The best workout split is the one that matches how many days you can actually train and how advanced you are, not whatever split is trending on Instagram this month. Here’s the quick version before we break down each option below:
- 3 days a week: full body wins.
- 4 days a week: upper/lower is hard to beat.
- 5 to 6 days a week: push/pull/legs lets you train each muscle with more focus per session.
- 5 to 6 days, one muscle per day: bro splits work too, but mostly for people who are already advanced and just enjoy training that way.
That’s the honest answer. Anyone telling you there’s one split that beats all the others for every lifter is selling something. We’ve coached people through all four structures at FitStrot, and the split rarely makes or breaks progress. Consistency, total weekly volume, and whether you actually enjoy showing up do that.
What Actually Determines Which Split Is Best For You
Before picking a split, answer two questions honestly. How many days a week can you realistically train, not in a perfect world, but on an average busy week? And how experienced are you with lifting?
These two answers narrow the field fast. A beginner with 3 days available has no business running a 6-day PPL split. An advanced lifter training 6 days a week will get bored and undertrained on a basic full body routine. Match the split to your reality first. Everything else is secondary.
Full Body Split (3 Days a Week)
Full body training means hitting most major muscle groups in a single session, three times a week with rest days in between (think Monday, Wednesday, Friday). Each muscle group gets trained three times weekly, just with fewer total sets per session compared to a split routine.
This is where we start almost every new client, and for good reason. Research on training frequency, including the well-known meta-analysis by Schoenfeld and colleagues, found that training a muscle group at least twice a week produces better hypertrophy outcomes than training it once a week when total volume is equal. Full body training naturally builds in that frequency without you having to think about it.
It’s also the most time-efficient option if your week is unpredictable. Miss a session and you haven’t lost an entire muscle group for the week, because you’ll hit it again in two days anyway.
Upper/Lower Split (4 Days a Week)
Upper/lower splits alternate between upper body days and lower body days, usually two of each per week (Monday upper, Tuesday lower, Thursday upper, Friday lower, for example). Each muscle group still gets trained twice weekly, which keeps you in that frequency sweet spot the research points to, but now you have more time per session to add volume and accessory work.
This is our go-to recommendation for anyone with 4 solid training days and at least a few months of consistent lifting behind them. It hits a practical middle ground: more focused sessions than full body, without the 5-6 day commitment that push/pull/legs demands.
If you’re specifically training to bulk, we’ve laid out a complete 4-day upper/lower split with exact sets and reps that goes deeper into programming this structure for size.
Push/Pull/Legs (5 to 6 Days a Week)
PPL splits divide training into pushing movements (chest, shoulders, triceps), pulling movements (back, biceps), and legs, run either once through per week on 3 days or twice through on 6 days. The 6-day version is the one most lifters mean when they talk about “running PPL.”
This is genuinely a strong option, but only if you can commit to the volume. Running PPL twice weekly on 6 days gives each muscle group two dedicated, focused sessions, which again lines up with what the frequency research supports. The catch is recovery. Six days of training with limited rest between muscle groups means your sleep, nutrition, and stress management need to be dialed in, or you’ll dig a hole you can’t recover from.
We see this a lot with clients who jump straight into 6-day PPL because a fitness influencer runs it. They’re not advanced enough yet to recover from that volume, and within a few weeks they’re grinding through sessions instead of progressing in them. PPL is best earned, not started with.
Bro Split (5 to 6 Days, One Muscle Group Per Day)
The bro split dedicates each training day to a single muscle group: chest day, back day, shoulder day, arm day, leg day. It’s the oldest structure in bodybuilding and still popular in commercial gyms.
The problem is frequency. Training a muscle group once a week falls below what most hypertrophy research supports for natural lifters, since you’re relying on cramming a huge amount of volume into one session rather than spreading it across two visits. It can still work, particularly for advanced bodybuilders who can handle very high per-session volume and have the recovery capacity to back it up. For most people building a fitness base, it’s not the most efficient use of training days.
