The Nexus Labs Classic Physique Split
A 6-Day Muscle-Building Program for a Bigger Chest, Wider Back, Capped Shoulders, Thick Arms & Powerful Legs
Build first. Cut later.
If your goal is to build an impressive, aesthetic physique, simply getting stronger or gaining bodyweight isn't enough.
You need proportion.
A great physique is built around visual balance: a full upper chest, wide lats, round shoulders, thick arms, developed legs, and a tight-looking waist. That's the philosophy behind the NeXus Labs Classic Physique Split.
This six-day program takes inspiration from the training principles associated with modern classic-physique bodybuilding—including the style popularized by athletes such as Chris Bumstead—while creating a NeXus Labs approach of our own.
The goal is straightforward:
Build quality muscle now. Keep fat gain controlled. Then enter your February cut with more muscle to reveal.
Why This Split?
A lot of workout programs treat every muscle group equally.
That's not necessarily the best approach when you're trying to build an aesthetic physique.
The NeXus Labs split gives additional attention to the muscles that create the classic V-taper and muscular silhouette:
- Upper chest for thickness and fullness
- Lats for back width
- Side and rear delts for shoulder width
- Biceps and triceps for arm thickness
- Quads and hamstrings for complete lower-body development
- Core and waist control to maintain the visual taper
We're not chasing random exercises.
We're building a physique.
The Nexus Labs Weekly Split
| Day | Training |
|---|---|
| Day 1 | Chest + Triceps |
| Day 2 | Back + Biceps |
| Day 3 | Recovery |
| Day 4 | Shoulders + Arms |
| Day 5 | Legs |
| Day 6 | Upper Physique |
| Day 7 | Rest |
The sixth training day is intentional.
Instead of simply adding more volume everywhere, we use Day 6 to reinforce the areas that contribute most to the physique we're trying to build.
DAY 1 — CHEST + TRICEPS
The Goal: Build a Thick, Full Upper Chest
The chest workout begins with a pre-exhaust/activation movement before moving into heavier pressing.
1. Pec Deck Fly
3 × 15–20
Focus on getting a deep stretch and squeezing the pecs rather than simply moving the stack.
2. Incline Dumbbell Press
4 × 6–10
This is the primary mass-building movement of the session.
Control the negative, keep your chest engaged, and don't turn the exercise into a shoulder press.
3. Incline Machine Press
3 × 8–12
Machines allow you to push the chest hard while maintaining stability.
4. Cable Fly
3 × 12–15
Focus on constant tension and a controlled stretch.
5. Push-Ups
2 × near failure
Finish the chest with controlled reps rather than racing through them.
Triceps
Rope Pushdown — 3 × 10–15
Overhead Cable Extension — 3 × 10–15
Machine Dips — 2 × 8–12
Day 1 Focus
Upper chest first. Triceps second. Quality reps over ego weight.
DAY 2 — BACK + BICEPS
The Goal: Build the V-Taper
A wide back changes the entire appearance of your physique.
The objective isn't simply to make your back thicker. We want to develop both lat width and upper-back thickness.
1. Neutral-Grip Lat Pulldown
4 × 8–12
Think about driving your elbows toward your hips.
2. Chest-Supported Row
3 × 8–12
Use controlled reps and avoid using momentum to move the weight.
3. Single-Arm Cable Lat Pulldown
3 × 10–15 per side
Excellent for establishing a strong mind-muscle connection with the lats.
4. Machine High Row
3 × 8–12
Focus on upper-back thickness while keeping the movement controlled.
5. Straight-Arm Pulldown
3 × 12–15
Keep tension on the lats throughout the movement.
6. Rear-Delt Cable Fly
3 × 15–20
Rear delts help create that complete three-dimensional shoulder appearance.
Biceps
Incline Dumbbell Curl — 3 × 8–12
Preacher Curl — 3 × 10–12
Hammer Curl — 2 × 10–15
Day 2 Focus
Think about training your back—not simply moving weight from point A to point B.
DAY 3 — RECOVERY
Recovery Is Part of the Program
One of the biggest mistakes people make during a muscle-building phase is believing that more training automatically means more growth.
It doesn't.
Training provides the stimulus.
Recovery allows you to adapt.
