An upper lower split is a routine that divides training into upper-body sessions and lower-body sessions. In the most common version you train 4 times a week, alternating upper and lower, so each muscle group is stimulated twice a week. It is the ideal bridge between a beginner's full-body plan and more fragmented splits: it keeps frequency high while increasing per-group volume. It is perfect for intermediates who can train 4 days. This guide explains the structure, gives you a ready-to-use example, and shows how to progress.
How the upper lower split is structured
The concept is simple: you divide the body into two macro-blocks.
- Upper: chest, back, shoulders, biceps, triceps. That is, all the upper-body pushes and pulls.
- Lower: quads, hamstrings, glutes, calves, plus core. That is, squats, hip hinges and leg accessories.
Over 4 weekly sessions the classic rotation is: Upper A, Lower A, rest, Upper B, Lower B, rest, rest. This way you train upper twice and lower twice a week, with at least one recovery day between sessions hitting the same muscles.
Compared to full-body, the upper lower concentrates more volume on each area per session, letting you add exercises and sets without stretching the workout endlessly. Compared to more fragmented splits like push/pull/legs, it keeps a 2x weekly frequency per group, which much research points to as beneficial for growth.
Who it suits
The upper lower is the natural choice at a specific phase of the journey.
- Intermediates: those who already have months of full-body behind them, master the technique of the big lifts, and need more volume to keep progressing.
- Anyone training 4 days a week: it is the session count the upper lower is designed around. With 4 days the math works perfectly: 2 upper + 2 lower.
- Those wanting balance between frequency and volume: it offers the best of both worlds, more volume than full-body but higher frequency than a classic split.
If you train only 2-3 times a week, stay with full-body, which is more efficient at that point. If you are an absolute beginner, start from the beginner plan. If you can train 5-6 times and seek maximal specialization, consider a 5-day split or push/pull/legs.
The push/pull balance
The great advantage of a well-built upper lower is balance. In the upper session you must carefully balance pushes (chest, shoulders, triceps) with pulls (back, biceps). A classic intermediate mistake is training the "mirror side" too much (bench and shoulders) while neglecting the back, causing postural imbalances and plateaus.
The rule of thumb: in the upper session, as many pull sets as push sets, or even slightly more. A healthy ratio is 1:1 or 1:1.2 in favor of pulls. The same applies to the lower body: balance quad-dominant work (squat, leg press) with hamstring- and glute-dominant work (Romanian deadlift, hip thrust, leg curl). Many develop the quads well and neglect the posterior chain: the upper lower gives you room to fix it.
| Area | Push pattern | Pull pattern |
|---|---|---|
| Upper | Bench, overhead press, chest press | Row, lat pulldown, pull-ups |
| Lower | Squat, leg press, lunges | Romanian deadlift, hip thrust, leg curl |

Managing 2x weekly frequency per group
The core of the upper lower's effectiveness is that each group works twice a week. To exploit it without overloading:
- Distribute the volume: instead of doing all your chest sets in one day, split them between Upper A and Upper B. This improves the quality of every set because you arrive less fatigued.
- Vary the angles: use session A and session B to stimulate the same muscle with different exercises (for example flat bench in A and incline or chest press in B).
- Respect recovery: with 2 upper and 2 lower you need at least a couple of weekly rest days. Do not cram the 4 sessions into 4 consecutive days.
- Control total volume: aim for roughly 10-18 weekly sets per large group, split across the two sessions. The topic is explored in the guide on how many sets per muscle group.
Progression in the upper lower
As an intermediate, pure linear progression (adding load every session) starts to slow, so you need a slightly finer approach.
- Double progression: work in a range (for example 6-8 reps). When you hit the top number on all sets with clean technique, add load and restart from the low number.
- Systematic progressive overload: whether it is a rep, a small load, or one more set, every week you seek a measurable improvement. It is the principle explained in the progressive overload guide.
- Periodic deload: every 5-8 weeks reduce volume and loads for a week and shed accumulated fatigue.
- Track everything: without a load log you cannot tell if you are really progressing. A digital training log makes the trajectory visible.
When even the upper lower stops producing progress (usually after many well-programmed months), the next step is increasing frequency or specialization with a 5-6 day split, managing load with true periodization.
Variants: upper lower on 3, 5 and 6 days
Four days is the reference format, but the upper/lower structure is flexible and adapts to different schedules.
