- An upper/lower split trains each muscle twice a week across four sessions.
- Each session stays focused, so you can push hard without a marathon workout.
- It suits people with three to five training days who want strength and muscle.
- Plan runs and conditioning around it so hard leg days do not collide.
What an upper/lower split is
The idea is simple. On upper days you train chest, back, shoulders and arms. On lower days you train quads, hamstrings, glutes, calves and usually some core work. Most people run it over four days, which means every muscle group is trained twice a week, a frequency that research and coaching experience both support for strength and muscle growth.
It sits between a full body routine, where you train everything every session, and a body part split, where each muscle gets one big session a week. You get more focus per session than full body training and more frequency than a traditional chest day, back day approach.
Because lower body sessions are the most tiring, separating them from upper sessions also gives your legs a clear break before they are asked to work hard again. That matters if you also run, cycle or play sport at the weekend.
Why it works so well for most people
- Twice-weekly frequency: each muscle gets two chances a week to be trained hard, and the weekly work is spread out so no single session is exhausting.
- Manageable sessions: four to six exercises per day is enough, which keeps sessions around 45 to 70 minutes.
- Built-in recovery: your lower body rests on upper days and vice versa, so you can train on consecutive days.
- Room for strength and size: many people run one heavier, lower rep day and one lighter, higher rep day for each half.
It is also very easy to understand. You always know what today is for, which helps on the evenings when motivation is low and you just need to turn up and follow the plan.
A sample four-day week
A classic layout is Monday upper, Tuesday lower, Thursday upper and Friday lower, with Wednesday and the weekend off or used for walking, easy cardio or sport. The sessions might look like this (sets x reps):
- Upper A: bench press 4 x 5, barbell row 4 x 6, overhead press 3 x 8, pull-ups or pulldowns 3 x 8, face pulls 2 x 15.
- Lower A: back squat 4 x 5, Romanian deadlift 3 x 8, walking lunges 2 x 10 each leg, calf raises 3 x 12, plank 3 x 30 to 45 seconds.
- Upper B: incline dumbbell press 3 x 10, chest-supported row 3 x 10, dumbbell shoulder press 3 x 10, chin-ups 3 sets of as many good reps as you can, curls and triceps extensions 2 x 12 each.
- Lower B: trap bar or conventional deadlift 3 x 5, Bulgarian split squat 3 x 8 each leg, leg curl or Nordic curl 3 x 8, hip thrust 3 x 10, Pallof press 2 x 12 each side.

Three-day and five-day versions
Not everyone can train four days a week. With three days, you can alternate: week one is upper, lower, upper; week two is lower, upper, lower. Each muscle is then trained three times every fortnight, which still works well, particularly for beginners and busy parents.
With five days, you might add a session for conditioning, a weak point or a HYROX-style engine workout. The upper/lower core stays the same, and the extra day fills a gap rather than piling more heavy lifting onto tired muscles.
If you can only train twice a week, full body sessions are usually the better fit. Our comparison of full body vs split routines walks through that decision.
Fitting running and conditioning around it
Hybrid athletes and HYROX competitors often combine an upper/lower split with running. The main rule is to avoid a hard run the day before a heavy lower session, and to avoid heavy squats the day before a key run. Upper days are the natural partner for runs, because your legs are not under heavy load.
A common pattern is lower body strength early in the week, an easy run alongside the first upper day, a harder run or engine session midweek, then the second lower session later in the week with at least a day's gap before a long run. It is not perfect, but it limits the interference between the two.
In the final weeks before a HYROX event, the second lower day can lean towards lunges, sled work and wall balls, as long as the heavy strength base stays in place.
Common mistakes
- Cramming ten exercises into each day because there are only two session types to choose from.
- Neglecting the hamstrings and lower back by doing only squats and leg extensions.
- Doing lots of pressing and very little pulling on upper days, which tends to leave shoulders cranky.
- Skipping the second lower day whenever life gets busy, so legs end up trained once a week.
Keep upper days roughly balanced between pushing and pulling, and make sure each lower day includes both a knee-dominant movement like a squat and a hip-dominant one like a hinge.
Upper/lower in a class setting
If you prefer training with a coach and a group, the structure translates well. The Lycan Strength timetable is built around Full Body, Upper and Lower classes, with Upper on Tuesday and Wednesday and Lower on Thursday, so members can follow an upper and lower pattern across the week while coaches scale each movement to the person. You can see how the days fall on the class timetable.
Whether you follow it in classes or on your own, give any split at least eight weeks before judging it. Consistency with a decent plan beats constant switching between perfect ones.

Questions
Is an upper/lower split good for beginners?
Yes, especially the three or four day version. Complete beginners often do just as well on full body sessions, but upper/lower is a sound choice once you can train four days a week.
Can I do upper and lower sessions on consecutive days?
Yes. Different muscles are trained each day, so back-to-back sessions work well. Most people take a rest day after two or three days in a row.
Is upper/lower better than push/pull/legs?
Neither is clearly better. Push/pull/legs usually needs six days to train each muscle twice, while upper/lower does it in four, which suits most schedules better.
How long should an upper/lower session take?
Around 45 to 70 minutes including a warm-up is typical, with four to six exercises.
