PPL vs Upper/Lower: Which Split Builds More Muscle?

Push Pull Legs (PPL) and Upper/Lower are the two most popular intermediate hypertrophy splits. Both work. Both hit each muscle 2x/week. The differences are subtle but matter for your training. Here's the breakdown.

What they look like

Push Pull Legs (6 days)

• Day 1: Push (chest, shoulders, triceps)
• Day 2: Pull (back, biceps, rear delts)
• Day 3: Legs (quads, hamstrings, glutes, calves)
• Day 4: Push (variation A or B)
• Day 5: Pull (variation A or B)
• Day 6: Legs (variation A or B)

Upper / Lower (4 days)

• Day 1: Upper (strength bias — bench, row, OHP, weighted pullup at heavier loads)
• Day 2: Lower (squat, RDL, leg press)
• Day 3: Upper (volume bias — incline DB, cable rows, lateral raises at higher reps)
• Day 4: Lower (front squat, hip thrust, lunges)

Volume per session

PPL distributes volume across more sessions. A typical PPL day has 18-24 working sets focused on 2-3 muscle groups. An Upper day has 18-30 working sets across 5-6 muscles. Per-muscle volume per session ends up similar (12-15 sets) but Upper days are longer and more fatiguing in a single sitting.

Recovery

PPL has a built-in 72-hour gap between hitting the same muscle group (Push Mon, Push Thu = 72hrs of recovery for chest). Upper/Lower has 72-96 hours. Both are sufficient for hypertrophy recovery, but PPL's session-level fatigue is lower because you're concentrated on fewer muscles each day.

Time commitment

PPL is 6 days a week. Each session is 60-75 minutes. Upper/Lower is 4 days a week. Each session is 75-90 minutes. The total weekly training time is similar (~6-7 hours) but the distribution matters.

• PPL works if: You can train 5-6 days a week and prefer shorter, focused sessions
• Upper/Lower works if: You only have 3-4 training days available, or you prefer fewer but longer sessions

Strength vs hypertrophy bias

Upper/Lower is more conducive to strength work because you can dedicate one day to heavy compounds and another to volume. PPL traditionally has every session at moderate-to-high reps. If your goal is purely hypertrophy, both work. If you want concurrent strength + hypertrophy, Upper/Lower (PHUL-style) is the more elegant choice.

Frequency comparison

• PPL 6-day: 2× frequency per muscle (excellent for hypertrophy)
• PPL 5-day: Each muscle gets 1.5× frequency on average
• Upper/Lower 4-day: 2× frequency per muscle
• Upper/Lower 3-day: 1.5× frequency per muscle

If frequency is your priority, PPL 6-day or U/L 4-day are tied. Both deliver the optimal 2× per muscle.

Which to pick

Honest answer: it doesn't matter as much as people think. Both produce excellent hypertrophy when you progressively overload and run them consistently for 12+ weeks. Pick the one that fits your schedule and that you'll actually adhere to.

If you're undecided, default to PPL for maximum exercise variety and Upper/Lower for time efficiency.
