The Best 4-Day Workout Split
Introduction
When it comes to building muscle and strength, the structure of your workout routine plays a crucial role. The 4-day workout split is one of the most popular and effective training schedules for those looking to make serious progress without overtraining. With the right balance of intensity, recovery, and variety, a 4-day split allows for targeted muscle development, improving both strength and hypertrophy (muscle growth).
This guide will explore the best 4-day workout split, including detailed plans for each training day, tips on optimizing your workout routine, and how to track your progress. Whether you’re a beginner or an experienced lifter, this plan will help you maximize your results and stay on track for long-term success.
Why Choose a 4-Day Workout Split?
Benefits of a 4-Day Split
A 4-day workout split is the perfect middle ground for those looking to train efficiently without spending hours in the gym. Here are some of the key benefits:
Balanced Recovery: With four workout days, you still get ample rest between muscle groups, allowing for muscle recovery and growth.
Targeted Training: A 4-day split allows you to focus on specific muscle groups, ensuring balanced development and preventing overtraining of any single area.
Flexibility: It’s a schedule that works well for those with a busy lifestyle, offering the flexibility to adjust workout days as needed.
Increased Intensity: With more time to focus on each muscle group, you can increase the intensity and volume of your workouts, leading to better gains over time.
How a 4-Day Split Fits Into a Weekly Schedule
A typical 4-day workout split can be scheduled with one rest day in between each workout. Here’s an example layout:
Monday: Upper Body – Push Focus (Chest, Shoulders, Triceps)

Tuesday: Lower Body – Quads and Glutes Focus
Wednesday: Rest or Active Recovery
Thursday: Upper Body – Pull Focus (Back, Biceps)
Friday: Lower Body – Hamstrings and Calves Focus
Saturday: Rest or Active Recovery
Sunday: Optional Rest or Cardio
By structuring your workout days this way, you allow your body to recover between sessions, preventing burnout while maximizing muscle growth.
Anatomy of a 4-Day Split
To design an effective 4-day workout split, it’s important to understand the structure of your muscles and how to divide them logically. There are a few different ways to split up your workout routine, depending on your goals and preference.
Upper/Lower Split
In an upper/lower split, you train your upper body on one day and your lower body on the other. This split is simple, easy to follow, and effective for both beginners and advanced lifters. It allows for balanced focus on both upper and lower body muscle groups.
Upper Body: Targets chest, back, shoulders, arms (biceps, triceps)
Lower Body: Targets quads, hamstrings, glutes, calves
Push/Pull Split
The push/pull split focuses on exercises that target “pushing” muscles and “pulling” muscles. This split ensures that you hit all major muscle groups while promoting recovery between sessions.
Push Day: Focuses on chest, shoulders, and triceps (muscles used for pushing)
Pull Day: Focuses on back, biceps, and forearms (muscles used for pulling)
Full-Body Routine
While full-body routines typically involve training three days per week, incorporating elements of full-body training into a 4-day split can be effective. This approach helps maintain balance and engage multiple muscle groups on each workout day.
The Best 4-Day Workout Split: Breakdown
Now that you understand the benefits and anatomy of the 4-day split, let’s break down an effective plan for each workout day.
Day 1: Upper Body – Push Focus (Chest, Shoulders, Triceps)
This workout will focus on pushing movements that activate the chest, shoulders, and triceps, helping to build upper body strength and muscle mass.
Barbell Bench Press – 4 sets of 6-8 reps
Focus on maximal strength for the chest. Perform the exercise slowly and with controlled movements.
Dumbbell Shoulder Press – 4 sets of 8-10 reps
Targets the shoulders, particularly the anterior deltoids. Press upward and avoid arching your back.
Incline Dumbbell Press – 3 sets of 10-12 reps
Hits the upper chest and front deltoids for a more well-rounded upper body.

