Body Recomp Training Split: 4-Day Upper/Lower Done Right (2026)

Body recomposition asks your body to do two contradictory things at once: lose fat and build muscle. Most of the protein and calorie math gets the attention, but the training split is the structural decision that determines whether your recomp actually works or just becomes a slow cut. Pick the wrong split and you burn through recovery capacity, lose lean mass, and stall by week 8. Pick the right split and the calorie deficit becomes survivable while the hypertrophy stimulus stays intact.

This article gives you the evidence-based split for recomp — a 4-day upper/lower — with weekly set targets, exercise selection, session structure, and deload cadence. Plug your stats into the body recomposition calculator for personalized macros that match this training load.

Why 4-Day Upper/Lower Wins for Recomp

Two findings drive split selection during recomposition:

1. Frequency matters more than total volume per session. Schoenfeld, Ogborn & Krieger 2016 (PMID 26605807) meta-analyzed 10 studies and found that training each muscle group twice per week produced 48% more hypertrophy than once-per-week training when total weekly volume was matched. The 2x-frequency effect is the single largest training variable in the literature.
2. Recovery cost scales nonlinearly under a deficit. Helms et al. 2014 (PMID 24092765) documented that natural lifters in a calorie deficit need 20-30% more rest between hard sessions than the same lifters during a surplus. The deficit raises perceived exertion, slows protein synthesis recovery, and shortens the productive workout window.

A 4-day upper/lower hits both constraints. Each muscle group trains 2x per week (frequency met). Sessions are 50-65 minutes, not 90-plus (recovery cost contained). Three rest days per week is enough buffer for sleep and active recovery to do their work. Hard volume sits at 12-18 sets per muscle group per week, which is the productive band per Schoenfeld 2017 without crossing into the over-reaching zone that compounds under a deficit.

The Weekly Template

The standard 4-day upper/lower schedules workouts on Monday, Tuesday, Thursday, Friday — with Wednesday, Saturday, and Sunday as rest. The pairing avoids back-to-back upper or lower days, which lets glycogen and central nervous system fatigue clear between sessions.

The A/B differentiation matters. Upper A leads with horizontal press (bench), Upper B leads with horizontal pull (row). Lower A leads with squat, Lower B leads with hinge (Romanian deadlift). This rotation gives each major movement pattern fresh-CNS priority once per week and lets the other pattern serve as supplementary work. Lifters who run identical Upper A and Upper B sessions consistently report shoulder/elbow grinding by week 6.

Exercise Selection

Upper A (Push-Emphasis)

• Barbell or dumbbell bench press — 4 sets x 5-8 reps (heavy compound)
• Standing or seated overhead press — 3 sets x 6-10 reps
• Incline dumbbell press — 3 sets x 8-12 reps
• Chest-supported row — 3 sets x 8-12 reps (light back work)
• Lateral raise — 3 sets x 12-15 reps
• Triceps pushdown or overhead extension — 3 sets x 10-15 reps
• Bicep curl — 2 sets x 10-15 reps

Upper B (Pull-Emphasis)

• Pull-up or lat pulldown — 4 sets x 6-10 reps (heavy compound)
• Barbell row or T-bar row — 3 sets x 6-10 reps
• Incline dumbbell bench press — 3 sets x 8-12 reps (light chest)
• Seated cable row — 3 sets x 10-12 reps
• Face pull — 3 sets x 12-20 reps
• Bicep curl (variation) — 3 sets x 10-15 reps
• Triceps isolation — 2 sets x 10-15 reps

Lower A (Squat-Emphasis)

• Back squat or front squat — 4 sets x 5-8 reps (heavy compound)
• Romanian deadlift — 3 sets x 6-10 reps (light hinge)
• Bulgarian split squat or walking lunge — 3 sets x 8-12 reps per leg
• Leg extension — 3 sets x 12-15 reps
• Leg curl — 3 sets x 10-15 reps
• Standing calf raise — 4 sets x 8-15 reps

Lower B (Hinge-Emphasis)

• Conventional or sumo deadlift — 3 sets x 4-6 reps (heavy compound)
• Hip thrust or glute bridge — 4 sets x 8-12 reps
• Front squat or hack squat — 3 sets x 8-12 reps (light squat)
• Stiff-leg deadlift or good morning — 3 sets x 8-12 reps
• Seated leg curl — 3 sets x 10-15 reps
• Seated calf raise — 4 sets x 10-15 reps

Weekly Set Volume by Muscle Group

The weekly hard-set distribution from the template above lands every major muscle group inside the 12-18 set productive window. “Hard set” means within 1-3 reps of failure (RPE 8-9.5). Warm-up sets do not count.

