What is Upper-Lower Split?

An upper-lower split is a workout split that divides your training week into just two categories: upper-body sessions and lower-body sessions. On an upper day you train everything above the waist — chest, back, shoulders, biceps, triceps, and often core; on a lower day you train everything from the hips down — quads, hamstrings, glutes, and calves. Most lifters run it four days a week (upper, lower, upper, lower, with rest days spaced around it), though 2-, 3-, and 5-day versions exist for different schedules. It's often the first split lifters graduate to after starting with full-body training, since it keeps the same two-category simplicity while allowing more exercises and sets per muscle group each session.

How it works

The upper-lower split works by grouping muscles so that a hard lower-body session (which taxes your central nervous system and recovery through squats and deadlifts) doesn't collide with a hard upper-body session the next day. Running two upper and two lower sessions across a week — say Monday/Thursday upper and Tuesday/Friday lower — gives each muscle group roughly 72 hours of recovery before it's trained again, which lands in the frequency range research associates with better strength and hypertrophy outcomes than training each muscle only once a week. Because each session covers a whole region rather than a single body part, you also get built-in variety within the week: an upper day might open with a heavy bench press for strength, then move into rows, presses, and arm work for size, while the following upper session emphasizes different exercise variations to hit the same muscles from new angles.

Types

Worked example

A standard 4-day upper-lower week, with each muscle group trained on two non-consecutive days.

Each region gets 2 sessions with 3 rest days spread through the week — enough spacing to recover between the same muscle groups.

Upper-lower split vs full-body workout

Both hit each muscle roughly twice a week — pick upper-lower if you have a 4th training day to spare and want more volume per region, or full-body if 3 days is your ceiling and you'd rather every session cover the whole body.

By goal

• Beginners: A 3- or 4-day upper-lower split is one of the most reliable starting structures — simple to follow with clear recovery days built in and enough frequency to learn the main lifts quickly.
• Intermediate/advanced lifters: Add a 5th day for lagging muscle groups while keeping the two core upper and two core lower sessions intact, or increase sets per session as recovery capacity improves.
• Time-limited lifters: A 2-day upper-lower week (one upper, one lower) still trains every major muscle group weekly if 4 days isn't realistic, at roughly maintenance-level frequency.
• Strength-focused lifters: Anchor each lower day with a squat or deadlift variation and each upper day with a bench or overhead press variation, then build accessories around those two main lifts per session.

Common misconceptions

• "Upper-lower only works as a 4-day plan." 2-, 3-, and 5-day versions all exist — 4 days is simply the most common and most-studied version.
• "Lower days are just squats and deadlifts." A full lower session also covers hamstrings, glutes, and calves directly through movements like leg curls, hip thrusts, and calf raises — not only the two big barbell lifts.
• "You need to train upper and lower on alternating days with no rest." Most 4-day templates build in 1-3 rest days per week (e.g. upper/lower/rest/upper/lower) rather than four consecutive training days.
• "Upper-lower can't build as much size as a bro split." At equal weekly volume, upper-lower splits produce comparable hypertrophy to single-muscle-per-day splits — the extra frequency compensates for smaller volume per individual session.

Upper-Lower Split FAQ

What is an upper-lower split?

An upper-lower split is a workout split that alternates upper-body training days with lower-body training days, usually four times a week, so each half of the body trains about twice weekly.

How many days a week is upper-lower?

Four days is the most common version (2 upper, 2 lower), though 2-, 3-, and 5-day variations all exist depending on how much time you can train.

Is upper-lower better than push-pull-legs?

Neither is objectively better — both typically train each muscle group about twice a week; upper-lower fits a 4-day schedule while PPL is built for 3 or 6 days.

What muscles do you train on lower day?

Lower day trains quads, hamstrings, glutes, and calves through movements like squats, deadlifts, lunges, and leg curls, plus often direct core work.

Can beginners use an upper-lower split?

Yes — it's one of the most recommended structures for beginners because it's simple, trains everything twice weekly, and fits a realistic 3-4 day schedule.

What exercises go on an upper-lower split?

Upper days typically include a bench or overhead press, a row or pull-up, and shoulder/arm accessories; lower days typically include a squat or deadlift variation, a hip-hinge movement, and calf or core work.

How much rest between upper-lower sessions?

A standard 4-day template spaces the two upper days and two lower days about 3-4 days apart from their same-region counterpart (e.g. upper on Monday and Thursday), giving roughly 72 hours of recovery per muscle group.