Use Day 3 for:
- 20–30 minutes of easy cardio or walking
- Mobility work
- Light stretching
- Hydration
- Quality nutrition
- Sleep
You should finish the day feeling better, not exhausted.
DAY 4 — SHOULDERS + ARMS
The Goal: Build 3D Shoulders and Thick Arms
If you're trying to create a classic physique, shoulder development is critical.
The side delts create width.
The rear delts add depth.
The front delts contribute to overall shoulder mass.
And bigger arms complete the look.
Shoulders
Machine Shoulder Press — 3 × 6–10
Dumbbell Lateral Raise — 4 × 10–15
Cable Lateral Raise — 3 × 12–20
Reverse Pec Deck — 3 × 15–20
Don't turn lateral raises into momentum exercises.
Controlled reps win here.
Arms
EZ-Bar Curl — 3 × 8–12
Overhead Cable Triceps Extension — 3 × 8–12
Preacher Curl — 3 × 10–15
Rope Pushdown — 3 × 10–15
Hammer Curl — 2 × 12–15
Single-Arm Pushdown — 2 × 12–15
Day 4 Focus
Make the delts work. Make the arms work. Leave the ego at the door.
DAY 5 — LEGS
The Goal: Build Legs That Match the Upper Body
A classic physique isn't complete with a great upper body and underdeveloped legs.
This session attacks both the quads and hamstrings while giving the calves dedicated work.
1. Hack Squat
4 × 6–10
Your primary heavy quad movement.
2. Leg Press
3 × 10–15
Controlled reps and a full range of motion that you can perform safely.
3. Bulgarian Split Squat
3 × 8–12 per leg
Uncomfortable?
Good.
Stay controlled.
4. Leg Extension
3 × 12–15
Use a deliberate contraction rather than bouncing the weight.
5. Romanian Deadlift
3 × 8–12
Focus on hamstring tension and controlled movement.
6. Seated Leg Curl
3 × 10–15
7. Lying Leg Curl
2 × 12–15
Calves
Standing Calf Raise — 4 × 8–12
Seated Calf Raise — 3 × 12–20
Day 5 Focus
Don't skip the movements that are difficult. They're usually the ones you need most.
DAY 6 — UPPER PHYSIQUE
The Goal: Put the Finishing Touches on the Physique
This isn't another random upper-body workout.
It's a strategic session designed to reinforce the muscles that create the classic physique look.
1. Incline Smith Press
3 × 8–10
2. Wide-Grip Lat Pulldown
3 × 8–12
3. Machine Chest Press
2 × 10–12
4. Chest-Supported Row
3 × 8–12
5. Cable Lateral Raise
4 × 12–20
6. Pec Deck
2 × 12–15
7. EZ-Bar Curl
3 × 10–12
8. Rope Pushdown
3 × 10–15
This workout gives additional attention to the upper chest, lats, shoulders and arms—the areas that help create the visual proportions we're after.
HOW TO TRAIN
The exercise list is only half of the program.
How you perform those exercises matters.
Train Close to Failure
You don't need to take every set to absolute failure.
For most working sets, aim to finish with approximately:
1–2 reps in reserve (RIR).
In other words, you should feel like you could have completed another one or two good reps.
For selected isolation exercises, particularly on the final set, you can occasionally push closer to failure.
CONTROL THE NEGATIVE
Don't throw the weight around.
A good general guideline is approximately:
2–3 seconds on the eccentric portion.
That doesn't mean every repetition needs to be painfully slow.
It means you should remain in control.
The goal is to make the target muscle work—not to impress the person three machines away.
REST BETWEEN SETS
Heavy compound movements
2–3 minutes
Machine movements
90–120 seconds
Isolation movements
60–90 seconds
Don't artificially shorten your rest just to make the workout harder.
If you need another minute to produce a strong set, take it.
THE NEXUS LABS PROGRESSION SYSTEM
Don't Just Work Out. Track Your Workouts.
One of the simplest ways to make your training more effective is to keep a logbook.
Here's the system:
Example
Incline Dumbbell Press:
Week 1:
70 lb × 8
70 lb × 8
70 lb × 7
70 lb × 7
Week 2:
70 lb × 9
70 lb × 9
70 lb × 8
70 lb × 8
Week 3:
70 lb × 10
70 lb × 10
70 lb × 10
70 lb × 10
You've now reached the top of the prescribed range.
Next time, increase the weight.
