Training Splits Explained: How to Structure Your Gym Week

Choosing a training split comes down to how many days you can realistically train each week. If you can commit to two or three days, train full body. Four days, run an upper/lower split. Five or six days, run push/pull/legs. No split is universally best; the right split is the one you will actually follow.

I am Dr Matt Walley, and I co-founded Inception Gym Christchurch in 2022. I am on the floor most days, and the single most common question I get asked is not which exercise to do, it is how to structure the week. This guide is the answer I give in person, written down.

Key takeaways

• Match the split to your available days first, everything else second.
• Frequency matters more than the split's name: train each muscle twice a week where you can.
• The split is a framework, not a programme. Effort, exercise selection and progression fill it in.
• Pick one, commit for twelve weeks, then assess. Constant switching is the real killer of progress.

What is a training split?

A training split is simply the way you organise which muscles you train on which days. The split determines:

• How frequently each muscle group is trained per week
• How much recovery time each muscle group gets between sessions
• How much volume you can apply per session to specific muscle groups
• How your training week flows logistically

Here is the thing I wish more people understood before they agonise over the choice: the split is not the programme. It is the organisational framework that a programme sits within. I have watched two members run identical push/pull/legs splits on our floor and get completely different results, because one applied real effort and progressed the load, and the other drifted through the same weights for months. The split was never the variable that mattered.

The split you choose matters far less than whether you show up and add load to it. I have never once seen someone fail because they picked the "wrong" split; I have seen plenty fail because they kept changing it.

With that context in place, here are the main splits, their strengths, and who they suit.

Full body training

What it is

Each session targets the whole body: lower body compound movements, upper body push and pull movements, and accessory work, all in one session.

A full body session might include a squat, a bench press, a row, an overhead press, and two or three accessory exercises, trained three times per week.

Strengths

High training frequency: Each muscle group is stimulated three times per week. Research on training frequency consistently shows two to three sessions per week per muscle group produces superior hypertrophy outcomes compared to once per week, assuming volume is matched.

Efficiency for limited days: If you can only get to the gym two or three times a week, full body training ensures no muscle group is severely under-trained.

More practice on the big lifts: Squatting, pressing and pulling three times a week means three chances to rehearse technique. For beginners, that skill practice drives strength progress faster than any volume manipulation.

Limitations

Lower per-session volume per muscle: Because you train everything in one session, you cannot do as many sets per muscle group as a more specialised split allows without the session becoming impractically long.

Fatigue management: Training everything three times a week generates significant accumulated fatigue. Recovery demands are higher.

Session length: A properly structured full body session takes sixty to ninety minutes.

Best for

Beginners, people with three or fewer available training days, and those returning from a long break. If you are brand new, this is almost always where I point you. See our beginner's guide to starting a fitness journey for how to build the first twelve weeks.

Upper/lower split

What it is

The week is divided between upper body and lower body sessions. A typical structure is four days: upper, lower, rest, upper, lower, then rest.

Strengths

Excellent frequency-to-volume balance: Each major muscle group is trained twice per week, which hits the sweet spot in hypertrophy research. Upper body sessions allow more pushing and pulling volume than a full body session would permit.

Manageable session length: Sessions are typically sixty to seventy-five minutes.

Structural clarity: The upper/lower division is intuitive. You always know what you are training.

Good recovery structure: Training the same muscle again after two to three days lines up well with the muscle protein synthesis timeline.

Limitations

Requires four training days: Less flexible for unpredictable schedules, though our 24/7 access softens that considerably.

Lower body sessions are demanding: Squats and deadlifts in the same session create significant recovery demand, particularly for the lower back. Programming needs some care to avoid overlap.

Best for

Intermediate lifters with four consistent training days. Honestly, if someone on our floor asked me for one split to recommend to the widest range of people, this is it. It is the one I quietly steer most intermediates toward, because the twice-a-week frequency does the heavy lifting without demanding six days of your life.

Push/pull/legs (PPL)

What it is

Sessions are organised into three types:

• Push: chest, shoulders and triceps
• Pull: back and biceps
• Legs: quadriceps, hamstrings, glutes and calves

Typically run over six days (push, pull, legs, push, pull, legs, rest), though it can run over three or four days at the cost of muscle group frequency.

Strengths

High specificity and volume per session: A push session allows significant chest, shoulder and tricep volume that is impossible in a full body context.

Logical muscular grouping: Pushing exercises naturally use chest, shoulders and triceps together. Grouping them leverages that overlap and avoids fatigue spillover between sessions.

Six-day structure hits excellent frequency: Running PPL twice a week trains every muscle group twice, with volume spread over two sessions.

