Upper / Lower Split: The 4-Day Step After Full Body

When and how to move from 3× full body to an upper/lower split — templates, volume, progressive overload, and how to keep the week recoverable.

Published · Updated

Scope: Training sequel · Yeh Bro System · training · after beginner full body.

You’ve run full body for a while. The lifts feel less scary. You’re hungry for a bit more volume on chest, back, or legs without living in the gym six days a week. Upper / lower is the boring next step most people should take — not a 7-day “bro split” with zero recovery.

TL;DR

  • Upper / lower = four sessions: Upper A, Lower A, Upper B, Lower B (or two of each).
  • Graduate when 3× full body is consistent for 8–12+ weeks and you want more pattern volume — not because a reel said so.
  • Keep progressive overload and 1–3 reps in reserve (see RPE guide).
  • If life only allows three days, stay on full body — how many days.

When upper / lower earns the slot

Signal Meaning
You’re hitting most planned sessions Consistency exists
Big patterns feel skilled, not terrifying Practice bank is real
Full-body days feel rushed before you finish useful accessories Volume hunger is legitimate
Sleep and food are roughly in place Recovery can absorb four days

Not a reason to switch: boredom after two weeks, influencer periodisation cosplay, or chasing “optimisation” while still missing Monday.

The week shape

Classic recoverable layout:

Day Session
Mon Upper A
Tue Lower A
Wed Walk / off
Thu Upper B
Fri Lower B
Sat–Sun Walk, easy life, optional light conditioning

Swap days to fit work. Keep at least one day between same-pattern hits when you can. Fried for a week? Deload — don’t invent a new split.

Templates (patterns over brand of rack)

Upper A — horizontal bias

Pattern Example Sets × reps
Horizontal push Bench or dumbbell press 3–4 × 5–8
Horizontal pull Row variation 3–4 × 6–10
Vertical push Overhead press 2–3 × 6–10
Vertical pull Pulldown or pull-up progression 2–3 × 6–10
Arms / side delts (optional) Curl + lateral raise 2 × 10–15

Lower A — squat bias

Pattern Example Sets × reps
Squat Back / front / goblet / leg press 3–4 × 5–8
Hinge assist Romanian deadlift 2–3 × 6–10
Single-leg or lunge Split squat 2–3 × 8–12
Carry / core Farmer or suitcase carry 2–3 rounds

Upper B — vertical / pump bias

Pattern Example Sets × reps
Vertical push Overhead press (main) 3–4 × 5–8
Vertical pull Pull-up / pulldown 3–4 × 5–8
Horizontal push (lighter) Incline or machine 2–3 × 8–12
Horizontal pull (lighter) Cable / chest-supported 2–3 × 8–12
Rear delt / arm finish Face pull + triceps 2 × 10–15

Lower B — hinge bias

Pattern Example Sets × reps
Hinge Trap-bar or conventional (conservative) 3 × 3–6
Squat assist Leg press or hack 2–3 × 8–12
Ham / glute accessory Leg curl or hip thrust 2–3 × 8–12
Calves / core As needed 2–3 × 8–15

Warm up like an adult — warmup before lifting. Leave ego sets for Instagram, not the logbook.

Volume without frying yourself

  • Most work sets: stop with reps in reserve — RPE / RIR.
  • Progress load or reps on the main lifts first; accessories can coast.
  • Four hard days plus daily redline cardio is how intermediates stall. Walk instead — walking for lifters.

Food and recovery still matter more than the split

A prettier calendar doesn’t fix under-eating protein or four-hour sleep:

Soft close

Full body builds the skill. Upper / lower buys volume when you’ve earned it. Ready for more sets without frying? Upper / lower advanced volume. Keep the week boring enough that you’ll still be training in twelve months — that’s the Yeh Bro System bar.
