# 4-Day Upper/Lower Split: A Complete Weekly Plan > Updated: 2026-09-01 · Source: https://dorsi.ai/workout-plans/4-day-upper-lower-split Follow a four-day upper/lower split with two distinct upper sessions, two lower sessions, progression rules, and practical recovery adjustments. Train each major movement pattern twice per week while separating the harder squat, hinge, press, and pull exposures across four repeatable sessions. ## Four days should buy you better distribution A four-day upper/lower split is not automatically superior to a three-day full-body plan. Its advantage is room. You can give the main squat, hinge, press, and pull their own emphasis without asking every session to cover the whole body. The schedule also gives each major muscle group two planned exposures while leaving space for recovery. This guide provides the exact four-day program. The broader [workout-split guide](/workout-plans/workout-split) helps you choose among schedules, while the general upper/lower guide covers the underlying structure. Here, the exercise order, dose, and progression are already defined so you can run the week rather than keep comparing templates. ## Keep the second exposure different, not random Upper B and Lower B are not novelty days. They repeat the same movement categories with a different emphasis and usually a lighter secondary dose. That makes weekly progress measurable without forcing the same joints and lifts through identical work twice. Record completed sets, repetitions, load, and effort. If one session repeatedly disappears, the answer is usually a lower-frequency plan, not a growing pile of make-up workouts. Dorsi can use completed work and changing availability when organizing what comes next; the [personalized planning page](/personalized-workout-plan) shows how those details shape the next plan. This plan is for generally healthy adults. Sharp pain, fainting, chest pain, unusual shortness of breath, or persistent loss of normal function calls for appropriate medical guidance rather than another programming adjustment. ## FAQ ### Is a four-day upper/lower split effective? Yes. It gives every major movement pattern two weekly exposures while leaving three days without lifting. The split is effective when those four sessions fit your schedule and the second upper and lower days remain productive rather than becoming recovery tests. ### Should the two upper and two lower days be identical? No. Keep the movement jobs consistent, but change the emphasis. This plan makes the first upper day horizontal-press focused, the second vertical-press focused, the first lower day squat focused, and the second hinge focused. ### Is upper/lower better than push/pull/legs? It is usually easier to fit into four days. Push/pull/legs becomes most symmetrical at six sessions, while upper/lower trains each half twice with fewer weekly appointments. The better split is the one that holds the needed work without repeated missed days.
