The Best 5 Day Workout Split for Muscle Growth (Full Programme)

Five days a week is where training stops being purely about hitting minimums and starts being about allocation. You have every muscle group covered twice with a day left over, and what you do with that fifth day is the interesting decision.

Option 1: Upper / Lower / Push / Pull / Legs (recommended)

The hybrid. Two upper/lower days, then a PPL rotation for the back half of the week.

Why it’s the best five-day structure: chest, shoulders, triceps, back, biceps and legs all get trained twice a week. The heavy upper/lower days at the front cover strength while you’re fresh; the PPL days at the back add volume with more isolation work.

Session shape:

• Upper (heavy): Bench Press 4×5, Barbell Row 4×6, Overhead Press 3×6–8, Pull Up 3×AMRAP, Lateral Raise 3×15
• Lower (heavy): Back Squat 4×5, Romanian Deadlift 3×8, Leg Press 3×10, Leg Curl 3×12, Calf Raise 4×15
• Push (volume): Incline Dumbbell Press 4×8–10, Dumbbell Shoulder Press 3×10–12, Chest Dip 3×12, Cable Flye 3×15, Lateral Raise 4×15–20, Triceps Pushdown 3×12
• Pull (volume): Lat Pulldown 4×10–12, Seated Cable Row 4×12, Dumbbell Row 3×12, Face Pull 3×20, Incline Dumbbell Curl 3×12, Hammer Curl 3×12
• Legs (volume): Front Squat 3×8–10, Bulgarian Split Squat 3×10, Hip Thrust 3×12, Leg Extension 3×15, Leg Curl 3×15, Calf Raise 4×20

Option 2, Four days + a specialisation day

Run the four-day upper/lower split exactly as written, then add a fifth day dedicated entirely to whatever’s lagging.

The specialisation day should be low fatigue and high focus: 8–12 sets of mostly isolation work for one or two muscle groups, trained first while you’re fresh.

If your arms lag: Barbell Curl, Incline Dumbbell Curl, Hammer Curl, Overhead Triceps Extension, Triceps Pushdown; 3 sets each, 10–15 reps.

If your shoulders lag: Dumbbell Shoulder Press, Lateral Raise ×2 variations, Rear Delt Flye, Face Pull.

This is the cleanest way to bring up a body part without disturbing a programme that’s already working.

Option 3: The classic 5-day body-part split

Chest, back, shoulders, legs, arms, one day each.

The honest assessment: this is the most popular five-day split and the least effective of the three. Every muscle group is trained once a week. At matched weekly volume, twice-weekly frequency produces more growth.

It isn’t useless: high per-session volume, and the structure is motivating for people who like a “chest day”. But if your goal is maximum muscle per unit of effort, options 1 and 2 beat it.

Volume: the five-day trap

The failure mode of five-day training is treating each session like it’s your only one.

Twenty sets of chest on Monday because it’s “chest day” doesn’t build twice as much as ten. Past roughly ten hard sets in one session for one muscle group, the extra work adds fatigue faster than stimulus.

Weekly targets don’t change because you added a day:

• 12–20 hard sets per muscle group per week
• Spread across two sessions rather than crammed into one
• 1–3 reps in reserve on compounds

The fifth day is for redistributing volume, not for adding a fifth session’s worth on top of a four-day programme.

Five days a week means five opportunities for fatigue to accumulate and only two days for it to clear. Most people who burn out on a five-day split didn’t train too often: they trained too hard, too often, without ever deloading.

Recovery on five days

Sleep is the limiter. Seven hours won’t sustain five hard sessions. Eight is the working minimum, and if you can’t get it, run four days instead.

Deload every 6 weeks, not eight. The higher the frequency, the sooner fatigue outruns adaptation.

Watch the lifts, not the soreness. Soreness is a poor recovery signal. Stalled or regressing numbers across two consecutive weeks is the real one.

Put conditioning on the two rest days, and keep it easy. Zone 2 work aids recovery; interval work competes with it.

Progression

Double progression on everything:

1. Rep range per exercise (5–8 compounds, 8–12 or 12–20 isolation).
2. Add reps until you top the range on all sets.
3. Add weight, reset to the bottom.

On five days, you get two attempts a week at most lifts. That’s fast feedback: a lift that hasn’t moved in three weeks is genuinely stalled, not just unlucky. Change the rep range first, the exercise second, and take a deload if two or more lifts stall at once.

Common mistakes

Five days because more must be better. If four days is producing progress, five adds fatigue for marginal return. Add the day when you have a specific reason: a weak point, or volume you genuinely can’t fit.

Arms day as the fifth day by default. Arms get substantial indirect work from every press and pull. Specialise on what’s actually lagging, which for most people is the upper back or hamstrings.

No rest day until the weekend. Five consecutive sessions means the last two run on empty. Break the week up.

Skipping deloads. The most common way a good five-day programme ends.

ForgeFit counts your weekly hard sets per muscle group as you log, so “12–20 sets” is something you check rather than estimate, and when a lift stalls, the history is right there to show you whether it’s three weeks flat or one bad session.
