Upper-Lower Split for Strength and Size: Balance Maximum Gains with Sustainable Training
Published: Training Program Design Guide
You want to build serious strength and muscle, but you can't commit to 6-day training weeks—so what's the most effective 4-day program? If you're choosing between different training splits and wondering whether Upper-Lower is right for your goals, here's the science: Upper-Lower splits deliver optimal training frequency (2x per week per muscle) with manageable session lengths, making them ideal for intermediate lifters focused on both strength and hypertrophy. Here's how to design an Upper-Lower program that maximizes your progress.
What is an Upper-Lower Split?
An Upper-Lower split divides your training into upper body workouts (chest, back, shoulders, arms) and lower body workouts (quads, hamstrings, glutes, calves). This simple yet highly effective division allows you to train each muscle group 2-3 times per week with adequate recovery, making it one of the most scientifically-supported training splits for both strength and hypertrophy.
The Upper-Lower split is typically run 4 days per week (Upper-Lower-Upper-Lower), though variations with 5 or 6 days exist. This structure balances training frequency, volume, and recovery more effectively than once-per-week body part splits while being more manageable than 6-day Push-Pull-Legs programs.
Why This Matters for Strength Athletes and Lifters
The Upper-Lower split isn't just convenient—it's strategically designed to maximize strength development and muscle growth simultaneously. For serious lifters, this training structure offers unique advantages:
🏋️ Training Benefits
- ✓ Optimal Strength Frequency: Train major lifts (bench, squat, deadlift) twice weekly for faster strength gains without excessive CNS fatigue
- ✓ Hypertrophy Frequency: 2x weekly muscle stimulation maximizes protein synthesis throughout the week while allowing 48-72 hours recovery
- ✓ Sustainable Volume: 60-75 minute sessions prevent the mental burnout common with 90+ minute full-body or PPL workouts
- ✓ Strength-Hypertrophy Balance: Perfect for lifters who want to get stronger AND bigger—you can program both strength work (3-5 reps) and hypertrophy work (8-12 reps) in the same week
- ✓ Sport Compatibility: 4-day structure leaves room for sport-specific training, unlike 6-day programs that monopolize your schedule
- ✓ Balanced Development: Training all upper body muscles together prevents the imbalances common in push/pull splits where chest and back are separated by multiple days
Why Upper-Lower Splits Work: The Research
The effectiveness of Upper-Lower programming is backed by multiple evidence-based principles. Research teams at McMaster University and the Norwegian School of Sport Sciences have extensively studied training frequency and its impact on strength and hypertrophy adaptations.
Optimal Training Frequency: 2x per week frequency maximizes protein synthesis without excessive fatigue
Volume Distribution: 48 hours between training the same muscles allows full recovery
Strength and Hypertrophy Balance: Supports both compound strength work and accessory volume
Practical Adherence: 4-day commitment is sustainable for most people long-term
📊 What Research Shows
A 2016 meta-analysis by Brad Schoenfeld and colleagues at Lehman College analyzed 25 studies on training frequency and muscle hypertrophy. The research demonstrated that training each muscle group 2x per week produced significantly greater muscle growth compared to 1x per week when total volume was equated. The study found approximately 6.8% greater hypertrophy with twice-weekly training.
Practical takeaway: This is exactly what 4-day Upper-Lower delivers—each muscle trained twice weekly with optimal recovery between sessions. The National Strength and Conditioning Association recommends this frequency for intermediate to advanced lifters seeking balanced strength and size gains.
Additional research from the University of Tampa showed that Upper-Lower splits allow athletes to train compound movements (squat, bench, deadlift) with higher quality compared to full-body routines, because fatigue doesn't accumulate across all movement patterns in one session.
Training Split Comparison
How Upper-Lower Compares
| Split Type | Days/Week | Frequency | Best For |
|---|---|---|---|
| Full Body | 3 | 3x per muscle | Beginners, fat loss |
| Upper-Lower | 4 | 2x per muscle | Strength + hypertrophy |
| Push-Pull-Legs | 6 | 2x per muscle | Pure hypertrophy |
| Bro Split | 5 | 1x per muscle | Advanced bodybuilders |
Upper-Lower Frequency Options
4-Day Upper-Lower (Most Common)
Schedule: Upper - Lower - Rest - Upper - Lower - Rest - Rest
Best for:
- Intermediate to advanced lifters
- Balanced strength and hypertrophy goals
- Those who can commit to 4 training days weekly
- Powerlifters and strength athletes
Frequency: Each muscle trained 2x per week with 2-3 days recovery between same-muscle sessions.
5-Day Upper-Lower
Schedule: Week 1: U-L-U-L-U | Week 2: L-U-L-U-L (alternating pattern)
This creates a 2.5x weekly frequency for each muscle group—excellent for advanced lifters who can handle higher volumes and recover well.