Tricep Dips – 3 sets to failure
If you’re aiming for tricep hypertrophy, make sure to go deep in the movement for full range of motion.
Lateral Raises – 3 sets of 12-15 reps
Targets the lateral deltoids, helping to build width in the shoulders.
Tricep Rope Pushdowns – 3 sets of 10-12 reps
Finish off your push day with tricep rope pushdowns for maximum muscle engagement.
Day 2: Lower Body – Quads and Glutes Focus
The lower body workout focuses on compound movements that target the quadriceps and glutes while also incorporating hamstrings and calves.
Squats – 4 sets of 6-8 reps
Squats are the king of leg exercises, targeting the quads and glutes. Focus on depth and proper form.
Leg Press – 4 sets of 8-10 reps
A great alternative to squats that isolates the quads.
Bulgarian Split Squats – 3 sets of 10 reps per leg
This exercise targets the quads and glutes, with an emphasis on balance and unilateral strength.
Hip Thrusts – 3 sets of 10-12 reps
Perfect for isolating the glutes, helping to build size and strength.
Calf Raises – 4 sets of 12-15 reps
Finish off your leg day with calf raises to target the lower leg muscles.
Day 3: Upper Body – Pull Focus (Back, Biceps)
This workout targets the back, biceps, and forearms with pulling movements that maximize muscle engagement and strength.
Deadlifts – 4 sets of 4-6 reps
A compound movement that works the entire back, posterior chain, and core. Prioritize form to avoid injury.
Pull-Ups – 3 sets to failure
Great for building width in the upper back and improving lat strength.
Barbell Rows – 4 sets of 8-10 reps
Engage the lats, traps, and rear delts for overall back thickness.
Seated Cable Rows – 3 sets of 10-12 reps
Isolates the middle back and works the lats for complete muscle development.
Barbell or Dumbbell Bicep Curls – 3 sets of 10-12 reps
Focus on building the biceps by curling the barbell or dumbbells in a slow and controlled manner.
Hammer Curls – 3 sets of 12-15 reps
A variation of bicep curls that also works the forearms and brachialis muscle.
Day 4: Lower Body – Hamstrings and Calves Focus
The final leg day of the week will focus on hamstring and calf development, giving your lower body muscles a balanced workout.
Romanian Deadlifts – 4 sets of 6-8 reps
A key exercise for building hamstring and glute strength while improving flexibility.

Key Principles for Success in Your 4-Day Split
Progressive Overload
One of the key principles for muscle growth is progressive overload—gradually increasing the weight, reps, or intensity of your workouts to keep challenging your muscles.
Proper Form and Technique
Ensure you maintain proper form during all exercises to avoid injuries and maximize muscle engagement.
Nutrition for Muscle Growth
Consume a balanced diet with adequate protein intake (1.6-2.2 grams of protein per kilogram of body weight) and enough calories to support muscle growth.
Rest and Recovery
Allow 48-72 hours of rest between workouts targeting the same muscle group. Proper rest, including sleep, is crucial for muscle repair and growth.
Common Mistakes to Avoid
Skipping Warm-Ups: Never skip your warm-up. It’s essential for injury prevention and performance.
Not Tracking Progress: Keep a workout log to track weights, sets, and reps to ensure you’re progressing.
Overtraining: Ensure adequate recovery time between workouts and avoid pushing yourself too hard.
Neglecting Stretching: Stretching improves flexibility and reduces muscle tightness, aiding in recovery.
How to Track Your Progress
Tracking your progress can be done through the following methods:
Workout Journal: Write down sets, reps, and weights lifted.
Body Measurements: Measure your arms, chest, waist, and legs regularly.
Progress Photos: Take pictures to visually track changes in muscle definition and size.
Strength Tracking: Note improvements in strength, like lifting heavier weights or increasing reps.
FAQs
Q1: How often should I do the 4-day split?
Four days per week is ideal, but depending on your recovery and goals, you can adjust to fit your schedule.
Q2: Is this split good for beginners?
