Upper/Lower Split: The Complete Setup and Execution Guide

The upper/lower split is one of the most versatile and effective training structures for intermediate lifters. It hits each muscle group twice per week, balances pushing and pulling, and offers enough flexibility to fit most schedules.

Here's everything you need to set up an upper/lower split that actually works.

Why Upper/Lower Works

The research is clear: training each muscle group twice per week produces better results than once weekly training for most lifters. A meta-analysis by Schoenfeld et al., 2016 found that training a muscle 2+ times per week was superior for hypertrophy compared to once-weekly training.

Upper/lower delivers this naturally. You train upper body twice and lower body twice, hitting each muscle group with adequate frequency while allowing sufficient recovery between sessions.

Iridium can program an upper/lower split for you automatically — just tell the app you have 4 days per week to train and it builds complete A/B sessions with appropriate volume, exercise selection, and progression already built in. No manual programming required.

Key Benefits

• Optimal frequency: Each muscle trained 2x per week
• Balanced development: Upper and lower get equal attention
• Flexible scheduling: Works as 3, 4, or 5-day programs
• Manageable sessions: 60-75 minutes per workout
• Recovery-friendly: 2-3 days between same muscle groups

The Basic Structure

A standard 4-day upper/lower looks like this:

You can also run it 3 days per week on a rotating schedule:

• Week 1: Upper A, Lower A, Upper B
• Week 2: Lower B, Upper A, Lower A
• Week 3: Upper B, Lower B, Upper A

This rotation ensures each muscle gets trained every 4-5 days, which still falls within the optimal frequency range.

Upper Day Exercise Selection

Each upper day should include:

1. Horizontal push (bench press, dumbbell press)
2. Horizontal pull (rows)
3. Vertical push (overhead press)
4. Vertical pull (pulldowns, pull-ups)
5. Arm work (optional, 2-4 sets total)

Sample Upper A (Strength Focus)

Sample Upper B (Hypertrophy Focus)

Notice how Upper A emphasizes lower reps and compound movements, while Upper B uses more moderate rep ranges and includes isolation work. This variation provides different stimuli while hitting the same muscle groups.

Lower Day Exercise Selection

Each lower day should include:

1. Quad-dominant compound (squat variation)
2. Hip-hinge (deadlift variation, RDL)
3. Unilateral work (lunges, split squats)
4. Hamstring isolation (leg curls)
5. Calf work (2-3 sets)

Sample Lower A (Strength Focus)

Sample Lower B (Hypertrophy Focus)

Volume Distribution

For upper/lower, distribute your weekly volume across both sessions. A reasonable starting point based on Schoenfeld et al., 2017:

Start at the lower end and increase volume only when progress stalls and recovery remains good.

Progression Strategy

Progressive overload is still the primary driver of gains. Use these methods:

Weight increases: When you hit the top of your rep range for all sets, add weight next session.

Rep progression: If you can't add weight, add reps until you reach the top of your range.

Set progression: Periodically add a set to lagging muscle groups, then reduce and increase intensity.

Double progression works well here: work within a rep range (e.g., 8-12), and only add weight when you can complete all sets at the top of the range.

Common Mistakes

1. Too Much Arm Work

Your arms get significant work from compounds. Many lifters add 6-8 sets of direct arm work per session when 2-4 is plenty. Start conservatively.

2. Neglecting Leg Volume

Upper days tend to get more attention. Make sure lower body volume matches or exceeds upper body — lower body muscles are larger and can typically handle more work.

3. No Exercise Variation

Using the exact same exercises on A and B days misses the point. Vary your exercise selection to target muscles from different angles and loading patterns.

4. Skipping Vertical Pulls

Many lifters prioritize pressing over pulling, and horizontal over vertical. Make sure vertical pulls (pull-ups, pulldowns) get adequate attention for complete back development.

Who Should Use Upper/Lower?

Upper/lower works best for:

• Intermediate lifters with 1-2 years of training experience
• Anyone who can train 3-5 days per week consistently
• Lifters wanting balanced development rather than specialization
• Those who find full body too fatiguing but bro splits too infrequent

It's less ideal for:

• Complete beginners (full body 3x/week is usually better)
• Advanced lifters who may need more volume per muscle group
• Those who can only train 2 days per week

Transitioning to Upper/Lower

If you're coming from a bro split, expect an adjustment period. Your muscles aren't used to being trained twice weekly with less volume per session. Start with moderate volume and increase over 4-6 weeks.

If you're coming from full body, the transition is smoother. You're already used to frequency — now you're just distributing it differently.

Tracking Your Progress

An upper/lower split involves managing multiple muscle groups across multiple sessions. Effective tracking helps you:

• See weekly volume per muscle group at a glance
• Track progression on key lifts
• Identify when you need more recovery or a deload
• Notice patterns in performance (better on Upper A vs B?)

Iridium automatically calculates your weekly volume per muscle group based on your logged sets. You can see exactly how much work each muscle is getting and tell when you're pushing too hard or easing up too much. The app also tracks progression on key lifts, showing when you've hit plateaus or when it's time to increase weight.

Sample 4-Week Block

Here's a progression scheme for a 4-week training block:

Week 1: Baseline — establish weights for all rep ranges Week 2: Add 1 rep per set where possible Week 3: Hit top of rep ranges, increase weight on exercises where you succeed Week 4: Deload — reduce volume by 40-50%, maintain intensity

Repeat with new baseline weights.

Final Thoughts

The upper/lower split is a proven, research-supported approach to training that works for the majority of intermediate lifters. It delivers optimal frequency, manageable session lengths, and enough flexibility to fit real-world schedules.

Start with the templates above, adjust volume based on your recovery, and focus on progressive overload. The structure works — now execute consistently.