Comparison Table: Which Split Fits Your Situation
| Split | Days Per Week | Best For | Frequency Per Muscle |
|---|---|---|---|
| Full Body | 3 | Beginners, busy schedules, time-crunched lifters | 3x/week |
| Upper/Lower | 4 | Intermediate lifters, general fitness and bulking goals | 2x/week |
| Push/Pull/Legs | 5-6 | Intermediate to advanced lifters who can recover from high volume | 1-2x/week |
| Bro Split | 5-6 | Advanced bodybuilders, high per-session volume tolerance | 1x/week |
Does the Split Actually Matter More Than Volume?
Not really, and this is the part most articles gloss over. A well-known study comparing split routines to full body training in trained lifters found no significant difference in strength or hypertrophy outcomes when total weekly volume was matched between groups. More recent reviews pooling dozens of studies back this up: total weekly sets per muscle group is the strongest predictor of growth, not how those sets get divided across the week.
So why does the split matter at all? Because it determines whether you’ll actually hit that volume consistently. A split you enjoy and can stick to for months beats a “scientifically optimal” one you abandon after three weeks. That’s the whole point of choosing based on your days and experience level instead of chasing whatever split looks best on paper.
How Should Beginners Choose a Split?
Start with full body, 3 days a week, for at least your first few months. You’re still learning movement patterns and building work capacity, and full body training gives you the most practice reps on your major lifts without overwhelming your recovery. Once 3 days feels easy and you’re consistently adding weight or reps, that’s your signal to consider a 4th day and move to upper/lower.
We built a broader walkthrough of this progression in our best workout routine guide, which covers how to structure a week beyond just picking a split.
How Should Intermediate and Advanced Lifters Choose a Split?
If you’ve been training consistently for a year or more and have 4-6 days available, upper/lower or push/pull/legs will serve you better than full body. You’ve built enough work capacity to handle more focused, higher-volume sessions, and splitting your week lets you push harder on fewer muscle groups per day instead of spreading effort thin across everything.
Advanced lifters chasing specific aesthetic goals sometimes layer in bro split days for lagging muscle groups, but that’s a refinement, not a starting point. Get the fundamentals of upper/lower or PPL working first.
Building Your Weekly Schedule Around Your Split
Picking the split is step one. Fitting it into an actual week with work, sleep, and life around it is step two, and it’s where most people trip up. A 6-day PPL split looks great in theory and falls apart the first week someone has a late work meeting or a sick kid. Be realistic about the days you can protect before committing to a structure that needs all of them. Our weekly workout schedule guide walks through building a week that actually survives contact with real life.
If you’re not sure which split fits your specific situation, or you want a program built around your actual schedule instead of a template pulled off the internet, that’s exactly what our 1-on-1 personal training is for. Yash and the coaching team build a 12-week plan around your days, your experience level, and your goals, then adjust it as you progress instead of leaving you to guess.

Frequently Asked Questions
What is the best workout split?
There isn’t one universal best split. The right choice depends on your training days and experience level: full body for 3 days a week, upper/lower for 4 days, and push/pull/legs for 5 to 6 days. Research shows total weekly volume matters more than the split itself, so pick the structure you can realistically stick to long-term.
How do you do the best workout split?
Start by counting your realistic weekly training days, then match that number to a split (3 days: full body, 4 days: upper/lower, 5-6 days: PPL). Train each muscle group at least twice weekly where possible, track your sets and progression, and stick with the structure for at least 8-12 weeks before switching.
What are the benefits of choosing the right workout split?
The right split makes it easier to hit enough weekly training frequency per muscle group, fits realistically into your schedule so you actually stay consistent, and lets you manage fatigue and recovery better than randomly structured training. Consistency over months is what drives results, and the right split supports that consistency.
How many days a week should beginners train?
Most beginners do best with 3 days a week using a full body split. It’s enough frequency to build strength and muscle quickly while leaving enough recovery time for someone whose body isn’t yet adapted to regular resistance training. You can add a 4th day once 3 days starts feeling manageable.
Can you switch workout splits without losing progress?
Yes, switching splits doesn’t reset your progress as long as total weekly volume and training frequency stay similar. Many lifters move from full body to upper/lower to PPL as they add training days and experience over time. Just give any new split several weeks before judging whether it’s working.
