PHUL 4-day split: routine, exercises, and weekly schedule

A 4-day PHUL split gives you four workouts a week: two upper, two lower, but with a twist. One upper and one lower day are for power (heavy, low reps) and the other two for hypertrophy (moderate weight, higher reps). It builds strength and size without burnout. Most lifters who switched to PHUL saw their deadlift go up without losing muscle. Here's how to set it up.

The 4-day PHUL split, Power Hypertrophy Upper Lower, is a middle ground for lifters who want both strength and size without spending six days in the gym. You hit upper and lower body twice a week, alternating between heavy, low-rep work on power days and moderate reps for hypertrophy. The catch: managing fatigue across two upper body sessions in one week is harder than it sounds. A 2017 meta-analysis found that training each muscle group twice per week produced slightly greater hypertrophy than once per week, but only if you keep volume and load balanced. That's where most people trip up, too much intensity on power day, not enough recovery before hypertrophy day. Dorsi can help you adjust that balance in real time, without second-guessing your next set.

Practical Playbook

  1. How do I structure upper and lower days?

    PHUL splits into two power days and two hypertrophy days. Power upper hits bench press, overhead press, rows at 3-5 reps. Power lower: squat, deadlift at lower reps. Hypertrophy upper uses 8-12 reps for incline press, lateral raises, curls. Lower follows suit with leg press, lunges, leg curls. Stick to this alternating pattern across the week.

  2. Pick compound lifts for power days

    Your power days live or die by the big compounds. For upper, bench press and overhead press are non-negotiable. Lower power means squats and deadlifts. Don't waste energy on isolation here. Keep accessories to one or two movements max. This is where you build strength, not pump.

  3. Balance volume on hypertrophy days

    Hypertrophy days need more sets but controlled. Upper: add incline press, DB flyes, lateral raises, curls, pushdowns, aim for 15-20 total sets. Lower: leg press, lunges, leg extensions, leg curls. Each set at 8-12 reps. Going beyond 20 sets per session? You're accumulating junk volume, not growth.

  4. When should I deload?

    Push PHUL for 4-6 weeks straight, then deload. Drop set volume by 40-50% but keep the bar weight near your normal working loads. You need the stimulus, not the fatigue. Without this built-in recovery, your CNS burns out and progression stalls. Deload week is not a vacation; it's a reset.

Common Mistakes

  • Mistake
    Treating PHUL like a standard bodybuilding split by using the same rep ranges every day.
    Why
    PHUL alternates power and hypertrophy days. Running everything at 8-12 reps means you never develop the strength component, and the program stalls fast.
    Fix
    On upper and lower power days, keep reps at 3-5 with heavy weight. On hypertrophy days, stay in the 8-12 rep range. Mark each session so you know which day it is.
  • Mistake
    Never deloading because you don't think you need a break from four days a week.
    Why
    PHUL accumulates fatigue from both heavy loads and high volume. Without a deload every 6-8 weeks, CNS burnout and joint pain derail progress.
    Fix
    Schedule a deload week after 6 weeks of training. Drop volume by half or reduce weights by 10-20% for that week before resuming.
  • Mistake
    Adding extra cardio or HIIT sessions on top of all four lifting days.
    Why
    PHUL already includes two demanding power days. Extra conditioning on lower power day, for example, can crush recovery and leave you under-recovered for the next session.
    Fix
    Limit conditioning to 1-2 sessions per week, placed on upper body days. Keep it low impact if possible, and monitor how your legs feel on lower power day.
  • Mistake
    Following a generic PHUL template without adjusting volume or frequency to your own recovery.
    Why
    The cookie-cutter version works for many intermediates, but some people need fewer sets on hypertrophy days or an extra rest day between lower power and upper hypertrophy. Ignoring this leads to plateau or injury.
    Fix
    After 4 weeks, check your progress on power lifts. If bench or squat haven't increased, reduce total hypertrophy sets by 1-2 per muscle group. You can also shift the split to a 4-day rotation with a rest day after the second lower day.
