The most effective way to split your upper body workout is to separate exercises by movement pattern, dividing your training into pushing movements (chest, shoulders, triceps) and pulling movements (back, biceps, forearms). This lets you train each muscle group with enough volume and intensity without running into fatigue problems that come from cramming everything into one session. There are a few ways to do this, and the best choice depends on how many days per week you train.
The Push/Pull Split
The most popular method for splitting upper body work is the push/pull approach. One day focuses entirely on pushing exercises: bench press variations, overhead presses, and triceps work. The other day covers pulling exercises: rows, pulldowns or chin-ups, and biceps curls. This works well because pushing and pulling use completely separate muscle groups, so training one has zero overlap with the other.
The push/pull split also pairs naturally with a legs day, creating a three-way rotation (push, pull, legs) that you can run twice per week across six training days, or once per week across three days. If you’re training four days a week, you might do push, pull, legs, then a combined upper body day, cycling the emphasis over time.
The Horizontal/Vertical Split
A less common but equally effective option is splitting by movement plane rather than push/pull. One session covers all horizontal movements, both pushing and pulling. That means bench press and rows share a day. The other session covers vertical movements: overhead pressing and pulldowns or chin-ups.
Horizontal pressing includes flat bench press, dumbbell bench press, and push-ups. Horizontal pulling includes cable rows, dumbbell rows, and TRX rows. On the vertical side, pressing means overhead dumbbell or barbell presses, while pulling means chin-ups, pull-ups, and lat pulldowns.
This approach works especially well for shoulder health because it naturally balances the push-to-pull ratio within each session. It also lets you pair opposing movements as supersets, which cuts your workout time significantly.
Why Supersets Work for Upper Body Splits
Whichever split you choose, pairing opposing muscle groups (chest with back, biceps with triceps) into supersets is one of the most time-efficient strategies available. Research published in the Journal of Functional Morphology and Kinesiology found that pairing exercises like bench press and rows allows active recovery between opposing muscle groups. You maintain the same weight and reps you’d achieve with traditional rest periods while cutting overall session time nearly in half.
The mechanism is straightforward: while your chest recovers, your back is working, and vice versa. This isn’t just about saving time. The data actually showed a slight increase in total repetitions when using supersets, likely because activating one muscle group primes the opposing group for better performance. The key is keeping the antagonist exercise at low-to-moderate effort so it doesn’t compromise your main lift.
Exercise Order Within Each Session
Regardless of how you split things up, start every session with your heaviest compound movements and finish with isolation work. Compound exercises like bench press, overhead press, rows, and pull-ups recruit multiple joints and large muscle groups. They demand the most energy and coordination, so you want to hit them while you’re fresh.
Isolation exercises like biceps curls, triceps extensions, and lateral raises go at the end. If you fatigue your triceps with pushdowns before attempting a heavy bench press, your bench numbers will suffer because your triceps assist in that movement. Save the smaller, single-joint exercises for after the big lifts are done.
A practical push day might look like: flat bench press, incline dumbbell press, overhead press, lateral raises, then triceps work. A pull day might start with barbell rows, move to pull-ups, then cable rows, face pulls, and finish with biceps curls.
How Many Sets Per Muscle Group
For building muscle, the target is 12 to 20 hard sets per muscle group per week. A “hard set” means a set performed close to failure, not a warm-up. A systematic review of resistance training volumes found this moderate range produced optimal hypertrophy in trained men. Going above 20 weekly sets didn’t produce better results for most muscle groups, with one exception: triceps responded better to higher volumes (above 20 sets), likely because they’re a smaller muscle that recovers quickly.
Biceps, interestingly, showed no additional benefit from high volume over moderate volume. Since your biceps already get significant work during every pulling exercise (rows, pulldowns, chin-ups), 2 to 4 direct sets of curls per session is usually enough to reach that 12-to-20-set weekly threshold when you count the indirect work.
Splitting your upper body across two or more sessions makes hitting these volume targets much more manageable. Trying to fit 12+ sets each for chest, back, shoulders, biceps, and triceps into a single session would take well over an hour and performance would tank toward the end.
Rep Ranges for Different Goals
Your rep range should match what you’re training for. The repetition continuum breaks down like this:
- Strength (1 to 5 reps): Heavy loads at 80% or more of your max. Best for compound lifts like bench press and rows where you want to build raw force production.
- Muscle growth (8 to 12 reps): Moderate loads at 60% to 80% of your max. The classic hypertrophy range that works for both compound and isolation exercises.
- Endurance (15+ reps): Lighter loads below 60% of your max. Useful for accessory work like face pulls or lateral raises.
These ranges hold true for both upper and lower body exercises. Most people benefit from mixing ranges within a session: heavier compound work in the 3-to-6 rep range early on, moderate hypertrophy work in the 8-to-12 range for secondary exercises, and higher reps for isolation finishers.
Training Frequency and Recovery
Muscle protein synthesis, the process that repairs and grows muscle tissue, spikes after a hard training session. It peaks at roughly double the baseline rate around 24 hours post-exercise, then drops back to near-normal levels by 36 hours. This means the growth signal from a single workout is largely spent within a day and a half.
This is the strongest argument for splitting your upper body and hitting each muscle group at least twice per week. If you only train chest on Monday, the growth stimulus has faded by Tuesday evening, and you’re waiting until the following Monday to trigger it again. Training chest on both Monday and Thursday keeps the growth signal elevated for a much larger portion of the week.
A push/pull split run twice weekly (four upper body sessions total) is ideal for this. If your schedule only allows three upper body sessions, alternating push and pull across the week still gives each muscle group a session every four to five days, which is a reasonable compromise.
Sample Weekly Layouts
4-Day Push/Pull (Most Common)
- Monday: Push (chest, shoulders, triceps)
- Tuesday: Pull (back, biceps, rear delts)
- Wednesday: Legs or rest
- Thursday: Push
- Friday: Pull
- Weekend: Legs and/or rest
3-Day Horizontal/Vertical
- Monday: Horizontal push + pull (bench, rows, push-ups, dumbbell rows)
- Wednesday: Legs
- Friday: Vertical push + pull (overhead press, pull-ups, lateral raises, pulldowns)
The 4-day push/pull split hits each muscle group twice per week and distributes volume more evenly across sessions. The 3-day horizontal/vertical layout works better for people with limited gym time who want balanced development in fewer sessions. Both approaches follow the same underlying principle: separate muscles that compete for recovery, group muscles that work together, and train everything frequently enough to keep the growth stimulus active throughout the week.
