4-Day Workout Plan
An upper/lower split that trains every muscle twice per week — the sweet spot for strength and hypertrophy.

Level
Four days per week is the most popular training frequency for intermediate lifters — and for good reason. It provides enough volume and frequency to drive continuous progress without overwhelming recovery. The upper/lower split is the gold standard for 4-day programming because it naturally balances pushing, pulling, and leg work across the week.
Compared to a 3-day program, the extra day lets you add more exercise variety and more sets per muscle group. Compared to a 5-6 day split, it gives you three full rest days for recovery, life, and active recovery. For most lifters, 4 days is the point of diminishing returns — additional training days add minimal extra growth.
The program below alternates between upper and lower body days with strategic exercise variation between the two upper days and two lower days. Each muscle group gets trained twice per week, which research consistently identifies as the optimal frequency for hypertrophy.
Sample workouts

| Dumbbell Row | 3 | 10-12 | 90 sec |
| Lateral Raises | 3 | 12-15 | 60 sec |
| Tricep Dips | 3 | 8-12 | 60 sec |
Day 2: Lower Body A
Squat Focus — Quads, Glutes
| Exercise | Sets | Reps | Rest |
|---|---|---|---|
| Barbell Back SquatMain lift — progressive overload | 4 | 6-10 | 3 min |
| Walking Lunges | 3 | 10-12 each | 2 min |
| Leg Curl | 3 | 12-15 | 90 sec |
| Standing Calf Raises | 4 | 12-15 | 60 sec |
| Plank | 3 | 45-60 sec | 60 sec |
Day 3: Upper Body B

Day 4: Lower Body B
Hinge Focus — Hamstrings, Glutes
| Exercise | Sets | Reps | Rest |
|---|---|---|---|
| Barbell DeadliftMain lift — quality reps | 4 | 4-8 | 3 min |
| Leg Press | 3 | 10-12 | 2 min |
| Hip Thrust | 3 | 10-15 | 90 sec |

| Hanging Leg Raises | 3 | 12-15 | 60 sec |
Why this program works
Optimal 2x/week muscle frequency backed by hypertrophy research
More volume per muscle group than a 3-day program — drives faster progress
Three full rest days per week for recovery and life balance
Upper/lower split naturally balances push and pull movements
Exercise variation between A and B days prevents staleness and overuse
Scalable — easy to add volume as you advance without changing the structure
Tips for success
- Train Mon/Tue, rest Wed, train Thu/Fri. This gives you a rest day mid-week and a full weekend off.
- Day 1 and Day 3 use different main lifts (bench vs row) — do not swap them or you will over-train one pattern.
- Use RPE (Rate of Perceived Exertion) — main lifts should be RPE 7-8, accessories RPE 8-9.
- If you miss a day, shift the remaining days forward rather than doubling up. Recovery matters more than scheduling.
- Every 4 weeks, take a deload week: same exercises at 60% of your working weight for 2-3 sets each.

Frequently asked questions
Is a 4-day split better than a 5-day or 6-day split?
For most people, yes. Research shows diminishing returns beyond 2x/week per muscle group. A 4-day split provides this frequency while leaving more time for recovery. Higher-frequency splits (PPL 6-day) add convenience for scheduling but not meaningfully more muscle growth for most lifters.
Can beginners use a 4-day program?
Beginners are better served by a 3-day full-body program for their first 3-6 months. The simpler structure, lower total volume, and more rest days are ideal while learning movement patterns and building work capacity. Switch to 4 days once progress stalls on a 3-day program.
Should I do upper or lower first in the week?
Start with whatever you want to prioritize. If bench and shoulders are lagging, start with upper. If your squat and deadlift need work, start with lower. Most people start with upper because chest day is more popular, but it does not matter physiologically.
What if I can only train 3 days one week?
Drop one of the B days (whichever muscle group you trained most recently). So if you did Upper A on Monday and Lower A on Tuesday, skip Upper B and do Lower B on Thursday. You will still hit every muscle group at least once that week.
How do I progress on a 4-day plan?
Use double progression: pick a rep range (e.g., 3x6-10), start at the low end with a given weight, and add reps each week until you hit the top of the range for all sets. Then increase weight 5 lbs and drop back to the low end. This works reliably for intermediate lifters.
