It’s possible to build a lot of muscle with no split routine at all. Full body workouts have their place, especially for beginners, for time efficiency and for “back to basics” strength training. But suppose you have a physique and visual aesthetics  goal and decided to go with a body part split. What is the best split routine for building muscle?

Despite what the “gurus” want you to believe, there’s no single best split routine for building muscle. You can build a lot of muscle with a variety of training splits. There are simply pros and cons of each one. If all the conflicting advice from training gurus has you horribly confused about how to set up your weekly split routine, everything will become clear as you read the Q & A post below…

Q: Dear Tom: Would a body part split yield greater muscle gains vs full body? For example, I’ve looked at a couple of options such as: Day 1: Legs and abs, Day 2: Chest, Shoulders and Triceps, Day 3: Back, Biceps, and Forearms, or even splitting it up to one body part a day like this: Day 1: Back, Day 2:  Chest, Day 3: Legs, Day 4: off (or just cardio), Day 5: Shoulders, Day 6: Arms, Day 7:  off (or just cardio). What’s more beneficial to someone who wants to add muscle and keep bodyfat levels low, in the shortest time possible?

best split routineBody part splits lost some popularity for a while in mainstream fitness. I was seeing split routines get criticized by certified personal trainers and sports training coaches all the time. Sometimes it was justifiable, given the context. But as I predicted, split routines have become popular again, at least some of them.

Despite the way training trends swing in cycles over the years, body part split routines actually have never gone anywhere. Competitive bodybuilders and physique athletes use them as their standard training method and always have.

That’s because body part splits are incredibly effective for muscle growth (hypertrophy). Split routines are superb for visual aesthetic and cosmetic goals. (Like when you want to compete, look like you compete, or just look good naked).

Bodybuilders are the most muscular and aesthetic athletes in the world. They also happen to carry the lowest body fat of all athletes at competition time. Is that what you want? Do you want to add muscle to specific places on your body, for Greek statue symmetry? If so, then don’t let anyone tell you otherwise –  split routines are a terrific option. The best.

How to set up your split routine? This could fill a whole chapter in a lifting book. But I’m going to give you a brief, yet complete summary below.

There are several popular split routines among bodybuilders and you mentioned two of them in your question (the 3 and 5 day split). I use a 4 day split, but all these methods can be effective.

The 3 day Split, antagonistic (3-day “classic muscle”)
Day 1: Chest, back
Day 2: Shoulders, Biceps, Triceps
Day 3: Quads, Hams

The 3 day Split, push-pull-legs (most popular for muscle-building)
Day 1: Chest, shoulders, triceps
Day 2: quads, hams, calves
Day 3: Back, biceps, forearms

The 4-day bodybuilder’s split (Tom’s choice for advanced bodybuilding)
Day 1: Chest, biceps
Day 2: Quads, hams
Day 3: Shoulders, Triceps
Day 4: Back, calves

The 5 day bodybuilder’s “bro” split (a body part a day)
Day 1: Chest
Day 2: Legs
Day 3: Shoulders
Day 4: Back
Day 5: Arms

* Abs and calves can be assigned a specific day. Or you can do them every other workout or even on off days.
* Possible weekly schedules for these splits are endless. A common way to do the 3 or 4 day split is 2 days on, 1 day off then repeat the cycle, or for higher frequency training, 3 on 1 off or 4 on 1 off.

The 4-day and 5-day advanced bodybuilding splits are not the kind of training usually recommended for athletes outside of physique sports. The 5-day split especially, has not been without controversy. (As evidenced by the “bro split” nickname, implying that only meatheads, aka “bros” would do this).

A 5-day split has you training one major muscle each day. Usually each muscle is only worked once a week and gets bombed with lots of exercises.  There has been some recent evidence that working each muscle so infrequently is not optimal. But even this split works great for hypertrophy as long as the total weekly volume (number of sets per muscle group) is high enough.

Personally, my default training program is a 4 day split, and my second favorite is the 3 day split. (Though I’ve used almost every type of training program over the 3+ decades I’ve been training).  I also occasionally go back to more “basic” strength training routines for variety.

It’s important to note that 3, 4, and 5 day body part splits are definitely bodybuilding-focused routines. I’m talking specifically about bodybuilding literally, as in the competitor or person with visual aesthetic goals.

All your training decisions should be made in the context of your goals. Depending on your goals, there are advantages or disadvantages to body part split routines.

