when your number of free days changes, not when you get bored.

The short version

• Four sessions a week: upper A, lower A, upper B, lower B, with at least 48 hours between repeats.
• 10 to 20 sets per muscle group per week, split across two days.
• Compounds at 5–10 reps, isolation at 10–20, with 2–3 and 0–1 reps in reserve respectively.
• Double progression: reps to the top of the range first, then 2.5 kg upper or 5 kg lower.
• Weeks 1–2 calibrate, 3–5 add sets, 6–7 peak, 8 deload. Then repeat 5 per cent lighter.
• Log your sets. Without a training diary the plan is just a list of exercises.
