4-Day Workout Plan: Complete 2026 Guide
Looking for a 4-day workout plan that actually works? This guide shows you the best 4-day splits for hypertrophy and strength, with examples and a free AI generator.
Why 4 days a week is the ideal frequency
A 4-day workout plan is the gold standard for intermediate lifters. Each muscle group gets trained twice per week (optimal hypertrophy frequency) while you keep 3 full recovery days.
Optimal 2x/week frequency
Schoenfeld's 2016 meta-analysis confirms that training each muscle twice per week produces more hypertrophy than once.
Adequate recovery
3 rest days per week let your CNS and muscles fully recover.
Manageable per-session volume
Shorter, focused 60-75 min sessions with higher per-muscle intensity.
Flexible scheduling
Miss a day and just shift the plan by 24 hours. Much easier to stick with than a 6-day split.
The 3 best 4-day splits
There's no universal 4-day split. Here are the 3 most effective and science-backed options.
1. Upper / Lower
Mon Upper A · Tue Lower A · Thu Upper B · Fri Lower B
Pros
- 2x/week frequency, optimal for hypertrophy
- Simple to program
- Excellent recovery
- Works for late-beginner to intermediate
Cons
- ✗Upper days can run 75+ minutes
- ✗Less volume per muscle than a bro split
Best for: The #1 recommendation for hypertrophy and strength.
2. Push / Pull + Full Body + Weak Point
Mon Push · Tue Pull · Thu Full Body · Fri Weak Point
Pros
- Shorter, focused sessions
- Lets you emphasize a weak point
- Varied stimulus
Cons
- ✗Full body day can be heavy
- ✗Harder to program
Best for: Ideal if you have an obvious weak point.
3. 4-Day Bro Split
Mon Chest + Tri · Tue Back + Bi · Thu Legs · Fri Shoulders + Core
Pros
- Very high per-muscle volume
- Focused, intense sessions
Cons
- ✗1x/week frequency is suboptimal
- ✗Low tolerance for missed sessions
Best for: Only for very advanced lifters with high volume tolerance.

| Conventional deadlift | 4 | 5 | 2 |
| Front squat (or hack squat) | 3 | 8 | 2 |
| Dumbbell walking lunge | 3 | 10 per leg | 1 |
| Seated leg curl | 3 | 12 | 1 |
| Seated calf raise | 4 | 15 | 1 |
| Machine crunch | 3 | 15 | 1 |
Weekly volume: MEV, MAV, MRV
Weekly set ranges per muscle group:
| Muscle | MEV | MAV | MRV |
|---|---|---|---|
| Chest | 8-10 | 12-16 | 18-22 |
| Back | 10-12 | 14-18 | 20-25 |
| Side delts | 8 | 12-16 | 20 |
| Biceps | 6-8 | 10-14 | 16-20 |
| Triceps | 6-8 | 10-14 | 16-20 |
| Quads | 8-10 | 12-16 | 18-22 |
| Hamstrings | 6-8 | 10-14 | 14-18 |
| Calves | 8 | 12-16 | 20 |

Start at MEV, add 1-2 sets per week toward MAV, then deload.
Who should use a 4-day plan?
Not every plan fits every lifter.
Beginners (0-6 months)
Borderline
Works, but a 3-day full body plan is usually more efficient.
Intermediates (6-24 months)
Ideal fit
The 4-day split is the #1 pick here.
Advanced (2+ years)
Great fit
4 days still works, especially with a weak-point approach.
3 days vs 4 days vs 5-6 days
| Feature | 3 days (Full Body) | 4 days (UL) | 5-6 days (PPL) |
|---|---|---|---|
| Frequency per muscle | 3x/week | 2x/week (optimal) | 2x/week |
| Weekly time | ≈3 h | ≈4-5 h | ≈6-7 h |
| Volume per muscle | Low-Medium | Medium-High | Very High |
| Recovery | Excellent | Good | Tight |
| Best for | Beginners / busy lifters | Intermediates | Advanced |
5 common 4-day split mistakes
Too much volume, too fast
Start at MEV and build up.
Rest periods too short
Use 2-4 min on compounds.
Changing program every 4 weeks
Keep it for 8-12 weeks.
Skipping deloads
Every 4-6 weeks, cut volume 40-50%.
Not tracking weights
Log every set or use an app.

Frequently Asked Questions
How long to see results with a 4-day workout plan?
Strength gains show after 3-4 weeks of consistent training. Visible muscle growth takes 8-12 weeks combined with a 200-400 kcal surplus and 7-9 hours of sleep. The 2x per muscle frequency you get from a 4-day split is the main reason it outperforms a 1x/week bro split.
4 days or 3 days training — what's better for beginners?
For absolute beginners (0-6 months), a 3-day full body plan is usually better because it hits high frequency on the compound lifts. A 4-day plan (upper/lower or push/pull) is ideal for intermediates with 6+ months of experience: more volume, better specialization, still enough recovery.
Upper/lower, push/pull/legs or bro split — which 4-day split?
Upper/lower is the #1 choice for most intermediates: 2x/week frequency per muscle, simple programming, excellent recovery. Push/pull + full body/weak point is more flexible and great if you have obvious weak points. A 4-day bro split only works for very advanced lifters.
Can I use a 4-day plan to lose weight?
Yes. The split stays the same, but reduce total volume by 10-15% and keep loads high to preserve muscle. Add 2-3 light cardio sessions (LISS, 30-45 min) on rest days. A 300-500 kcal deficit with 1.8-2.2 g protein/kg bodyweight is the baseline.
How much rest between sets?
Compound lifts with 6-8 reps: 2-4 minutes. Isolation work with 10-15 reps: 60-90 seconds. Shorter rests on big compounds sabotage the next set.
