PHUL stands for Power Hypertrophy Upper Lower. It is a 4-day split designed by Brandon Campbell that combines two strength-focused power days with two volume-focused hypertrophy days. The argument is that pure strength programmes leave size on the table, pure hypertrophy programmes leave strength on the table, and a hybrid programme can give you most of both. PHUL is one of the cleanest implementations of that idea, and it has earned a loyal following for good reason.

The structure is straightforward. Monday is Upper Power, Tuesday is Lower Power, Thursday is Upper Hypertrophy, Friday is Lower Hypertrophy. The Power days use heavier weights and lower rep ranges (3 to 5 reps) to drive strength. The Hypertrophy days use moderate weights and higher rep ranges (8 to 15 reps) to drive muscle growth. Each muscle is hit twice a week, once heavy and once with volume, which lines up with the modern hypertrophy research consensus.

The Full Template

Monday — Upper Power

Tuesday — Lower Power

Thursday — Upper Hypertrophy

Friday — Lower Hypertrophy

Wednesday and the weekend off. The total session count is 4, the time per session is roughly 60 to 80 minutes, and every major muscle group is trained twice across the week.

Why the Hybrid Structure Works

Pure strength programmes (5x5, 5/3/1, Sheiko) drive 1RM strength but produce limited hypertrophy because the rep ranges are too low and the volume too small for muscle growth. Pure hypertrophy programmes drive muscle growth but limit absolute strength gains because the rep ranges are too high to develop maximum force production. PHUL splits the difference by giving you both.

The Power days train the same nervous system pathways that pure strength programmes train: low reps, heavy weight, full rest periods, focus on bar speed. The Hypertrophy days train the same fibres that bodybuilding programmes train: moderate reps, moderate weight, shorter rest, focus on the muscle. Done well, the two stimuli reinforce each other rather than fight.

Coach's Take
PHUL is for the lifter who wants to be strong and look strong. If you only care about one of those, run a programme optimised for that goal. If you care about both, PHUL or a similar powerbuilding template is one of the cleanest structures available.

Who PHUL Suits

PHUL is most appropriate for intermediate lifters with at least 6 to 12 months of training experience. The Power days require enough technique on the main lifts (squat, bench, deadlift, overhead press) that a complete beginner is better served by a linear progression programme like StrongLifts or Starting Strength first.

It works well for:

It is less ideal for:

Progressive Overload on PHUL

On Power days, progress the main lifts by 2.5 kg per week (or 5 kg per fortnight if 2.5 kg starts to fail). Track every set, push for clean reps, and treat the Power day numbers as the strength benchmark for the programme.

On Hypertrophy days, progress by adding reps within the prescribed range first, then adding 2.5 kg when you hit the top of the range across all working sets. The progression is slower but more sustainable, since the loads are submaximal.

Take a deload every 4 to 6 weeks: drop the weight by 10 percent on Power days, halve the volume on Hypertrophy days, and treat it as scheduled recovery rather than a setback. The numbers will come back better than where you left them.

Common PHUL Mistakes

1. Treating the Hypertrophy days as light

The volume on PHUL Hypertrophy days is substantial. Lifters who treat them as 'easy' days because the weights are lighter are missing the point. The work has to be hard enough that the last 1 to 2 reps of each set are genuinely difficult. Lazy hypertrophy days produce no growth.

2. Adding extra exercises

PHUL has a defined exercise list. Adding three more chest exercises 'because you have time' destroys the recovery balance. Run the programme as written, then evaluate after 12 weeks.

3. Skipping the deadlift

The Power Lower day includes the deadlift. It is taxing. Some lifters quietly drop it. Substitute Romanian deadlifts or trap-bar deadlifts if necessary, but include a heavy hinge variant. Without it, posterior chain development lags.

4. Confusing this with a 6-day programme

PHUL is 4 days. Trying to run it 5 or 6 days a week by adding sessions almost always breaks recovery. If you want higher frequency, run a different programme rather than bolting extra days onto this one.
