PHUL is the 4-day split that tries to have it both ways — heavy strength work and higher-rep muscle-building in the same week. Here's how the two power days and two hypertrophy days are built, who it suits, and how to build it as a custom program in LiftHero.

In short: PHUL — Power Hypertrophy Upper Lower — is a 4-day-a-week upper/lower split that combines two heavy power days (upper and lower, lower reps on big compounds) with two hypertrophy days (upper and lower, higher reps, more volume and isolation). Each half of the body is trained twice a week — once for strength, once for size. It's aimed at intermediates who want both, and works well as a bridge between pure strength programs and bodybuilding-style training. LiftHero doesn't ship PHUL built in, but you can build it as a custom program with Hero and log every set.
PHUL stands for Power Hypertrophy Upper Lower. It's a four-day training week built on a simple idea: instead of choosing between getting strong and getting big, you split the week so you do both. Two sessions emphasize power — heavier weight, lower reps on the main compound lifts — and two sessions emphasize hypertrophy — moderate weight, higher reps, and more isolation volume.
Because the week is organized as an upper/lower split, every muscle group gets trained twice: once in a heavy, strength-focused style and once in a higher-volume, muscle-focused style. That twice-a-week frequency plus the mix of rep ranges is what makes PHUL a popular size-and-strength template for lifters past the beginner stage.
The whole program is four sessions built around two contrasting emphases. Here's the shape of it, step by step:
PHUL is two power days and two hypertrophy days, each split into upper and lower. Power days lean on heavy compounds in low rep ranges; hypertrophy days keep the same movement patterns but add reps, volume and isolation work.
| Day | Focus | Emphasis |
|---|---|---|
| Day 1 — Upper Power | Heavy bench, rows, overhead press, pulls | Strength · ~3–5 reps |
| Day 2 — Lower Power | Heavy squat, deadlift, leg press | Strength · ~3–5 reps |
| Day 3 — Upper Hypertrophy | Moderate presses, rows + isolation (chest, back, delts, arms) | Size · ~8–15 reps |
| Day 4 — Lower Hypertrophy | Moderate squat/leg work + isolation (quads, hams, calves) | Size · ~8–15 reps |
The power/hypertrophy contrast is the point: heavy low-rep work keeps you building strength on the big lifts, while the higher-rep days pile on the volume that drives muscle growth. Because it's an upper/lower structure, everything gets hit twice a week without any single session becoming overwhelming.
PHUL is generally aimed at the intermediate lifter — someone who has moved past a pure beginner linear-progression program and wants to develop both strength and size rather than picking one. It's a well-known bridge between strength-first training and bodybuilding-style volume.
| Great fit | Maybe look elsewhere |
|---|---|
| Intermediates who want strength and size together | True beginners who still progress every session |
| People who can commit to four training days a week | People limited to two or three days a week |
| Lifters bridging from strength work toward bodybuilding | Lifters wanting a single, narrow focus (pure powerlifting or pure physique) |
If you can only train three days a week, or you're still adding weight every session, a simpler template may fit better — see all programs or a standard upper/lower split. If you want a higher-frequency alternative, push/pull/legs is worth a look.
LiftHero doesn't ship PHUL as a built-in program — but you can build it as a custom program with the Hero subscription's program builder, then log every session against it. It records the full vocabulary of serious training — work sets, warm-ups, RPE and reps — and detects personal records automatically, so both your power lifts and your hypertrophy volume show up as trends you can actually see. It's free to start on iOS, with no routine caps and no interruptive ads.
Lay out the four PHUL sessions with the custom program builder in the optional Hero subscription, save them as reusable routines, and log every set free on iOS.

PHUL stands for Power Hypertrophy Upper Lower. It's a 4-day-a-week upper/lower split that combines two heavy, lower-rep power days with two higher-rep hypertrophy days, so you train each half of the body for both strength and size across the week.
Four days a week — typically Upper Power, Lower Power, Upper Hypertrophy and Lower Hypertrophy, arranged with rest days such as Monday, Tuesday, Thursday, Friday so each muscle group is trained twice a week.
Power days use heavier weight and lower reps, roughly 3 to 5, on big compound lifts to build strength. Hypertrophy days use moderate weight, higher reps of roughly 8 to 15, and more isolation exercises and volume to build size.
Yes — PHUL is generally aimed at intermediate lifters who have outgrown a pure beginner program and want both strength and muscle. It's a popular bridge between strength-focused training and bodybuilding-style volume.
A standard upper/lower split can use any rep scheme, but PHUL deliberately dedicates two of the four sessions to heavy power work and two to higher-rep hypertrophy work, so strength and size are trained as distinct emphases within the same week.
Yes — LiftHero doesn't ship PHUL as a built-in program, but you can build it as a custom program with the Hero subscription's program builder, save the four sessions as reusable routines, and log every set, rep and RPE so you can track strength and hypertrophy progress over time.
