What is the best workout split?

The best split is the one that fits the days you can train consistently and lets you recover. Full body is a strong default for 2–3 days, upper/lower for 4 days, and PPL for lifters who can reliably train 5–6 days.

Should beginners use push pull legs?

Usually not as a first choice. Beginners tend to get more repeat practice on the main lifts with a 2–3 day full body routine, or an upper/lower split when they have four dependable training days.

Can I change my workout split?

Yes. Change when your available training days, recovery, or desired volume changes for more than a few weeks. Keep the exercises and progression simple during the switch.

Can I do a full body workout 4 days a week?

While possible with careful fatigue management, four consecutive or tightly clustered full-body days often lead to cumulative joint fatigue. An upper/lower split is generally more sustainable when training four days per week.

What workout split builds the most muscle?

No single split holds an inherent hypertrophy advantage. Muscle growth depends on total weekly volume, intensity of effort, and recovery. Choose the split that allows you to complete your target volume consistently with good recovery.

Split	Frequency	Recovery	Session length	Best for	Tradeoff
Full Body	2–3 days/week	High	45–75 minutes	Most efficient; frequent practice	Less room for many isolation exercises
Upper/Lower	4 days/week	Moderate	60–80 minutes	Balanced twice-weekly muscle work	Needs four consistent days
Push Pull Legs	5–6 days/week	Moderate	45–75 minutes	More room for volume and exercise variety	Missed days can unbalance the week
Bro Split	5 days/week	High between muscles	60–90 minutes	Dedicated specialization sessions	Usually only one direct exposure per muscle

Experience: Advanced. Dedicated specialization sessions.

How to compare splits properly

Splits are frequently compared on frequency alone, which is misleading. A fair comparison holds weekly volume roughly constant and asks how the split distributes that volume across the week. Use these four criteria in order:

Attendance you can protect. A split you complete three days a week beats one you plan for six days but complete half of. Count the training windows you can realistically keep for the next three months, not your best-case week.
Matched weekly volume. Compare splits only when weekly hard sets per muscle group are similar. A 6-day PPL routine is not automatically superior to a 4-day upper/lower routine if both deliver the same 12–16 weekly sets per muscle—the difference is how that volume is packaged into sessions.
Per-session set ceiling. Most lifters get the majority of a session's hypertrophy stimulus from the first 6–10 hard sets for a muscle group; sets beyond that add fatigue faster than they add stimulus. Splits that keep single-session sets under that ceiling (upper/lower, PPL) generally out-perform splits that stack 15+ sets into one sitting (bro split) for the same weekly total.
Recovery window between repeats. Muscle protein synthesis stays elevated for roughly 24–48 hours after a session. Splits that revisit a muscle group inside that window (twice-weekly frequency) use the training stimulus more consistently than splits that leave 6–7 days between exposures.

Run every comparison on this site through the same four checks, which is why the interactive selector above asks about days, experience, and priority instead of naming a single "best" split.

Match your constraint to a split

Your situation	Start here	Why
You can protect 2–3 days most weeks	Full Body	Every session covers the major patterns, so a missed day never leaves a muscle group untouched for a full week.
You have exactly 4 reliable days	Upper/Lower	Splitting by body region gives each half two focused sessions without needing a fifth or sixth day.
You can train 5–6 days and want more volume	Push Pull Legs	Grouping by movement pattern spreads more weekly sets across shorter, more targeted sessions.
You're advanced and want single-muscle specialization	Bro Split	One dedicated session per muscle allows very high per-session volume for lifters who recover well.
Your schedule changes week to week	Full Body or a 3-day Upper/Lower/Full rotation	Both tolerate an irregular calendar better than a split that assumes a fixed weekday pattern.