Advantages of body part splits:

1. Energy allocation.

If you only have to train one body part in a session, you can put 100% energy into that muscle. If you have to train all your major muscle groups in one session, that is extremely energy-draining. Whatever is done last in the workout will always suffer compared to what is done first. This is a particularly important consideration for “priority training” when one body part is lagging in comparison to others.

2. Mental concentration.

Many bodybuilders say that beyond physical energy allocation, they can mentally focus better with only one or two body parts to train per session. The mind to muscle connection is important in physique training.

3. Time to do more volume.

The beginner doesn’t need a lot of volume. The advanced bodybuilder on the other hand, can not only handle more volume but will often thrive on it. If you’re doing your whole body or even half your body per session, you can only do so much volume without the workouts dragging out for hours. To train with the desired amount of volume and keep the workouts a reasonable length, this calls for splitting routines.

4. Time to do more exercises/angles.

Split routines not only allow you to do more volume in terms of number of sets, you can also do multiple exercises. An athlete like a football player doesn’t care about rear deltoid development or whether the lateral deltoid has enough width and “cap” – he is concerned with strength and performance. A bodybuilder on the other hand, wants to develop a muscle from every angle. On shoulder day for example, that would include front, side and rear deltoid exercises. On a basic mass/ strength program that only works the compound basic exercises, one might only do a military press. That can produce a good amount of size, but doesn’t work every aspect of the muscle and doesn’t allow the bodybuilder to specialize on one part of a muscle that might be lagging (example: rear delt exercise), in order to develop symmetry.

Disadvantages of body part splits:

1. Body part split routines are not appropriate for all athletes.

Athletes (outside of physique sports) focus on movement patterns not individual muscles. For example: horizontal push, vertical pull, rotation, etc. Strength athletes usually focus on lifts, not individual muscles. For example: bench day, squat day and deadlift day, with assistance work done after the main lifts.

2. Body part split routines are usually not appropriate for beginners.

A rank beginner would be best with a full body routine. An intermediate or recreational bodybuilder could pick and choose the type of training schedule, but can’t go wrong with a 2 day split (such as our T.N.B. program – see links below. The body part splits are best for advanced bodybuilders with hypertrophy goals and cosmetic/ visual goals. So consider your training age when making a decision on your lifting schedule.

3. Body part splits may not be practical for some people’s lifestyle and schedule.

Most people don’t want to train 5 days a week, let alone 6, and some people would like to get as much done in just 3 days a week as possible. But many non-bodybuilders (recreational lifters) do want to gain muscle. On a program like my TNB workout, which is a 2 day upper – lower schedule (or a typical strength program), you can get excellent muscle development with a 3-4 days per week frequency.

3 Major factors in choosing your lifting schedule

There are other considerations which might influence your choice of training schedule and split routine, but in summary, these are the big three:

1. Goals (Are you training for strength, sports conditioning, or bodybuilding / aesthetic reasons?)
2. Training age (Are you a beginner or an advanced trainee?)
3. Practical considerations (What is your schedule like? What will fit into your lifestyle?)

Let me say it again – there is no single best split routine for building muscle. The ideal of the “One True Way” is a creation of the guru business.

On the other hand, you can weigh all the pros and cons of a body part split routine vs full body training and consider all these factors above. After doing that, one particular type of schedule might leap out at you as the one most logical choice. This should be very much based on your personal goals and your lifestyle at the time you choose a routine. The fact that a 4-day split is my choice has as much to do with the fact that I enjoy it the most as any other factor.

PS. The New Body (TNB)-28. Although I personally prefer body part split routines most of the time (the 4 day split I mentioned above and sometimes the 3-day split), for people who do not have competitive-level bodybuilding goals, the 2-Day split is the single most popular strength and muscle-building program. A complete 2-day split can be found in my Burn the Fat, Feed the Muscle book and it’s called TNB 28 (based on a  28-day cycle). The schedule looks like this (2 options):

The 2-day split, upper-lower option
Day 1: Upper Body (Chest, Back, Shoulders, Arms)
Day 2: Lower Body (Quads, Hams, Calves) and Abs

The 2-day split, push-pull option
Day 1: Chest, shoulders, triceps, abs
Day 2: Legs, Back, Biceps, calves

PPS. The New Body (TNB) TURBO: The even newer version, TNB TURBO uses the same 2-day split but adds superset training to maximize time efficiency. This kind of training can literally cut your workout time in half (easily at least by one-third) and is scientifically proven.
