Bulking, a training method favored by many gym enthusiasts for swiftly achieving a universally admired physique, remains relatively new to some. So, what exactly is bulking, and why is it necessary? Explore more in this Mytour Blog article!
What is Bulking?
Bulking is a term in bodybuilding used to denote the muscle-building phase. During this period, individuals follow a high-intensity diet and exercise routine to create optimal conditions for muscle growth and size increase.
Bulking phases typically last between 4-8 weeks. Following the bulking phase, fitness enthusiasts transition to the cutting phase to shed excess fat while preserving the hard-earned muscle.

Why is bulking necessary?
Fat is an essential component of the body, providing protection to internal organs, regulating temperature, and serving as an energy source when needed. However, an excess of fat can lead to health issues. Hence, bulking is a crucial method to increase muscle mass and reduce excess fat. It's important to execute bulking properly to avoid adverse effects. Here are specific reasons why bulking is necessary:
- For Muscle Size: Bulking is the only effective way to increase muscle size. When you consume enough calories and train with high intensity, your body will have the energy and resources to build new muscle.
- Enhancing Strength: Larger muscles will help you lift heavier weights and train more effectively.
- Improving Physique: Bulking helps you gain weight and look healthier, more robust, and firmer.

How many types of bulking are there?
Bulking is a phase of nutrition and training aimed at gaining weight, primarily through muscle growth. There are two popular bulking methods: Clean Bulk and Dirty Bulk. Each method has different characteristics and implementation approaches.
Clean Bulk
Clean bulk is a healthy weight-gaining approach, focusing on increasing muscle mass while minimizing the accumulation of excess fat. In this method, individuals consume more calories than their daily expenditure, ensuring intake of foods rich in protein, complex carbohydrates, and healthy fats.
Advantages of Clean Bulk
- Enhances muscle growth efficiently: When the body has enough calories for physical activities, it prioritizes using calories to build muscles rather than storing excess fat.
- Minimizes the accumulation of excess fat: Consuming foods rich in protein, complex carbohydrates, and healthy fats helps the body absorb nutrients optimally, thereby minimizing the risk of excess fat accumulation.
- Improves overall health: Healthy weight gain contributes to a healthier body, reducing the risk of chronic diseases such as heart disease, diabetes, and more.
- Maintains reasonable weight:
Drawbacks of Clean Bulk
- May take longer to achieve desired results: Clean bulk is a healthy weight-gaining method, requiring individuals to be patient and committed.
- Requires knowledge of nutrition and exercise: To effectively implement clean bulk, individuals need knowledge of nutrition and exercise to build a plan suitable for themselves.

Dirty Bulk
Dirty bulk is a method to rapidly increase body mass, focusing on consuming high-calorie foods without considering their nutritional value. You might even indulge in foods like french fries, hamburgers...
Advantages of Dirty Bulk
- Aids rapid weight gain: Dirty bulk is the fastest method for quick weight gain, suitable for those aiming to gain weight rapidly for bodybuilding competitions.
- Reduces workout time: This approach helps individuals gain weight quickly, allowing them to spend less time on workouts compared to those following clean bulk.
- Enhances strength: Rapid strength enhancement enables individuals to lift heavier weights.
Drawbacks of Dirty Bulk
- Prone to excess fat accumulation: Dirty bulk disregards food quality, making individuals prone to excess fat accumulation.
- Reduces muscle-building effectiveness: Excess fat can hinder the muscle-building process.
- Impacts health: Accumulating too much excess fat can lead to health issues such as heart problems, diabetes, and more.

How long should bulking last?
The duration of bulking depends on various factors, including:
- Individual's goal: If the goal is rapid muscle gain, one can engage in a shorter bulking period. Conversely, for those seeking safe and sustainable muscle growth, a longer bulking duration may be suitable.
- Physical condition: Individuals with a lean physique may have a shorter bulking period compared to those who are overweight.
- Training capability: Consistent and effective training can lead to a shorter bulking period.
The common bulking duration ranges from 4 to 6 months. However, this timeframe may vary based on individual factors.

Nutritional guidelines for effective bulking
To effectively bulk, individuals need to establish a scientifically sound nutritional plan, ensuring an adequate supply of calories and essential nutrients for the body. The bulking diet should meet the following requirements:
- Consume more calories than daily expenditure: Excess calories will be utilized by the body to build muscle.
- Consume approximately 1.6-2.2 grams of protein per kg of body weight: Protein is the most crucial nutrient for the muscle-building process.
- Consume about 2-3 grams of complex carbohydrates per kg of body weight: Complex carbohydrates are the primary energy source for the body.
- Consume around 0.8-1 gram of healthy fats per kg of body weight: Healthy fats help the body absorb other nutrients more efficiently.

Some tips for bulking without gaining excess fat
Clean Bulk is a more effective and safer bulking method than Dirty Bulk. Individuals should opt for Clean Bulk to ensure efficient muscle gain without compromising health.
Set Clear Goals
Bulking is currently the most popular muscle-building method. However, not everyone knows how to apply bulking safely and effectively. In the initial stage, muscle development occurs rapidly as your body adapts to new workout intensity and diet. However, as time progresses, the rate of muscle growth slows down.
To ensure safety and effectiveness, aim to gain only about 0.5 – 1kg per week. Rapid weight gain may lead to excess fat accumulation. Additionally, avoid using steroids for muscle growth support, as they can have dangerous side effects on health.
Include Cardio in Your Workout
Many believe cardio is unnecessary during this phase. However, incorporating cardio into your routine provides numerous benefits for the bulking process:
- Promotes a healthy cardiovascular system: Cardio enhances blood flow, improving heart and lung function, crucial for high-intensity workouts.
- Aids in burning excess fat: Cardio burns calories, helping reduce excess body fat and enhancing muscle definition.
- Enhances nutrient circulation: Increased blood flow efficiently transports nutrients to muscles.
Instead of eliminating cardio altogether, integrate it with bulking. Aim for 2-3 cardio sessions per week, each lasting around 30-45 minutes.
Optimal Rest Time
Engaging in sports is one of the best ways to enhance health and fitness. However, for optimal results, you need a well-planned rest schedule. Resting allows the body time to recover, replenish energy, and develop muscles.
Eating Post-Workout
The golden window for post-workout nutrition is within 30 minutes after finishing your session. At this time, the body requires energy and protein to recover from damage and build new muscles. Ensure an adequate intake of carbs and protein after exercising. Carbs provide energy, while protein aids in muscle building and repair.
