“Should I train my whole body in every session, or give each muscle its own day?” I hear this question almost every week, from beginners and from people who have been in the gym for ten years. The internet usually answers it with a strong opinion and a celebrity example. Real life is less dramatic, and the research is clearer than most of the arguments.
The short answer: both approaches build muscle and strength. What decides your results is how much quality work you do for each muscle across the week, how consistently you show up, and how well you recover. The best split is the one that fits your goal, your schedule, and your energy, and that you will still be doing in six months.
I’m Marko Vuleta, a personal trainer in Dubai and founder of trainersdubai.com. Below you’ll find what each style really does, what the science says, who should use what, and sample weeks you can start with.
First, what do the terms mean?
A full body workout trains all major muscle groups in one session, usually built around multi-joint lifts like squats, presses, rows, and hip hinges. You normally train three times a week, sometimes two or four.
A split routine divides the body across sessions. Common versions are:
- Upper/lower split (4 days): upper body one day, lower body the next, repeated.
- Push/pull/legs, or PPL (3 to 6 days): pushing muscles, pulling muscles, then legs.
- Body-part split, the classic “bro split” (5 days): chest, back, shoulders, arms, legs, one per day.
One thing to clear up: no split truly isolates a muscle. During a bench press your triceps and front shoulders work too, and during a row your biceps get plenty of stimulus. So a “chest day” still trains other muscles, which matters when you count how much work each one is really doing.
What the research actually says
For decades the debate was driven by opinion and by what champions did. Some of the great natural physiques of the early bodybuilding era, such as Reg Park and Steve Reeves, trained the whole body several times per week. Later, as bodybuilding magazines and pro champions popularised body-part days, splits became the default image of “serious” training. Neither fact proves much, because elite athletes differ in genetics, recovery, and (often) drug use.
Research gives a better answer:
- A 2016 meta-analysis found that training a muscle twice per week produced better muscle growth than once per week, when volume was matched.
- A later 2019 meta-analysis in the Journal of Sports Sciences looked at 25 studies and concluded that when weekly volume is the same, frequency does not make a meaningful difference to muscle growth.
- A study in resistance-trained men compared training three versus six times per week with equal volume and found similar results in both groups.
The practical takeaway is that the number of weekly hard sets per muscle matters more than which day you do them. A common guideline is roughly 10 to 20 hard sets per muscle per week for people who want to build muscle, and fewer for beginners. Frequency becomes a tool for fitting that volume into your week with good quality, not a magic variable on its own.
For general health, the World Health Organization recommends muscle-strengthening activity for all major muscle groups on at least two days per week. Both full body and split training meet that.
Full body training: pros and cons
Advantages
- Flexible. If life gets in the way and you miss a session, no muscle group is skipped for two weeks.
- Efficient for busy people. Two or three sessions a week can be enough to see real progress.
- Frequent practice of the main lifts. If you’re learning the squat, deadlift, or press, repeating them often helps your technique improve faster.
- Travel-friendly. A 45-minute full body session fits a hotel gym much better than a “leg day” that needs a full rack and machines.
- Good for beginners. You build a base of strength and movement skill without needing a complicated plan.
Drawbacks
- Fatigue builds up inside the session. By the last exercises you’re tired, so performance on those lifts can drop.
- Hard to add a lot of volume per muscle in one session. If you want to specialise (for example, bring up the legs or the shoulders), a full body plan makes it harder.
- Recovery can be a limit. Heavy squats and deadlifts three times a week are demanding, so the plan has to manage intensity across the week (one heavy day, one lighter day, one moderate day, for instance).
Split training: pros and cons
Advantages
- More focus per muscle. You can do more sets for fewer muscles in one session, with less competition for energy.
- More variety. It’s easier to rotate exercises and keep training interesting.
- Shorter sessions are possible when you split the body across more days (30 to 60 minutes each).
- Useful for specialisation. If you want to bring up a body part, a split gives you room for extra work.
Drawbacks
- Needs more days. A 5-day body-part split is hard to sustain with a demanding job or travel.
- Missed days hurt more. Miss chest day on a once-a-week split and that muscle waits two weeks.
- Low frequency can waste potential. Training each muscle once a week works only if that single session has enough volume and quality, which can leave you sore and under-recovered on one day and idle the rest.
- Easy to create imbalances if the plan overemphasises the muscles you like to look at.
The middle ground: the upper/lower split
For many people the best answer is neither extreme. An upper/lower split trains each muscle twice per week across four sessions. You get the frequency that research supports, more volume per session than full body, and a plan that is still manageable. It’s also the setup I use most often with clients who have four days to train.
| Full body | Upper/lower | PPL | Body-part split | |
|---|---|---|---|---|
| Days per week | 2 to 4 | 4 | 3 to 6 | 5 |
| Times each muscle is trained | 2 to 3 | 2 | 1 to 2 | 1 |
| Session length | 45 to 75 min | 45 to 60 min | 45 to 60 min | 40 to 60 min |
| Best for | Beginners, busy schedules, travel | Most people with 4 days | People with 5 to 6 days | Experienced lifters who like volume per muscle |
| If you miss a day | Little impact | Moderate impact | Moderate impact | Large impact |
| Recovery demand | High per session | Moderate | Moderate | Low per session, but high overall |
Which one should you choose?
Skip the debate and answer these questions honestly:
- How many days can you train consistently? Not in a perfect month, in a normal one. Two or three days: full body. Four days: upper/lower. Five or six: PPL or a hybrid.
- What’s your experience? Beginners progress fastest on simple, repeatable full body plans. More advanced lifters often need extra volume per muscle, which splits provide.
- What is the goal? For general fitness, health, and fat loss, full body or upper/lower is hard to beat. For maximising muscle size or lagging body parts, a split with 2x weekly frequency per muscle usually works best.
- How much do you travel or work odd hours? Full body handles disruptions best.
- What will you enjoy? The plan you follow beats the “optimal” plan you abandon.
If you’re returning after a break or you’re over 40, full body with moderate intensity and enough rest between sessions is a safe and effective restart.
Sample plans you can try
Full body, 3 days per week (Mon / Wed / Fri, alternate A and B)
- Workout A: squat 3×6-8, bench press 3×6-10, seated row 3×8-10, Romanian deadlift 2×8-10, lateral raise 2×12-15
- Workout B: deadlift or hip thrust 3×5-8, overhead press 3×6-10, pull-up or lat pulldown 3×8-10, lunge 2×8-10 each leg, curls and triceps 2×10-12
Upper/lower, 4 days per week (Mon upper / Tue lower / Thu upper / Fri lower)
- Upper: a press, a row, a vertical pull, a shoulder exercise, and arms, 3 sets each, changing the exact exercises between the two upper days
- Lower: a squat pattern, a hinge pattern, a single-leg exercise, calves, and core, with one heavier day and one higher-rep day
Progress by adding a rep or a little weight when you can complete all sets with good form, a method I explain in training progression. Keep 1 to 3 reps in reserve on most sets, and push closer to failure only on the last set of an exercise.

