How to choose a workout split for a client

Most coaches choose the split before they know anything useful about the client. Push/pull/legs because that is what you run, or upper/lower because the last client did well on it, and then the week gets built backwards from that decision. Six weeks later the client is training three days out of the five you wrote and half the program never gets touched.

The split is not the first decision. It is the last one, and it is mostly determined by the answers to three questions you should ask before you open the builder: how many days will they train, what are they training for, and what can they recover from. In that order.

Start with the days they will actually train

Not the days they say. The days their calendar has room for after work, commute, kids and whatever else already owns their evenings.

Ask it concretely. "Which days of the week, and at what time?" gets a truer answer than "how many times a week can you train?", because the first question forces them to look at a real week and the second lets them answer with an aspiration. If they cannot name the days and the times, they do not have four sessions available — they have a wish for four sessions.

Then take off one. A client who names four realistic slots will train three most weeks and four in a good week. That is not pessimism, it is what the first eight weeks of any program look like once a sick kid and a work trip land in it. Program for the number they will hit on a bad week and let the extra session be a bonus, not a failure.

This matters more than any other input because everything else in the program is downstream of it. Frequency, volume per muscle group, how often you can hit a lift and still progress it — all of it is set by the number of sessions, and the split is only the arrangement you choose to fit them in.

The split that fits the days

Here is the decision, laid out. The left column is the honest number of sessions per week. The right column is what you give up, because every split costs something and coaches rarely say what.

Two things fall out of that table. Below four days, the split chooses itself — you run full body because there is no other way to hit each muscle group twice. Above four days, you have options and none of them are better than the others on the numbers alone; you are choosing on what the client enjoys and what their recovery supports.

The descriptions of each split — how the sessions are actually laid out, and who each one suits — are in workout splits explained. This article is about matching one to a person.

Then the goal, and it moves the split less than you expect

Once the days are set, the goal changes the contents of the sessions far more than the shape of the week.

A hypertrophy client and a strength client on four days both run upper/lower. The strength client's lower day opens with a squat at a prescribed load and five sets of accessory work behind it; the hypertrophy client's lower day is six exercises with more total sets and less rest. Same split, different program.

The goals that genuinely change the split are the ones with a skill component. A client training for a powerlifting meet needs to squat, bench and deadlift often enough to keep the movement pattern sharp, which pushes you towards a split organised around the lifts rather than around muscle groups. A client running four times a week and lifting twice needs the lifting arranged so the hard leg session is not the day before their long run. Endurance and technical goals constrain the calendar; a fat-loss or muscle-gain goal mostly does not.

For general fat loss, the split is close to irrelevant. Adherence and the food side decide that outcome, and a client who trains three days of full body while eating in a deficit will get further than one who runs a perfectly arranged six-day split and skips half of it.

Then recovery, experience and age

The third filter is what the client can absorb between sessions, and this is where coaches overreach.

A beginner does not need a six-day split. They need the movements repeated often, which is what full body gives them, and they will make progress on two sets where an advanced lifter needs six. An advanced lifter needs the higher frequency because their per-session capacity is capped — they cannot do enough productive work for a muscle group in one session, so it has to be spread.

Sleep, stress and job type belong in this decision. A client sleeping five hours with a young baby does not get a six-day split no matter how much they want one. Someone on their feet all day on a worksite is starting each session with fatigue that a desk worker does not have. Older clients generally need more days between hard sessions for the same muscle group, which usually means fewer, better-organised sessions rather than more.

Two practical checks. If the client's performance on a lift is lower on the second session of the week than the first, week after week, the frequency is too high for their current recovery. And if their effort ratings are drifting up while the weights stay flat, the program is accumulating fatigue faster than they are clearing it — which is a deload conversation, not a split change.

The client who says four days and trains two

When a four-day program gets two sessions a week, the client does not train days one and two of a tidy rotation. They train day one twice, or they do whichever session they like most, or they start day three, get lost, and do their own thing. The program stops describing what is happening.

Two fixes, and you use both.

