Bulking and Cutting: How to Build Muscle, Burn Fat, and Maximize Your Results
You’ve been putting in the work. Long sessions, heavy lifts, consistent effort—and the results are starting to show. But taking your physique to the next level can feel like cracking a complicated formula. That’s where smart strategy comes in. The good news? You don’t have to figure it all out alone.
Let’s break down the fundamentals of bulking and cutting—the proven approach athletes and bodybuilders use to add muscle, shed fat, and fine-tune their physique for maximum impact.
The Basics: What Is Bulking and Cutting?
Bulking is the intentional process of eating more calories than your body burns, with the goal of gaining size—specifically lean muscle mass.
Cutting (often called shredding) is the opposite: eating fewer calories than you burn to reduce body fat while preserving as much muscle as possible.
Most people cycle between these two phases—building muscle first, then trimming excess fat to reveal a stronger, more defined physique.
While the concept sounds simple, executing it correctly requires thoughtful planning, structured training, and intentional nutrition. According to Certified Nutrition Coach and Personal Trainer Kayla DeMarco, success comes down to clarity and consistency.
“Start by asking yourself, ‘What are my goals?’” says DeMarco. “Having a clear plan before you take action makes all the difference.”
That plan should guide both how you train and how you fuel your body.
Train With Purpose: Adjust Your Workouts to Match Your Goals
Your gym routine should align with whether you’re bulking or cutting.
-
Bulking workouts prioritize heavy weight training, lower reps, and minimal cardio. The focus is progressive overload—lifting heavier over time to stimulate muscle growth.
-
Cutting workouts shift toward lighter weights, higher reps, and increased cardio to boost calorie burn while maintaining muscle.
To keep it simple:
Bulking = heavier weight + fewer reps
Cutting = lighter weight + more reps
When it comes to cardio during a cut, DeMarco recommends high-intensity formats like HIIT (High-Intensity Interval Training) and EMOM (Every Minute on the Minute) workouts for efficiency and fat loss.
Nutrition Is the Game Changer
Training sets the foundation, but nutrition determines how well your body responds to that work.
The Bulk
A successful bulk requires a calorie surplus, supported by all three macronutrients: protein, carbohydrates, and fats. Carbs play a major role here, as they fuel intense training sessions and support recovery.
“To be most accurate during your bulk, tracking your macros is essential,” says DeMarco.
Hitting higher calorie and macro targets consistently helps ensure that the weight you gain supports muscle growth—not just unnecessary fat.
The Cut
Cutting demands discipline. You’ll need to maintain a calorie deficit, meaning you’re burning more energy than you consume. However, protein intake becomes even more important during this phase.
“When you’re eating less, keeping protein high helps you stay full and protects lean muscle mass,” DeMarco explains. “It allows your body to target fat stores while holding on to muscle.”
Balancing your macros properly during a cut is key to achieving that lean, defined look without sacrificing strength.
Stay Focused on Your Journey
Your fitness journey is personal. What works for someone else may not work the same way for you—and that’s okay.
“It’s important not to get caught up in what others are doing,” DeMarco emphasizes. “Every body responds differently. Stay consistent, focus on your own goals, and the results will come.”
With a clear plan, smart training, and dialed-in nutrition, bulking and cutting can become powerful tools—not confusing obstacles—on your path to building your best physique yet.
