Best Workout Split: Full Body vs PPL vs Upper Lower

What a Workout Split Actually Is

A split is just how you distribute your weekly training across sessions. Three full body sessions a week trains every muscle 3x. A 4-day upper/lower trains every muscle 2x. A 6-day push/pull/legs trains every muscle 2x.

The math that matters is weekly frequency per muscle (how many times each muscle gets stimulus per week) and weekly volume per muscle (how many hard sets it gets total). See training frequency and how many sets per muscle per week.

Full Body (3 Days a Week)

Schedule: Monday, Wednesday, Friday.

Each session: every major muscle group with 1 to 2 exercises.

Frequency per muscle: 3x per week.

Best for:

• Beginners in their first 12 months
• Anyone with 3 to 4 hours total to train per week
• People rebuilding after a long break
• Anyone who values flexibility (missing one session is not a disaster)

Sample week:

Full body is the highest frequency split for the time budget. For new lifters, this is almost always the right answer for the first 12 months. See build a routine for an example, or the best beginner lifting programs for ready-made routines (StrongLifts, GZCLP, and others) that already run on this split.

Upper / Lower (4 Days a Week)

Schedule: Mon (upper), Tue (lower), Thu (upper), Fri (lower).

Each session: half the body, with more volume per muscle per session.

Frequency per muscle: 2x per week.

Best for:

• Early intermediates (1 to 3 years training)
• People with 4 to 6 hours to train per week
• Lifters who want more weekly volume per muscle than 3-day full body allows
• Anyone whose schedule is consistent enough to commit to 4 days

Sample week:

Upper/lower is the most popular split for the intermediate range because it stacks well with full-time work, lets you progress more lifts than full body, and still hits each muscle twice a week.

Push / Pull / Legs (6 Days a Week or 3 Days a Week)

Schedule: push, pull, legs, repeat. Either 6 days a week (each muscle 2x) or 3 days a week (each muscle 1x).

Each session: push muscles (chest, shoulders, triceps), pull muscles (back, biceps, rear delts), or legs.

Frequency per muscle: 2x per week (6-day version) or 1x (3-day version).

Best for:

• Intermediate to advanced lifters (3+ years)
• People with 5 to 8 hours per week to train
• Lifters who want long sessions per muscle group
• Anyone bored of full body or upper/lower

Sample week (6-day):

The 3-day PPL version is a popular beginner split too, but it hits each muscle only once a week. For most beginners, full body 3x outperforms PPL 3x. See training frequency for why.

If PPL is your pick, run a proven template instead of improvising: the r/Fitness PPL program for barbell access, or the dumbbell PPL program for home and hotel gyms.

Upper Lower vs Push Pull Legs: The Direct Comparison

This is the most common split decision, so here it is head to head. When weekly volume and frequency per muscle are matched, both build muscle the same. The real differences are scheduling:

The decision rule:

• You can train 4 days a week: upper/lower. PPL at 4 days leaves muscles waiting too long between hits.
• You can train 6 days, every week, reliably: either works. Pick PPL if you prefer short focused sessions, upper/lower stretched to 6 days if you prefer variety inside each session.
• You can train 3 days: neither. Full body beats both at that frequency.

If your week is unpredictable, upper/lower is the safer default: a missed PPL day on the 6-day version pushes the whole rotation, while a missed upper/lower day just repeats in the next slot.

Body Part Split / "Bro Split" (5 Days a Week)

Schedule: chest day, back day, leg day, shoulder day, arm day.

Each session: one muscle group, 15 to 25 sets total.

Frequency per muscle: 1x per week.

Best for:

• Advanced lifters with very high training age
• Lifters who genuinely enjoy long, focused sessions
• Lifters who can tolerate one muscle being savaged once a week

Body part splits are popular and still produce results in advanced lifters, but research and modern coaching favor higher frequency per muscle (2x per week minimum). For beginners and intermediates, a body part split usually underperforms full body or upper/lower.

How to Pick Your Split

Pick by available days first, then by training age.

Adjust down if recovery, sleep, or nutrition is not airtight. A 6-day split on bad sleep is worse than a 3-day split on good sleep. See daily habits that build muscle and consistency beats intensity.

How Long to Stay on a Split

At least 12 weeks before changing. Most plateaus are not about the split, they are about volume, intensity, or recovery. See how to break through a gym plateau.

The lifters with the cleanest physiques tend to stay on a split for 6 to 18 months at a time. Constant program-hopping is the number 9 beginner mistake for a reason.
