4-day split
4 day upper lower workout split
Upper Lower is the default next step after full body because it preserves frequency while giving each session more room.
This version uses heavier upper/lower days followed by volume upper/lower days.
Best fit
Lifters who want each muscle trained twice per week without a six-day schedule.
People who cannot recover from two lower-body days per week.
Train upper and lower body twice per week.
Use heavier ranges early in the week.
Use volume days for hypertrophy and weak points.
Keep deadlift volume controlled.
Weekly schedule
Put the hard sessions where recovery can support them.
- Monday: Upper Strength
- Tuesday: Lower Strength
- Thursday: Upper Volume
- Friday: Lower Volume
Program table
Exact sets, reps, rest, and intent.
Every exercise links to its RepStack form guide. Keep the movement names consistent in your log so your history, PRs, and next-session targets stay usable.
Upper Strength

|---|---|---|---|---|
| Barbell Bench Press | 4 | 4-6 | 3 min | Main upper strength slot. |
| Bent Over Barbell Row | 4 | 5-8 | 2-3 min | Treat rows like a primary lift. |
| Standing Military Press | 3 | 5-8 | 2 min | Leave one rep in reserve. |
| Pullups | 3 | 6-10 | 2 min | Use assistance or load to stay in range. |

Progression
The plan is only useful if next week is measurable.
Progression rule
Use narrower rep ranges on strength days and wider ranges on volume days so the load jumps fit the lift.
Use double progression unless a lift specifies otherwise: add reps inside the range first, then add load after every working set reaches the top. If a lift misses the floor twice, reduce load or volume instead of forcing the same target again.
- Compounds: add load only after all sets hit the top of the range.
- Dumbbells and isolations: use wider rep ranges because jumps are larger.
- Log the same exercise name every week so progress stays readable.
Swap logic
If lower recovery is poor, swap deadlift volume for RDLs or leg curls before abandoning the whole split.
Do not swap movements just because a session feels boring. Swap when equipment, pain-free range, skill, or recovery blocks the programmed job.
What to do after 8-12 weeks
Repeat if attendance and e1RM trends are stable. Move to PPL only if you can consistently train more days.
If strength, reps, and attendance are all moving, repeat the block with small adjustments. If only one lift is stuck, fix that lift. If everything is stuck, change recovery, volume, or program structure.

FAQ
Fast answers
Who should run 4 day upper lower workout split?
Lifters who want each muscle trained twice per week without a six-day schedule.
Can I change exercises?
Yes, but preserve the pattern. Swap a horizontal press for another horizontal press, a squat pattern for another squat pattern, and keep the log name consistent.
How should I track this in RepStack?
Create the program as saved days, log every working set, and let the repeated history drive next-session targets.