- 3 days (alternating weeks): train upper, lower, upper one week and lower, upper, lower the next. This way per-group frequency oscillates between 1.5 and 2x. It is a good option for those who cannot guarantee four fixed sessions but want more volume than full-body.
- 5 days: add an extra session, often an "upper" or "lower" dedicated to a weak point. Frequency rises slightly but you must manage recovery carefully to avoid accumulating fatigue.
- 6 days: three upper and three lower. At this frequency, however, many athletes prefer to move to a more specialized 5-day split or to push/pull/legs, which distribute volume better across many sessions.
The 4-day version remains the most balanced for most intermediates: enough volume, guaranteed double frequency, sufficient recovery. Change the format only if your weekly availability truly requires it.
Common mistakes in the upper lower
- Skewing toward pushes: filling the upper sessions with bench and shoulders while neglecting the back leads to postural imbalances and a plateau on all pushing movements. Balance push and pull.
- Cramming the 4 sessions in a row: without interspersed rest days, recovery breaks down and quality drops. Distribute the workouts across the week.
- Neglecting the posterior chain: in the lower sessions, many do a lot of squats and leg press and little Romanian deadlift, hip thrust and leg curl. Hamstrings and glutes fall behind.
- Unmanageable volume: suddenly doubling the sets compared to full-body leads to chronic fatigue. Increase volume gradually and monitor recovery.
- Not periodizing: as an intermediate, linear progression ends. Without deloads and a minimum of programming, you hit a plateau. Use double progression and deload weeks.
Build your upper lower and follow it with a method
The upper lower split is the routine that carries much of the intermediate journey: double frequency, adequate volume, balance between push and pull. The decisive factor, as always, is consistency measured over time. You can create a free Athleex account and log your 4 weekly sessions from your phone, keeping an eye on loads, volume and progression, or find a personal trainer to build the upper lower around your weak points and manage its periodization. The structure is excellent: make it yours with data and consistency.
FAQ
Who is the upper lower split for?
The upper lower is the ideal choice for intermediates who can train 4 times a week. It assumes solid technique on the big lifts and the need for more volume to keep growing after the beginner phase. With 4 sessions you alternate two upper-body workouts and two lower-body ones, training each group twice a week. If you train only 2-3 times, full-body is more efficient; if you can do 5-6 sessions seeking maximal specialization, consider a split like push/pull/legs. The upper lower is the bridge between these two worlds.
How many times a week do you do the upper lower?
The classic version uses 4 weekly sessions: two upper and two lower, alternated with recovery days (for example upper, lower, rest, upper, lower, rest, rest). This way each muscle group is trained twice a week, a frequency research points to as effective for growth. There are 3-session variants (rotating the areas week to week) or 6-session ones for those with more time, but 4 days remains the format the upper lower is designed around and the most balanced across frequency, volume and recovery.
Is the upper lower or push/pull/legs better?
It depends on frequency. The upper lower works great on 4 days and keeps 2 weekly stimuli per group with a simple structure. Push/pull/legs shines on 6 days, allowing very high per-group volume and maximal specialization. On 4 days the upper lower is usually superior because it guarantees 2x frequency, while a push/pull/legs on only 3-4 days drops to 1-1.5 stimuli per group. The rule of thumb: up to 4 sessions choose upper lower, from 5-6 sessions consider push/pull/legs.
How do I balance push and pull in the upper lower?
In the upper session give pulls (back, biceps) at least as many sets as pushes (chest, shoulders, triceps), or slightly more: a healthy ratio is 1:1 or 1:1.2 in favor of pulls. This prevents the postural imbalances typical of those who train chest and shoulders too much while neglecting the back. The same applies to the lower body: balance quad work (squat, leg press) with posterior-chain work (Romanian deadlift, hip thrust, leg curl). Good balance improves posture, joint health and, over the long run, even the loads you can lift.
Can I build muscle with the upper lower split?
Yes, the upper lower is an excellent hypertrophy routine for intermediates. The combination of 2x frequency per group and adequate per-session volume creates ideal conditions for growth: you accumulate weekly volume in the effective range, split across two sessions, exploiting a repeated stimulus on protein synthesis. Compared to full-body you can dedicate more exercises and sets to each group without endless workouts. The key, as with any plan, remains progressive overload week after week and nutrition with adequate protein to support muscle building.