What works in practice: my experience with clients
Over the years I’ve trained 1770+ clients, from complete beginners to people who had been lifting for a decade. For clients who can only train three days a week, a full body plan has worked best for me, almost every time. One example: a client of mine, 49-year-old businessman who travels often, came to me after three years of doing a five-day body-part split inconsistently. He kept missing sessions and felt he was always behind. We switched to three full body sessions per week with squat, overhead press, row and hinge, and within 16 weeks he added 10 kg to his squat and finally trained every week without skipping. Motivation for training was notably better. Nothing about his genetics changed. What changed was that the plan finally fit his life.
For clients with four days, I usually go with an upper/lower split, which is also what I follow myself when my schedule allows. When I train for strength, I use one heavy and one lighter day for each half, and I’ve found that it gives me “better recovery and less joint stress than full body three times a week, especially after I turned 30.
Common myths
- “Splits are only for bodybuilders.” Not true. Upper/lower is a practical option for many ordinary gym-goers.
- “Full body training means light, endless sets on machines.” No. A good full body plan uses heavy multi-joint lifts with sensible volume.
- “You need to train a muscle to destruction for it to grow.” Hard sets close to failure matter, but you don’t need to be wrecked after every session.
- “Hormone spikes after a workout decide growth.” The short rise in hormones after training is not what drives results. Total volume, progression, protein, and sleep do far more.
- “You must change your split often to keep your muscles guessing.” Progressive overload is what drives results. Change exercises when you need to, not for the sake of change.
- The biggest mistake I see. The most common mistake I see in Dubai gyms is not choosing the “wrong” split. It’s changing the plan every two or three weeks. People start a full body routine, switch to PPL after 4 weeks because someone on Instagram recommended it, and then try an upper/lower plan a month later. No plan gets enough time to work, and they never track their weights, so they can’t tell whether anything is improving. When a new client tells me “nothing works for me”, the first thing I check is how long they stayed on each program and whether they wrote down their numbers. Usually the answer to both is less than a month and “no”.
Don't forget nutrition and recovery
Your split can be perfect and still fail without enough protein, calories that match your goal, and sleep. If you want a plan built around your own body and schedule, I offer personalised nutrition plans, and I’ve written about why sleep matters for fat loss.

Frequently asked questions
Is three days of full body training enough if I’m not a professional?
For most people, yes. Three well-planned full body sessions per week cover all muscle groups multiple times and are enough to build strength and muscle, especially in the first few years. Add a fourth day only if you recover well and you want to increase volume.
Which is better for fat loss, full body or split?
Neither is magic. Fat loss comes down to a calorie deficit, adequate protein, and training that preserves muscle. Full body is often easier to sustain with a busy schedule.
Is a bro split bad?
Not bad, but it’s not efficient for most people. It can work for experienced lifters who enjoy it and can do enough quality volume in a session. If you’d miss days, a 2x per week frequency is more forgiving.
Can I switch between full body and split?
Yes. Many people change plans with the season of life: full body when work or travel is heavy, upper/lower when they have more time.
How long should I stay on one routine?
Stick with a plan for at least 8 to 12 weeks, so you can see whether it is working. Change it when your progress stalls despite good sleep and nutrition, not when you get bored.
Do I need a trainer to choose a split?
You can start on your own, but a coach helps you pick the right plan, check your form, and adjust as you progress.

Final thoughts
The “full body or split” debate has less to do with right and wrong than with fit. Full body suits low-frequency schedules and beginners, upper/lower is a strong default for four days, and PPL or body-part splits reward people with the time and recovery for high volume. What matters most is steady progress, enough weekly volume, and a plan you can keep.

If I do 3x a week full body like this on video, will I look like you?! 😀
Is 3x a week full body training enough for someone who is not professional?
In most cases, yes, but depends on your goals and progress.
