The split you choose determines your results as much as the exercises themselves. But most people overthink it.
There are four main training splits: Push/Pull/Legs (PPL), Upper/Lower, Full Body, and Bro Split. Each has distinct advantages and trade-offs.
The research shows frequency matters (training a muscle 2x per week beats 1x per week), but the split that lets you sustain consistency beats the "optimal" split you'll abandon.
The Four Main Splits
Push/Pull/Legs (PPL)
Structure: Six training days per week, each dedicated to one movement pattern.
- Day 1: Push (chest, shoulders, triceps)
- Day 2: Pull (back, biceps)
- Day 3: Legs
- Day 4: Push (repeat)
- Day 5: Pull (repeat)
- Day 6: Legs (repeat)
Frequency: Each muscle is trained twice per week.
Advantages:
- High training frequency (2x per week per muscle). Research supports this for hypertrophy.
- Clear organisation. Each day is focused, which simplifies programming.
- High volume per session (each session trains one pattern fully).
- Scales well from beginner to advanced.
Disadvantages:
- Requires six training days per week. Not sustainable for many lifters with jobs and life commitments.
- High recovery demand. Six hard days is significant systemic stress.
- Not beginner-friendly in terms of volume (each session is substantial).
Best for: Advanced lifters, people who prioritise training over other activities, anyone with recovery capacity and time to commit.
Reality check: Many people claim to do PPL but miss days (life happens). Six days consistently is hard.
Upper/Lower
Structure: Four training days per week, alternating upper and lower body.
- Day 1: Upper (back, chest, shoulders, arms)
- Day 2: Lower (quads, hamstrings, glutes, calves)
- Day 3: Rest
- Day 4: Upper (repeat)
- Day 5: Lower (repeat)
Frequency: Each muscle is trained twice per week (e.g., back twice per week, quads twice per week).
Advantages:
- Optimal frequency (2x per week per muscle) with minimal days per week (four).
- Manageable volume per session (split upper/lower keeps each session sustainable).
- Highly sustainable. Four training days is realistic for most lifters.
- Excellent progression. Split clearly shows what's trained, easy to add volume over time.
- Proven effective for intermediate to advanced lifters.
Disadvantages:
- Less organised than PPL in some ways (multiple muscle groups per session). Requires planning to balance chest, back, shoulders, and arms.
- Requires at least 48 hours between lower sessions (legs are demanding).
- Not ideal for absolute beginners (still substantial volume per session).
Best for: Intermediate and advanced lifters with realistic training schedules, anyone wanting high frequency without six-day commitment.
Reality check: This is the sweet spot. Most people who train consistently gravitate here.
Full Body
Structure: Three training days per week, training entire body each session.
- Day 1: Full body (squats, bench, rows, arms, accessories)
- Day 2: Rest
- Day 3: Full body (similar structure)
- Day 4: Rest
- Day 5: Full body
- Day 6-7: Rest
Frequency: Each muscle trained 3x per week (minimum 48 hours between sessions).
Advantages:
- Highest frequency (3x per week per muscle).
- Minimal time requirement (three days per week).
- Beginner-friendly. Low complexity, simple progression model.
- Excellent for busy people or those new to lifting.
- Very sustainable (three days per week is easy to commit to).
Disadvantages:
- Lower volume per session (you can't train chest hard, back hard, legs hard and do it all in one session).
- Total weekly volume is often lower than PPL or Upper/Lower because session volume is limited.
- Not ideal for advanced lifters (volume ceiling is lower).
- Recovery can be tricky. Three hard days in five days is substantial.
Best for: Beginners, busy lifters, anyone preferring simplicity over optimisation.
Reality check: Underrated for actual results. Consistency beats perfect programming.
Bro Split (Body Part)
Structure: Five training days per week, one body part per day.
- Day 1: Chest
- Day 2: Back
- Day 3: Shoulders
- Day 4: Arms
- Day 5: Legs
- Day 6-7: Rest
Frequency: Each muscle trained once per week.
Advantages:
- Simple to understand and plan.
- High volume per session per muscle (you focus entirely on one).
- Good for ego-lifting (lift heavy on your "day").
- Easy to adjust programming (lagging muscle? Add more volume on that day).
Disadvantages:
- Lowest training frequency (once per week per muscle). Research shows 2x per week is superior.
- Requires five training days per week (or four with two muscles per day, which defeats the purpose).
- Not beginner-friendly (five hard days is substantial).
- Recovery demand is high.
- Volume per muscle is often lower long-term (one session per week limits progression).
