PHUL Workout Program: Power & Hypertrophy Upper Lower Split

PHUL combines heavy strength work with high-volume hypertrophy training in a 4-day upper/lower split for well-rounded muscle development.

PHUL — Power Hypertrophy Upper Lower — is a 4-day program that dedicates two days to heavy compound lifts (power) and two days to moderate-weight, higher-rep work (hypertrophy). It's the logical middle ground for lifters who want to get strong and look muscular without committing to 5-6 training days per week.

The PHUL Weekly Structure

Day 1 — Upper Power: Heavy bench press (3-5 reps), heavy rows (3-5 reps), overhead press and accessory work at moderate reps.

Day 2 — Lower Power: Heavy squats (3-5 reps), heavy deadlifts (3-5 reps), leg press and hamstring work at moderate reps.

Day 3 — Rest.

Day 4 — Upper Hypertrophy: Incline dumbbell press (8-12 reps), cable rows (8-12 reps), lateral raises, curls, and tricep work at 10-15 reps.

Day 5 — Lower Hypertrophy: Front squats or leg press (8-12 reps), Romanian deadlifts (8-12 reps), leg extensions, leg curls, and calf work at 10-15 reps.

Why PHUL Works So Well

Twice-weekly frequency: Every major muscle group gets trained twice — once heavy, once with volume. This frequency is optimal for most intermediate lifters.

Balanced development: Power days build strength that lets you use heavier weights on hypertrophy days. Hypertrophy days build muscle mass that supports strength on power days. The two feed each other.

Sustainable schedule: Four days per week is manageable for most lifestyles. You get three rest days to recover, which is enough for most natural lifters.

Who Is PHUL Best For?

PHUL suits intermediate lifters who have mastered basic movement patterns and want to optimize both strength and muscle growth. If you can bench your bodyweight, squat 1.25x bodyweight, and deadlift 1.5x bodyweight, you're ready for PHUL.

Customizing PHUL

The template is flexible. Swap exercises to match your available equipment, adjust rep ranges to emphasize your goals, or add an extra exercise for lagging muscle groups. The structure (power/hypertrophy split across upper/lower) matters more than the specific exercises.