Popular for a reason: PPL is used by experienced bodybuilders and strength athletes because it works. It is a mature, well-tested approach.

Limitations

Requires five to six days for full benefit: Running PPL on three days only means each muscle is trained once per week, losing the frequency advantage.

Shoulder overlap on push days: Heavy pressing loads the front delts hard. Both heavy bench and heavy overhead press on the same day is a lot of shoulder recovery demand.

Best for

Intermediate to advanced lifters with five to six available training days and a specific goal of muscle growth. If you want to go deep on programming for size, our hypertrophy training guide pairs well with this split.

The "bro split" (body part split)

What it is

Each session targets a single muscle group or closely related pair: chest day, back day, shoulders day, arms day, legs day. Classic bodybuilding structure, five or six days a week.

Strengths

Maximum per-session volume: A dedicated chest day allows fifteen to twenty-plus sets without competing fatigue from other muscle groups.

Recovery advantage in theory: Each muscle group gets five to six days before being trained again.

Limitations

Low training frequency: Most current hypertrophy research suggests training each muscle group twice a week beats once a week when total volume is matched. A bro split typically gives once-per-week frequency, which leaves gains on the table for most natural lifters.

Fragile to missed days: Miss a session and your whole week's split is disrupted in a way a more flexible structure would not be.

Context matters: The volume a well-developed competitive bodybuilder applies in a single chest session, plus the recovery they sometimes need, is a different world from a natural intermediate lifter. I will be blunt here: I see more people cling to the bro split out of habit and gym tradition than out of any genuine fit for their goals. If you are natural and not yet advanced, it is rarely your best option.

Best for

Advanced lifters with five to six consistent days who have already built a solid foundation and want to bring up individual body parts. Not a starting point for most.

How do I choose the right split?

The right split is the one you will actually follow consistently. Beyond that:

How many days per week can you train consistently?

• 2 to 3 days: full body
• 4 days: upper/lower
• 5 to 6 days: PPL or upper/lower with an added day

What is your experience level?

• Beginner (under 12 months): full body or upper/lower
• Intermediate (1 to 3 years): upper/lower or PPL
• Advanced (3+ years): any, with conscious periodisation

What is your primary goal?

• General fitness and health: full body or upper/lower
• Muscle growth: upper/lower or PPL
• Strength: upper/lower, or a strength-specific programme within full body
• Body composition: any split with adequate volume and nutrition

If you are still not sure, come in and talk to me or one of the team. Working it out on the floor with someone who knows the equipment beats guessing from a blog. Book a free trial and we will sort it in person.

Frequency matters more than the split name

Research on training frequency generally concludes that training each muscle group twice a week is meaningfully better than once a week for hypertrophy, assuming volume is equated.

That does not make PPL inferior to full body. It means a six-day PPL, where each muscle is trained twice, outperforms a three-day PPL where each muscle is trained once. The split's name matters less than the frequency it produces. For more on how much work to actually do, see our guide to training volume and sets per week.

Equipment that supports any split

This is where an owner-operator's honesty helps. Plenty of splits fail not because of programming but because the gym is too busy or too under-equipped to run them. At Inception Gym we built to remove that excuse: 92+ pieces across 71 machine variants, 43 of them plate-loaded, plus a full free weight area with dumbbells to 70kg. We run 2 squat racks, and 24/7 access so your four or six day week is never held hostage by opening hours.

A dedicated push day can run flat machine press, incline dumbbell press, cable crossovers, machine lateral raises and tricep pushdowns without equipment conflict. A pull day uses the plate-loaded row, cable rows, lat pulldown, face pulls and barbell curls. Legs has the leg press, hack squat, Romanian deadlift, leg extension, leg curl and standing calf raise all available at once. When I designed the floor plan, running a full PPL split without waiting on a machine was one of the specific things I tested for.

Integrating nutrition

Your split determines your recovery demands, which determine your nutritional needs. A six-day PPL has different protein and calorie requirements than a three-day full body programme.

For most people the principles hold regardless of split: get enough daily protein (a food-first target of 1.6 to 2.0 grams per kilogram of bodyweight is a sensible range for most lifters), match calories to your goal, and arrive at sessions fuelled. Our members also get free body composition scans, which take the guesswork out of whether your split and nutrition are actually adding muscle or just weight. Book yours through our free body scan page.

The most important variable

Whatever split you choose, apply progressive overload within it consistently. A modest split with real progression will beat the theoretically optimal split run with stagnant weights every single time. I have seen this play out on our floor for four years now, and it has never once been the other way around.

Choose a structure that fits your schedule. Commit to it for at least twelve weeks before you assess or adjust. Track your sessions so you can see the load going up.
