4 Day Workout Split Reddit: 7 Practical Options Compared

Search "4 day workout split reddit" and you will usually see the same question in different forms: which split is simple enough to stick with, but smart enough to keep you progressing? The honest answer is that there is no single perfect layout. The best four-day plan is the one you can recover from, repeat, and actually enjoy long enough to see results.

How to compare four-day splits

There is no single Reddit-approved split. These are seven editorial options for someone comparing four-day schedules, not a survey or ranking of Reddit votes. Frequency research supports choosing a schedule that distributes a manageable weekly workload. For technique basics, see the lifting principles guide.

1. Upper/Lower Split

Upper/lower is a straightforward starting option: upper Monday, lower Tuesday, rest Wednesday, upper Thursday, lower Friday, then the weekend off. Each region gets two planned exposures. Adjust exercise selection and sets to your experience.

Include presses and pulls on upper days, plus squats, hinges and any relevant accessories on lower days. Keep the work manageable enough to repeat. The Setgraph training guides offer more examples.

2. Upper/Lower A/B Split

Keep the same Monday/Tuesday/Thursday/Friday calendar, but use Upper A, Lower A, Upper B and Lower B. For example, A can emphasize bench and squat practice while B emphasizes a different press, pull and hinge. Both days still cover their region.

This lets you vary exercise emphasis without adding days. It is an organizational choice rather than a proven superior split. In a 2024 review of split and full-body training, matched-volume routines produced similar strength and muscle-growth outcomes.

3. Push, Pull, Legs Plus Upper

Try push Monday, pull Tuesday, legs Thursday and upper Saturday, with the other days off. This gives pressing and pulling muscles two planned exposures but legs only one dedicated day; it is an upper-body-emphasis choice.

Use the upper day for manageable pressing and pulling work, rather than repeating every exercise from the first two days. If lower-body development is an equal priority, upper/lower may distribute your work more evenly.

4. Full-Body A/B Rotation

An example is A Monday, B Tuesday, A Thursday and B Saturday, with Wednesday, Friday and Sunday off. Both sessions include upper and lower work, but use fewer sets per movement than a three-day full-body program; alternating squat- and hinge-emphasis sessions can help manage the consecutive days.

Four full-body sessions can be useful when you prefer smaller amounts of work per session. They do not guarantee shorter workouts or better recovery. Count the week’s total sets and adjust the Monday/Tuesday pair if fatigue carries over. A workout log can make that comparison easier.

5. Powerbuilding Split

Powerbuilding combines strength practice with muscle-building accessories. A four-day example is upper strength Monday, lower strength Tuesday, upper moderate-rep Thursday and lower moderate-rep Friday. Keep heavy work focused on the lifts you want to improve.

What makes it work is that it gives priority to the lifts that matter most to you. If your goal is to add weight to the bar, powerbuilding keeps those compounds front and center. If your goal is to look more muscular, the accessory work fills in the gaps. The tradeoff is balancing practice of heavier lifts with enough accessory work for your goals. Too much of either can make sessions long or difficult to recover from. Keep the main lifts stable for several weeks before deciding whether the split is helping or just feeling hard.

6. Body-Part Split

A body-part example is chest Monday, back Tuesday, legs Thursday and shoulders plus arms Saturday, with the other days off. Each region has a dedicated session, although arms and shoulders also work during presses and pulls.

This layout concentrates direct work into fewer exposures per muscle. Keep the number of exercises and sets realistic, especially late in the session. Preference and recoverable workload matter more than the name of the split.

7. Upper/Lower With a Weak-Point Emphasis

Keep four sessions: upper Monday, lower Tuesday, upper Thursday and lower Friday. Place a small amount of priority work at the start of one existing session and reduce a less-important accessory to make room. Do not add a separate fifth day.

For example, begin Thursday upper with two sets of lateral raises if shoulders are the priority, then remove two sets from another shoulder accessory. Reassess the whole week before adding volume, including indirect work from compounds.

How to choose the right one

Choose by the days you can attend, the session length you can sustain and the work you recover from. A novice may prefer two or three simpler sessions; four days is an option, not an achievement level.

Use this quick filter:

• Upper/lower: a balanced four-day starting structure.

• A/B or powerbuilding: more deliberate differences in exercise or loading emphasis.

• PPL plus upper: prioritize the upper body while accepting one dedicated leg day.

• Full-body A/B: distribute sets broadly and manage consecutive-day overlap.

• Body-part or weak-point emphasis: choose focused work without exceeding your recoverable weekly total.

For an example of a simpler schedule, compare these options with three-day full-body routines.

How to make any 4-day split work

Keep your main lifts mostly stable for several weeks so you can compare sets, reps and effort. Change sooner if a movement causes pain or the schedule is unworkable. When progress stalls, review technique, rest, load jumps and recovery, then change one variable at a time.

A simple rule set helps more than a fancy template:

• Keep the first one or two exercises on each day consistent.

• Add reps before adding weight when the movement is still new.

• Use accessories to support the main lifts, not to bury you in junk volume.

• Write down what you did, then compare it to last week.

If you like keeping a digital logbook, pairing your plan with a workout tracker gym log app is an easy way to reduce guesswork.

The bottom line

Start with the layout that fits your actual week. Upper/lower is a useful default to compare against, while the other options change emphasis and workload distribution. Keep a log and judge the plan by repeatability and progress rather than Reddit popularity.