First, re-program to the truth. Move them to a two or three day full body layout so that any two sessions they complete still cover the whole body and still hit the main lifts twice. A full body program partially completed is a worse full body program. A four-day split partially completed is not a program at all.

Second, make the sessions order-independent where you can. If each session stands alone rather than depending on the one before it, a missed day is a missed day rather than a derailment. This is a small change in how you write the week and it removes most of the damage that skipping causes.

Have the conversation plainly: "You have been getting two sessions in, so I have rebuilt the week around two. If you get a third, here is the one to add." That reads as the coach paying attention, not as a demotion.

When every session has to fit in 45 minutes

In 45 minutes, most clients get through five to six exercises if the rest periods are honest. That number is the design constraint. Work back from it:

• Two hard compounds, then everything else. Give the long rest periods to the lifts that need them and run the accessories at shorter rest.
• Pair non-competing exercises. Alternating a set of rows with a set of split squats gets the same work done in noticeably less time and does not compromise either lift.
• Cut the exercise count, not the sets. Three exercises done properly beats six rushed ones, and it is the sets per muscle group that drive the adaptation.
• Prescribe effort rather than a fixed number of sets to failure. Telling a client to stop two reps short keeps the session on schedule and keeps them from turning the last exercise into a twenty-minute event. RPE and RIR both work here; pick one and stay with it.

With a 45-minute cap, upper/lower and full body both work; push/pull/legs starts to struggle because leg day was never going to fit. That is the only case where the time cap genuinely rules a split out.

Home gyms and limited equipment

Equipment does not change the split as often as coaches assume. It changes exercise selection, which is a different problem.

A client with a barbell, a rack and adjustable dumbbells can run any split in the table above. A client with dumbbells and bands only can too — they will need more sets to reach the same stimulus, because the loading tops out, but the shape of the week is unaffected.

Where equipment does force your hand is when a whole movement pattern is missing. No way to hinge under load, no pulling apparatus, no leg equipment beyond bodyweight. In that case the split follows the equipment rather than the muscle groups: build the week around what they can actually load, add the missing pattern back through whatever partial option exists, and do not pretend the program is balanced when it is not.

The other equipment case is the shared home gym or the busy commercial gym at 6pm. If the client cannot count on a rack being free, avoid programs where a whole session hinges on one piece of equipment. Write an alternative into the session so they substitute rather than skip.

If you are running this across a roster, the practical answer is to build the layout once and reuse it. Fitsly lets you build a program and deliver a per-client copy, so you can adjust one client's week without touching the version everyone else is on — how programs work has the detail.

Why the split matters less than everyone thinks

Once each muscle group is trained roughly twice a week and the weekly set count is in a sensible range, the arrangement of those sets across the week is a minor variable. A client doing 12 sets for back across two upper days and a client doing 12 sets for back across a pull day and a full body day will get similar results, assuming both actually train.

The reason split choice feels important is that it is the most visible decision. It has a name, clients ask about it by name, and it is the thing you can point at in a program document. That makes it a good conversation and a poor lever.

The levers that actually move results, roughly in order:

1. Turning up. Sessions completed per month beats every programming variable combined.
2. Weekly volume per muscle group in a sensible range — see how much volume clients actually need.
3. Proximity to failure. Sets taken close enough to matter. Most clients train further from failure than they think, which is why teaching RPE properly changes more than a new split will.
4. Progression over time. Something going up — load, reps, sets — across the block.
5. Exercise selection that suits the client's leverages and does not hurt.
6. The split. Last, and by some distance.

This is worth saying to clients directly, because a client who thinks the split is the secret will keep asking to change it, and every change resets the progression data you were building.

Review the split at four weeks, not four days

Set a review point when you write the program and tell the client what you will be looking at.

At four weeks you have enough to judge. Look at sessions completed against sessions programmed first — if that is under 75%, the split is wrong for their week regardless of anything else, and the fix is fewer days rather than a different arrangement. Then look at whether the main lifts moved at all. Then look at what they have to say about it, which is a real input, because a client who dislikes their week trains it less.

Most of the time the review says the split is fine and the client trained three days out of four. That is a scheduling conversation, and it is the one worth having.
