Are you stuck spinning your wheels in the gym—training hard but barely seeing gains? Then it’s time to ditch the myths and learn how to run a proper lean bulk backed by science. In this article, I’ll walk you through the exact strategy I used to build more muscle this year than I have in the last five—and how you can do it too.
💡 What Is Bulking and Why Should You Do It?
Bulking simply means eating in a caloric surplus—consuming more calories than your body burns—to create the ideal environment for muscle growth.
While main gaining (maintaining your weight while gaining muscle) is possible, it’s not optimal. Here’s why:
- Your body prioritizes survival, not muscle.
- Without a surplus, you won’t have the raw materials needed to build tissue.
- Research shows greater muscle gain when eating in a moderate surplus, especially in trained individuals.
⚖️ How Much Weight Should You Gain on a Bulk?
To maximize muscle and minimize fat, follow these monthly weight gain targets:
- Beginners: 1–2% of body weight per month
- Intermediates: 0.5–1% of body weight per month
- Advanced: 0.25–0.5% per month
✅ Example: If you weigh 170 lbs and are an intermediate lifter, aim to gain 0.85–1.7 lbs per month.
Avoid dirty bulking. Gaining weight too quickly = fat gain.
🍽️ Setting Your Calorie Target for Lean Bulking
- Estimate your maintenance calories:
- Multiply your bodyweight in lbs by 14–16.
- Example: 180 lbs × 16 = ~2,880 calories/day
- Add 5–10% for a surplus:
- 2,880 + 10% = ~3,150 calories/day
- Track your progress:
- Adjust every 2–3 weeks based on weight change.
💡 Pro tip: Use an app like MacroFactor to automate calorie adjustments as your metabolism adapts.
🥗 What Should You Eat While Bulking?
🔹 Protein
- 0.7–1 gram/lb of bodyweight
- Ex: 170–180g protein/day for a 180 lb individual
🔹 Fat
- 20–30% of total calories
- Ex: On a 3,000-calorie bulk, aim for 65–100g of fat
🔹 Carbs
- Fill in remaining calories after hitting your protein and fat targets
- Carbs fuel performance and recovery—don’t skimp on them!
🍳 Sample Lean Bulk Meal Plan (3,000 Calories)
| Time | Meal | Notes |
|---|---|---|
| 10:00 AM | Eggs, oats, blueberries, cheese, veggies | High-protein + slow carbs |
| 1:00 PM | Ground turkey, jasmine rice, Greek yogurt | Pre-workout meal |
| 4:00 PM | Protein shake + banana (post-workout) | Fast-digesting recovery |
| 7:00 PM | Chicken, potato, broccoli, sunflower seeds | Flexible dinner |
| 10:00 PM | Greek yogurt, honey, peanut butter, popcorn | Casein protein + fats |
🎯 Want flexibility? Track macros instead of rigid meal plans. You can still fit in a treat or two.
🏋️♂️ What About Training During a Bulk?
This is where many people fail: they eat more but don’t train hard enough.
🔹 Beginners
- 3–4 days/week
- Focus on compound movements, progressive overload
🔹 Intermediates
- 4–5 days/week
- Aim for 8–15 sets per muscle per week
- Add volume gradually
🔹 Advanced
- Consider specialization blocks
- Use advanced techniques like myo-reps, lengthened partials, and volume cycling
Rule #1: If you’re not training hard, your bulk becomes a fat-gain phase.
❤️ Should You Do Cardio During a Bulk?
Yes. Here’s why:
- Improves work capacity (you’ll train harder, longer)
- Supports cardiovascular health
- Reduces fat gain indirectly by increasing energy expenditure
💡 2–3 sessions of moderate cardio (e.g., brisk walks, light basketball) per week is plenty—unless you work a physically demanding job.
💊 Recommended Supplements for Bulking
| Supplement | Purpose |
|---|---|
| Creatine (5g/day) | Strength & muscle mass |
| Whey protein | Convenience (fill gaps in diet) |
| Fish oil (2g EPA/DHA) | Heart, brain, and joint health |
| Vitamin D | Hormonal health (especially in winter) |
| Magnesium | Sleep, recovery, testosterone |
Optional: Caffeine pre-workout, Ashwagandha (with caution)

🚀 Final Thoughts: Why You Should Commit to a Bulk
If you’ve never run a real bulk, you’re likely leaving gains on the table. A well-structured lean bulk:
- Maximizes muscle growth
- Minimizes fat gain
- Builds long-term progress
It’s not outdated. It’s not “Bro Science.” It’s backed by biology and research—and it works.