Best for: Advanced lifters with specific lagging muscles, people who enjoy maximum session focus.
Reality check: Not optimal for hypertrophy based on frequency research. Still works if you eat and recover well, but leaves gains on the table.
The Frequency Research
Brad Schoenfeld's meta-analyses show this: training a muscle 2x per week produces more hypertrophy than 1x per week, assuming total volume is roughly equal.
This matters for PPL, Upper/Lower, and Full Body (all hit 2-3x per week). It doesn't support Bro Split (1x per week).
The mechanism: more frequent stimulus allows better recovery-to-stimulus ratio and prevents the "detraining effect" (muscle protein synthesis drops after 48-72 hours without stimulus).
The caveat: if total volume is matched (Bro Split with massive volume per session vs Upper/Lower with moderate volume), the difference shrinks. But in practice, weekly volume is often lower on Bro Split because session volume has limits.
Choosing Your Split
Beginner (0-1 year training): Full Body, 3x per week. Simple, sustainable, excellent results. Once you've mastered form and built initial strength, consider progressing to Upper/Lower.
Intermediate (1-3 years training): Upper/Lower, 4x per week. Optimal frequency with manageable volume. This is where most lifters should live. Excellent progression model.
Advanced (3+ years training, serious about training): PPL, 6x per week. Only if you can commit to six days consistently. Otherwise, Upper/Lower remains optimal.
Time constraint (can only train 3x per week): Full Body. Make it work. Total volume matters more than split perfection.
Genetic responders, excellent recovery, want maximum volume: PPL, 6x per week. Takes advantage of superior recovery capacity.
Already adapted to lower frequency, don't have 4+ days: Bro Split, 5x per week. It works despite lower frequency. It's not optimal, but consistency beats optimal-but-missing.
Split Selection Flowchart
Can you train 6 days per week consistently? → Yes → PPL Can you train 4 days per week consistently? → Yes → Upper/Lower Can you only train 3 days per week? → Yes → Full Body Can you train 5 days per week consistently? → Yes → Upper/Lower (prioritise) or Bro Split (if you must) You're a beginner? → Full Body first, then Upper/Lower after 6-12 months
Realistic Assessment
Most lifters don't train optimally because life happens. Missed sessions, inconsistent schedule, fatigue. The best split is the one you'll actually do.
A mediocre PPL performed consistently beats optimal Upper/Lower performed intermittently.
A simple Full Body done three times per week beats a complex Upper/Lower attempted five times but only achieved three times.
Plan your split around your realistic capacity, not your ideal capacity.
Practical Examples
Full Body Example (Beginner, 3x per week):
Day 1 & 3 & 5:
- Squat: 3 x 8
- Barbell Row: 3 x 8
- Dumbbell Bench: 3 x 8
- Assisted Pullup: 3 x 6-8
- Dumbbell Shoulder Press: 2 x 8
- Barbell Curl: 2 x 10
Simple, balanced, effective.
Upper/Lower Example (Intermediate, 4x per week):
Upper Day 1:
- Barbell Bench: 4 x 6-8
- Barbell Row: 4 x 6-8

- Romanian Deadlift: 3 x 8
- Leg Press: 3 x 10-12
- Leg Curl: 3 x 12
- Calf Raise: 3 x 10-15
Repeat upper and lower across the week.
PPL Example (Advanced, 6x per week):
Push Day:
- Overhead Press: 4 x 6-8
- Incline Barbell Bench: 4 x 6-8
- Lateral Raises: 3 x 12-15
- Tricep Pushdown: 3 x 12-15
Pull Day:
- Weighted Pullup: 4 x 6-8
- Barbell Row: 4 x 6-8
- Lat Pulldown: 3 x 10-12
- Barbell Curl: 3 x 8-10
Leg Day:
- Barbell Squat: 4 x 6-8
- Romanian Deadlift: 3 x 8
- Leg Extension: 3 x 12-15
- Leg Curl: 3 x 12-15
Repeat all three days twice per week.
The Bottom Line
Frequency matters. Training a muscle 2x per week beats 1x per week.
PPL, Upper/Lower, and Full Body all hit 2-3x per week frequency (superior). Bro Split hits 1x per week (not ideal, but works if volume is massive and recovery is perfect).
Choose based on your realistic training capacity:
- Beginner, limited time: Full Body
- Intermediate, 4 days available: Upper/Lower
- Advanced, 6 days available: PPL
- Time-constrained: Full Body
The split isn't magic. Consistency, progressive overload, and nutrition matter more. Pick one and stick to it for 12+ weeks before switching.