3-Day Upper-Lower
Schedule: Week 1: Upper - Lower - Upper | Week 2: Lower - Upper - Lower
This creates 1.5x weekly frequency. Good option for beginners or those with limited training availability, though less optimal than 4-day versions.
Designing Your Upper Body Days
Upper days should target all major upper body muscle groups: chest, back, shoulders, and arms.
Upper Body Exercise Structure
Exercise Order:
- Horizontal Press (Chest): Bench press variations - 3-4 sets
- Vertical Pull (Back Width): Pull-ups, lat pulldowns - 3-4 sets
- Overhead Press (Shoulders): Barbell or dumbbell OHP - 3 sets
- Horizontal Pull (Back Thickness): Rows (barbell, cable, DB) - 3-4 sets
- Accessory Press: Incline press, dips - 2-3 sets
- Biceps Work: Curls variations - 2-3 sets
- Triceps Work: Extensions, pushdowns - 2-3 sets
Sample Upper Day 1 (Strength Focus):
- Barbell Bench Press: 4 sets of 5 reps
- Pull-Ups (Weighted): 4 sets of 6-8 reps
- Overhead Press: 3 sets of 6-8 reps
- Barbell Rows: 4 sets of 8 reps
- Incline Dumbbell Press: 3 sets of 10 reps
- Barbell Curls: 3 sets of 8-10 reps
- Skull Crushers: 3 sets of 10 reps
Total: ~24 sets, 60-75 minutes
Sample Upper Day 2 (Hypertrophy Focus):
- Dumbbell Bench Press: 4 sets of 10 reps
- Lat Pulldowns: 4 sets of 12 reps
- Dumbbell Overhead Press: 3 sets of 10-12 reps
- Cable Rows: 3 sets of 12 reps

- Face Pulls: 3 sets of 15 reps
- Hammer Curls: 3 sets of 12 reps
- Tricep Rope Pushdowns: 3 sets of 12 reps
Total: ~26 sets, 60-75 minutes
Balancing Push and Pull Volume
A common mistake is programming excessive pushing volume relative to pulling, leading to shoulder issues and postural imbalances.
Critical: Pull Volume Should Equal or Exceed Push Volume
For every set of horizontal pressing (bench press), you should perform at least one set of horizontal pulling (rows). For every set of overhead pressing, perform rear delt work (face pulls). This 1:1 or 1:1.5 push-to-pull ratio prevents shoulder impingement, maintains scapular health, and promotes balanced development.
Designing Your Lower Body Days
Lower days should target quads, hamstrings, glutes, and calves with a balance of compound and isolation movements.
Lower Body Exercise Structure
Exercise Order:
- Primary Squat Pattern: Back squat, front squat, safety bar squat - 3-5 sets
- Hip Hinge Pattern: Deadlifts, Romanian deadlifts - 3-4 sets
- Unilateral/Quad Focus: Bulgarian split squats, lunges, leg press - 3 sets
- Hamstring Isolation: Leg curls, Nordic curls - 3 sets
- Glute Isolation: Hip thrusts, glute bridges - 3 sets
- Calf Work: Standing or seated calf raises - 3-4 sets
Sample Lower Day 1 (Squat Focus):
- Barbell Back Squat: 4 sets of 5 reps
- Romanian Deadlifts: 4 sets of 8 reps
- Bulgarian Split Squats: 3 sets of 10 reps per leg
- Leg Curls: 3 sets of 12 reps
- Standing Calf Raises: 4 sets of 12 reps
Total: ~18 sets, 60-70 minutes
Sample Lower Day 2 (Deadlift Focus):
- Conventional Deadlifts: 4 sets of 5 reps
- Front Squats: 3 sets of 8 reps
- Walking Lunges: 3 sets of 12 reps per leg
- Leg Press: 3 sets of 15 reps
- Nordic Curls: 3 sets of 6-8 reps
- Seated Calf Raises: 4 sets of 15 reps
Total: ~20 sets, 60-70 minutes
Squat vs. Deadlift Emphasis
For 4-day Upper-Lower, you can structure lower days with different emphases:
- Lower 1: Heavy squats (5 reps), moderate deadlifts (8 reps)
- Lower 2: Heavy deadlifts (5 reps), moderate squats (8 reps)
This allows you to prioritize both movements without excessive CNS fatigue from heavy squats and deadlifts in the same session.
