Best Routine to Build Muscle and Lose Fat (4-Day Split)

What is the best workout routine to gain muscle and lose fat?

The best routine for gaining muscle while losing fat is a structured mix of progressive strength training, a small amount of targeted cardio, and recovery that’s consistent enough to repeat week after week. Most people do best with 3–5 lifting sessions per week built around compound movements, paired with a modest calorie deficit (or maintenance on training days) and high protein.

A simple weekly routine that works

Lift 3–5 days/week: Prioritize compound lifts (squat or leg press, deadlift or RDL, bench press or push-ups, rows, overhead press, pull-ups/lat pulldowns). Aim for 8–15 hard sets per muscle group per week, split across sessions.

Use progressive overload: Keep most sets in the 6–12 rep range and stop 1–3 reps shy of failure. Add a rep or small amount of weight when you hit the top of your rep range with good form.

Add cardio strategically: Do 2–3 sessions of 20–30 minutes (incline walking, cycling, or easy intervals). Keep it “supportive,” not exhausting—strength training should remain the priority for muscle gain.

Example 4-day split (repeatable and balanced)

Day 1 – Upper: Bench, row, overhead press, pulldown, curls, triceps.

Day 2 – Lower: Squat/leg press, RDL, lunges, hamstring curl, calves, core.

Day 3 – Upper: Incline press, pull-ups/pulldown, dumbbell row, lateral raises, arms.

Day 4 – Lower: Deadlift variation, split squat, hip thrust, leg curl, core.

Nutrition and recovery rules that make the routine work

Protein: Roughly 0.7–1.0g per pound of goal body weight daily. Calories: Keep a small deficit (about 200–400 calories) to lose fat without crushing training performance. Sleep: 7–9 hours nightly. Steps: 7,000–10,000 per day for steady fat loss without excessive fatigue.

FAQ

How long does it take to see muscle gain and fat loss at the same time?

Most people notice measurable changes in 4–8 weeks if training is progressive and protein is high. Visible body composition changes commonly take 8–12+ weeks, depending on starting point, sleep, and consistency.
