PHUL vs PPL: Which Split Fits Your Schedule?

PHUL — Power Hypertrophy Upper Lower — is a four-day split with two power-focused days and two hypertrophy-focused days. Monday and Tuesday are power upper and power lower, with main lifts in the 3-5 rep range. Thursday and Friday are hypertrophy upper and hypertrophy lower, with the same movements trained in the 8-15 rep range. Each muscle group is trained twice per week, once for strength and once for size.

PPL — Push Pull Legs — groups by movement function. Push day: chest, shoulders, triceps. Pull day: back, biceps, rear delts. Legs day: quads, hamstrings, glutes, calves. PPL can run three, four, five, or six days a week. The six-day version trains each group twice in a six-day rotation; the three-day version trains each once per week.

For purely training outcomes, both work. PHUL emphasizes strength carryover more by dedicating separate days to heavy compound work. PPL emphasizes volume per muscle group more by giving each function its own full session. A six-day PPL accumulates more weekly volume per muscle than a four-day PHUL; a PHUL has more bilateral heavy loading than a PPL of comparable frequency.

The schedule question is where the comparison gets practical. PHUL is four days. PPL at six days is almost double the gym commitment. If your schedule is stable — same four days every week, year-round — PHUL's structure of paired power-and-hypertrophy days gives every muscle group a predictable stimulus. Missing a session once a month is manageable; the following power or hypertrophy day still covers the basics.

If your schedule varies, PPL is usually more forgiving — but only at lower frequencies. A three-day PPL rotated through the week can absorb missed days without losing coverage. A six-day PPL is the opposite: miss two days and a full muscle group goes untrained for ten days. The high-frequency version assumes you actually hit the high frequency.

For most intermediate lifters managing real jobs and real life, the honest answer is usually a four-day split — whether PHUL or a four-day PPL variant. The evidence that six days produces dramatically more hypertrophy than four is not strong enough to justify the adherence risk when the extra days are the ones most likely to be skipped. Build the four-day habit first; add days only if the extra sessions consistently happen.

LiftProof tracks which sessions you actually complete versus which you plan. That gap is usually where the real programming decision lives. A program you execute at 90% adherence beats a program you execute at 50% adherence, every single time.
