PHUL workout: the 4 day power hypertrophy upper lower plan

The PHUL workout (Power Hypertrophy Upper Lower) is a 4 day program by Brandon Campbell that trains the upper and lower body twice a week. Two days are power days with heavy compound lifts for 3 to 5 reps, and two are hypertrophy days with moderate weights for 8 to 12 reps or more. It mixes strength and muscle building in one week, which is why it is often called a powerbuilding program.

What is the PHUL workout?

Campbell published PHUL on Muscle and Strength as a way to train for strength and size at the same time without a complicated plan. The structure is an upper lower split: upper body, lower body, rest, upper body, lower body. What changes is the job of each day.

  • Power days (days 1 and 2): big barbell lifts first, 3 to 5 reps, heavy. This is where you build strength on the bench press, row, squat and deadlift.
  • Hypertrophy days (days 4 and 5): more exercises, more isolation work, 8 to 15 reps. This is where most of the muscle building volume sits.
  • Frequency: every muscle group is trained twice a week, once heavy and once for volume.

The Wednesday off splits the week into two blocks of back to back days. If your week does not fit, keep the order and spread it out, for example Monday, Tuesday, Thursday and Saturday. Avoid putting the lower hypertrophy day right before lower power. The workout planner helps you place the days around work or sport.

The full PHUL template: all 4 days

Sets and reps follow the original template. Where the program gives a range of sets, start at the low end and add the extra set later if you recover well.

Rest 2 to 5 minutes between sets of the big compound lifts on power days and 1 to 3 minutes on isolation work. On the hypertrophy days the rest can be shorter, but do not cut it so much that the weights drop every set.

How to progress on PHUL

PHUL uses rep ranges, so the simplest way to progress is double progression. Work in the range until you hit the top of it in every set with good form, then add weight and start again at the bottom. On the power lifts that means getting 5 reps on all sets before adding 2.5 kg (5 lb) to upper body lifts or 5 kg (10 lb) to the squat and deadlift. On the hypertrophy days, add reps first and weight second.

Stop most sets with a rep or two left. The heavy days only work if you show up fresh for them, and taking every hypertrophy set to failure makes that hard. It is progressive overload on two tracks: strength on days 1 and 2, volume on days 4 and 5. That is the opposite of the Mike Mentzer workout, where every work set goes to failure.

Choose starting weights from a recent hard set. The 1RM calculator turns, say, 80 kg (175 lb) for 6 reps into an estimated max, and a weight around 80 to 85 % of that estimate is a sensible first try for the 3 to 5 rep sets.

Plan a lighter week every 6 to 8 weeks or when the power lifts stall two weeks in a row. Keep the exercises, drop a set from everything and use about 10 % less weight.

Who PHUL suits

  • Good fit: lifters past the beginner stage who want both bigger numbers and more muscle.
  • Good fit: people who can train four days a week but not five or six.
  • Less ideal: true beginners. A simpler linear plan like GZCLP or a full body program adds weight faster in the first months.
  • Less ideal: anyone with long sessions as a problem. The upper days have seven exercises and can run past 75 minutes.

Short on time? Drop one arm exercise from each upper day and the second calf raise from day 5. The main lifts and rows are what carry the program.

PHUL vs PHAT vs push pull legs

PHUL compared
ProgramDays per weekStructureBest for
PHUL4Upper and lower, power and hypertrophy daysStrength and size on 4 days
PHAT (Layne Norton)5Upper and lower power days, then hypertrophy days by body partMore volume, more time in the gym
Push pull legs3 to 6Push, pull and leg daysFlexible, high volume on 6 days

PHUL vs PPL comes down to days. On four days, PHUL hits every muscle twice, while a push pull legs rotation on four days hits most muscles less often. See the 4 day split guide for more four day options side by side.

Build the four PHUL days in Gripp and log every set. On the 8 to 12 rep days it tells you what to go for next session: hit the top of the range in every set and the weight goes up. The estimated 1RM chart shows whether the power days are really moving your bench press, squat and deadlift.

Questions people ask

Is PHUL good for beginners?
It can work, but most beginners do better on a simpler program that adds weight every session. PHUL suits lifters with some months of training who want strength and muscle on four days a week.
How long should I run PHUL?
As long as you keep progressing. Many lifters run it for 8 to 12 weeks at a time, take a lighter week, then continue or rotate exercises on the hypertrophy days.
Is PHUL a powerbuilding program?
Yes. It combines heavy low rep work for strength with higher rep work for muscle size in the same week, which is what powerbuilding means.
Can I swap exercises in PHUL?
Keep the main barbell lifts on the power days. Accessory and hypertrophy exercises can be swapped for close matches, for example a machine chest press for the dumbbell fly or a Bulgarian split squat for the lunge.
What is the difference between PHUL and PHAT?
PHAT by Layne Norton runs five days with body part hypertrophy days. PHUL keeps the whole week in an upper lower format over four days, so it is shorter and easier to recover from.
How long does a PHUL workout take?
Usually 60 to 80 minutes, with the upper days the longest. Long rests on power days add time, so plan for it.