That's progressive overload.
Small improvements repeated over months can produce dramatic changes.
DON'T CHASE WEIGHT AT THE EXPENSE OF FORM
There's a difference between progressive overload and ego lifting.
If increasing the weight causes:
- Shortened range of motion
- Excessive momentum
- Loss of control
- Poor positioning
- The wrong muscle taking over
then you may have increased the weight without actually improving the stimulus.
Earn the heavier weight.
NUTRITION: BUILD MUSCLE WITHOUT GETTING SLOPPY
The goal of this phase isn't to gain as much bodyweight as possible.
It's to build muscle while keeping unnecessary fat gain under control.
That means avoiding the traditional:
"I'm bulking, so I can eat whatever I want."
approach.
Instead, think controlled muscle gain.
Prioritize Protein
Protein provides the amino acids your body needs to support muscle repair and growth.
A practical target for many lifters is approximately:
0.7–1.0 grams of protein per pound of bodyweight per day.
Individual needs vary, but consistency matters more than chasing a perfect number.
Don't Fear Carbohydrates
Carbohydrates are useful fuel for hard training.
Place a significant portion of your daily carbohydrate intake around your training window if that helps you perform and recover better.
Keep Your Surplus Controlled
You don't need a massive calorie surplus.
A modest surplus allows you to pursue muscle growth while limiting unnecessary fat accumulation.
Track:
- Bodyweight
- Waist measurement
- Gym performance
- Progress photos
- Recovery
- Energy
If weight is climbing rapidly and your waist is increasing significantly, your surplus may be too aggressive.
THE FEBRUARY CUT
The muscle-building phase has a purpose.
Build the physique first. Then reveal it.
When February arrives, the objective changes.
You're no longer trying to maximize weight gain.
You're trying to retain as much muscle as possible while reducing body fat.
That means you don't need to completely reinvent your training.
Keep your resistance training challenging.
Keep your compound movements.
Keep your protein high.
Then create a controlled calorie deficit.
Your cardio can gradually increase as needed, but resistance training remains a priority.
WHY WE DON'T CHANGE THE PROGRAM EVERY TWO WEEKS
Social media makes it easy to fall into the trap of constantly searching for the next workout.
One week it's a new chest routine.
The next week it's a new "secret" shoulder exercise.
Then someone tells you that your entire split is wrong.
Don't fall for it.
Muscle building requires enough consistency to determine whether a program is actually working.
Give the program time.
Track your performance.
Track your physique.
Make adjustments based on data—not boredom.
COMMON MISTAKES
1. Training for the Pump Instead of Progress
A great pump feels good.
But your long-term goal is to progressively stimulate the muscle.
2. Taking Every Set to Failure
Failure has a place.
It doesn't need to be the destination of every set.
3. Ignoring Recovery
Six training days doesn't mean six days of destroying yourself.
Recovery is part of the plan.
4. Eating Too Much
A dirty bulk can add bodyweight quickly without producing the physique you're actually after.
5. Neglecting Legs
Your physique is only as complete as its weakest major muscle group.
6. Not Tracking
If you don't know what you lifted last week, it's difficult to systematically improve.
THE NEXUS LABS PHYSIQUE CHECKLIST
Before you start the program, take baseline measurements.
Record:
Bodyweight: __________
Waist: __________
Chest: __________
Arms: __________
Thighs: __________
Then take progress photos:
- Front
- Side
- Back
Take them under similar lighting and conditions each time.
Don't judge your progress based on a single day.
Look at the trend.
THE REAL GOAL
The goal of the Nexus Labs Classic Physique Split isn't to become a copy of another athlete.
It's to use proven bodybuilding principles to build your best physique.
We took inspiration from the classic-physique approach—proportion, symmetry, muscularity and aesthetics—and built a program around those priorities.
Big upper chest.
Wide back.
Capped shoulders.
Thick arms.
Developed legs.
Controlled waist.
And most importantly:
Progressive, consistent training.
READY TO BUILD?
Don't just read the program.
Run it.
Track every workout.
Write down every weight.
Earn every increase.
Take your progress photos.
Fuel your body.
Recover.
And when February comes, you'll have something worth revealing.
Build first. Cut later.
This is the Nexus Labs Classic Physique Split.
Train with purpose. Build with discipline. Reveal what you built.