Volume Guidelines for Upper-Lower
Weekly volume should align with research-backed hypertrophy ranges. According to studies from the University of Jyväskylä and position stands from the American College of Sports Medicine, optimal weekly training volume varies by muscle group size and training status:
Weekly Set Targets (4-Day Upper-Lower):
- Chest: 12-18 sets (6-9 sets per upper day)
- Back: 15-22 sets (8-11 sets per upper day)
- Shoulders: 12-18 sets (6-9 sets per upper day)
- Arms (Biceps/Triceps): 12-16 sets each (6-8 sets per upper day)
- Quads: 12-20 sets (6-10 sets per lower day)
- Hamstrings: 10-16 sets (5-8 sets per lower day)
- Glutes: 8-14 sets (4-7 sets per lower day)
- Calves: 12-16 sets (6-8 sets per lower day)
Progressive Overload Strategies
Upper-Lower splits excel at progressive overload because you train movements twice per week:
Double Progression Method
Use different rep ranges between sessions:
- Upper 1: Bench press 4×5 at 185 lbs (strength)
- Upper 2: Dumbbell press 4×10 at 60 lbs (hypertrophy)
Progress weight on the strength day, progress reps on the hypertrophy day.
Wave Loading
Vary intensity across weeks:
- Week 1: Squat 3×5 at 80% 1RM
- Week 2: Squat 4×5 at 82.5% 1RM
- Week 3: Squat 5×5 at 85% 1RM
- Week 4: Deload - Squat 3×5 at 70% 1RM
Upper-Lower for Different Goals
Powerlifting Upper-Lower
Emphasize competition lifts with higher frequency and lower reps:
- Upper 1: Competition bench (heavy), close-grip bench (volume)
- Upper 2: Competition bench (volume), overhead press (strength)
- Lower 1: Competition squat (heavy), deficit deadlift
- Lower 2: Competition deadlift (heavy), pause squats
Bodybuilding Upper-Lower
Higher rep ranges, more isolation work, shorter rest periods:
- More exercises per session (7-9 vs 5-7)
- Higher rep ranges (8-15 vs 5-10)
- Additional isolation exercises for lagging muscle groups
- Techniques like drop sets, supersets, rest-pause sets

Weekend: Rest / Active Recovery
Common Questions About Upper-Lower Splits
Should I do upper-lower or push-pull-legs?
Choose based on your schedule and goals. If you can train 6 days per week and prioritize pure hypertrophy, choose Push-Pull-Legs. If you train 4 days per week and want balanced strength and muscle development, Upper-Lower is superior. Upper-Lower also works better for powerlifters because you can hit main lifts (bench, squat, deadlift) twice weekly with appropriate volume.
Can beginners use upper-lower splits?
Beginners with 3-6 months of training experience can transition to Upper-Lower, but true beginners (0-3 months) should start with full-body routines 3x per week. Once you've built base strength and work capacity, Upper-Lower becomes highly effective. The 3-day rotating Upper-Lower is a good bridge between full-body and 4-day programs.
How do I prevent muscle imbalances on upper-lower?
The key is maintaining a 1:1 or higher pull-to-push ratio. For every set of bench press, do a set of rows. For every set of overhead press, do rear delt work. Track your weekly volume per muscle group to ensure balanced development. Read our guide on fixing muscle imbalances for detailed strategies.
Should upper days be identical or different?
They should be different. Use Upper 1 for strength work (3-6 reps with barbells) and Upper 2 for hypertrophy work (8-12 reps with dumbbells and cables). This provides varied stimulus, prevents boredom, and allows you to progress both strength and size simultaneously. Alternating heavy and moderate days also manages fatigue better than two identical heavy sessions.
How do I track upper-lower workouts in FitnessRec?
In FitnessRec, create a 4-day program with four distinct workouts: Upper 1, Lower 1, Upper 2, and Lower 2. Set different exercises and rep ranges for each session. When logging workouts, FitnessRec shows session-specific history—"Last Upper 1" displays your previous Upper 1 performance, not Upper 2. The Volume Analytics dashboard tracks weekly sets per muscle group, helping you maintain optimal ranges (12-18 sets for chest, 15-22 for back, etc.). Learn more in our comprehensive tracking guide.

Pro Tip: AMRAP Top Sets
On your final working set of major compounds (bench, squat, deadlift), perform an AMRAP (as many reps as possible) set. This auto-regulation technique ensures you're pushing progression when strong and backing off when fatigued. Use FitnessRec to track these AMRAP sets and calculate estimated 1RMs—you'll see strength gains week-to-week even when working weights stay constant.
The Upper-Lower split represents the optimal balance between training frequency, session length, and recovery for most intermediate lifters. By training each muscle group twice per week across four focused sessions, you maximize hypertrophy and strength gains while maintaining a sustainable schedule. With proper programming and tracking through FitnessRec, Upper-Lower splits can produce exceptional results for years of consistent progress.