Carryover counts at roughly 50% of the primary muscle activation — so 6 sets of barbell row carryover for biceps equals about 3 effective bicep sets. The numbers above already discount carryover appropriately. For a deeper breakdown of why 12-18 is the productive band, see our body recomp math and timelines piece.

Deload Cadence

Every 4-6 weeks, run a deload week. The deload protocol:

• Same training days, same exercises, same movement patterns.
• 50-60% of the previous week's working weight.
• 3 sets per exercise instead of 4 (or 2 instead of 3).
• Stop sets at RPE 6-7 (4-5 reps in reserve).
• Session duration drops to ~35-40 minutes.

The deload week is not optional during recomp. Helms 2014 noted that natural lifters running 12+ weeks of consecutive overreaching under a deficit lost an average of 2.1% lean mass — most of it accumulated in weeks 8-12 before any deload. The single-most-common pattern in stalled recomp logs is “6 weeks of progress, weeks 7-10 of stagnation, then a deload that revealed the lifter was actually 5-10% stronger than the recent sessions showed.”

How This Pairs with Diet

The training load above sets your minimum calorie floor. With 12-18 hard sets per muscle group across four sessions, you will burn 200-350 calories per session (mostly EPOC and recovery cost) and need 3-4 g/kg bodyweight of carbohydrates on training days to fuel the work. Recovery on rest days needs 0.8-1.0 g/kg bodyweight of fat for hormonal support.

Protein is the constant: 2.2-2.6 g per kg lean body mass per day, every day. See body recomp protein intake for the full distribution math. For a worked 7-day plan that pairs with this training split, the 7-day recomp diet plan handles the meal-by-meal carb and fat targets. Then run the numbers through the body recomposition calculator to lock your weekly targets before week one starts.

When to Switch Splits

Stay on the 4-day upper/lower for the duration of your recomp phase (typically 12-20 weeks). Switching splits mid-recomp resets the strength-progress curve and confounds the data — you will not know if a deload, a diet adjustment, or the new split caused the change. Once you exit the recomp phase into either a focused cut or a focused bulk, that's the appropriate window to swap to a different template (5-day PPL + upper for hypertrophy bulks, or 3-day full-body for short aggressive cuts).

Female lifters running this same split should see our female recomp protocol for cycle-phase adjustments on intensity and rest periods. Lifters over 40 will find the deload cadence likely needs to compress to every 4 weeks rather than every 5-6; the progressive overload guide covers the age-adjusted progression rules.

What Tools and Tracking You Need

Three things are non-negotiable for this split to deliver:

1. A training log. Paper, notes app, or app like Hevy or Strong. You must track weight and reps per set to apply progressive overload. Without the log, you are guessing.
2. A timer. Rest 2-3 minutes between compound sets, 60-90 seconds between isolations. See the evidence on rest between sets.
3. A way to track calories and protein. The macro calculator takes your stats and the training volume above to produce daily targets.

For the income-side math of carving out four 60-minute training sessions per week without your day job eating the schedule, the freelance hourly rate calculator at PayScale Pro handles the training-time tradeoff: how many billable hours you give up per week, and what rate floor you need to make the tradeoff worth it for serious recomp progress.

The Bottom Line

Run a 4-day upper/lower split — Mon/Tue/Thu/Fri — with Upper A push-emphasis, Upper B pull-emphasis, Lower A squat-emphasis, Lower B hinge-emphasis. Hit 12-18 hard sets per muscle group per week, stay 1-3 reps from failure on top sets, deload every 4-6 weeks at 50-60% intensity. Keep cardio capped at 2-3 LISS sessions per week. Pair with 2.2-2.6 g protein per kg lean mass and a 10-15% calorie deficit, and recomp becomes a deterministic process driven by training consistency rather than program-hopping. The split is the foundation. Everything else is finishing work.
