PHUL

What is PHUL?

PHUL stands for Power Hypertrophy Upper Lower. It is a 4-day training split that combines two strength-focused power days (upper and lower) with two hypertrophy-focused volume days (upper and lower). The structure trains every muscle group twice per week, once with heavy compound work for strength and once with moderate-rep work for hypertrophy. The combined approach produces both strength and size gains, making it one of the most popular powerbuilding templates available.

Who is PHUL for?

PHUL suits intermediate lifters who want to build both strength and visible muscle simultaneously. Beginners typically benefit from simpler full-body or linear-progression programs first. Advanced lifters may need higher volume or more specialized programming than PHUL provides. The trainee with 1 to 4 years of consistent training, who wants the strongest combined strength-and-size outcome from a 4-day program, fits the PHUL target user.

How is the week structured?

Day 1 (Upper Power): heavy bench press, heavy row, accessory pressing, accessory pulling, biceps and triceps. Day 2 (Lower Power): heavy squat, heavy deadlift, accessory leg work. Day 3 rest. Day 4 (Upper Hypertrophy): moderate-rep incline pressing, moderate-rep rowing, lateral raises, isolation arms. Day 5 (Lower Hypertrophy): moderate-rep front squats, moderate-rep Romanian deadlifts, leg curls, leg extensions, calves. Days 6 and 7 rest. The structure provides each muscle group with one heavy day and one moderate-rep day weekly.

Power day structure

Power days emphasize compound lifts at heavy loads. Upper power: bench press 3 to 4 sets of 3 to 5 reps at 80 to 90 percent of 1RM, heavy row 3 to 4 sets of 3 to 5 reps, plus 2 to 3 accessory exercises at 6 to 10 reps. Lower power: squat 3 to 4 sets of 3 to 5 reps at 80 to 90 percent of 1RM, deadlift 3 sets of 3 to 5 reps, plus accessory leg work at 6 to 10 reps. The power days produce the strength stimulus.

Hypertrophy day structure

Hypertrophy days emphasize moderate-rep volume work. Upper hypertrophy: incline pressing 4 sets of 8 to 12 reps, rowing variation 4 sets of 8 to 12 reps, lateral raises 3 to 4 sets of 12 to 15 reps, biceps and triceps 3 sets each of 10 to 15 reps. Lower hypertrophy: squat or front squat variation 4 sets of 8 to 12 reps, Romanian deadlift 3 to 4 sets of 8 to 12 reps, leg curls 3 to 4 sets of 12 to 15 reps, leg extensions and calf work to finish. The hypertrophy days produce the muscle-growth stimulus.

How do you progress on PHUL?

Progress power lifts through linear or weekly progression on the heavy compound work. Add 2.5 kilograms to upper power lifts and 5 kilograms to lower power lifts when working sets are completed cleanly. Progress hypertrophy lifts through double progression: accumulate reps at fixed weight until top of range, then add weight. Most trainees can sustain weekly progression for 8 to 16 weeks before requiring deload weeks every 6 to 8 weeks.

What are the strengths of PHUL?

The combined strength and hypertrophy approach is its primary advantage. Trainees on PHUL typically build noticeable strength on the main lifts and noticeable muscle mass simultaneously, which is rarer than either outcome alone. The 4-day structure fits most working adults' schedules. The clear power-vs-hypertrophy day distinction provides programming clarity that more complex programs lack. The lift selection is conventional and accessible.

What are the limitations of PHUL?

The volume is moderate; trainees with high recovery capacity and time may produce faster gains on higher-volume programs (5 or 6 day splits). The structure requires consistent 4-day adherence; missing days disrupts the heavy-vs-moderate balance. Some trainees prefer either pure strength or pure hypertrophy programming and find the dual focus diluting. The program does not specifically optimize for any single goal.

Frequently asked questions

Is PHUL good for beginners?

Most beginners produce better results on simpler programs first. The 4-day structure and the heavy-vs-moderate distinction add complexity that beginners do not need; they progress fast on full-body 3-day programs through linear progression alone. After 6 to 12 months on a beginner program, transitioning to PHUL becomes appropriate.

How does PHUL compare to PHAT?

Both are powerbuilding programs. PHAT (Power Hypertrophy Adaptive Training) uses 5 days per week with two power days and three hypertrophy days; PHUL uses 4 days per week with two of each. PHAT has higher weekly volume and produces faster hypertrophy at the cost of higher recovery demand. PHUL fits more schedules and is more sustainable for working adults; PHAT is the higher-yield option for trainees with the time and recovery for it.

Should I do cardio on PHUL?

Two to three zone-2 cardio sessions per week of 30 to 45 minutes each fit the program without significant interference. Schedule them on rest days or after the lifting sessions. Avoid heavy cardio in the 24 hours before a lower-body power day; the leg recovery affects squat and deadlift output significantly.

How long should you run PHUL?

3 to 6 months at a time before considering changes. The program produces continued progress for most trainees across this duration. After that, periodizing into a more specialized strength or hypertrophy block for 8 to 12 weeks before returning to PHUL maintains long-term progress without burnout.
