Why Do Bodybuilders Cut and Bulk - Why Do Bodybuilders Cut and Bulk?

The practice of “cutting” and “bulking” is common among professional bodybuilders. But why do they do it?

This blog post will explore the history and science behind this controversial training method.

Bodybuilders have been using the cut-and-bulk method for years to achieve the ripped, muscular physiques they are known for.

But what exactly is this method? And more importantly, does it work?

What are the cut and bulk? – Overview

In short, a cut-and-bulk method is a two-phase approach to bodybuilding in which athletes first gain muscle mass (known as “bulking”) and then lose fat (known as “cutting”).

This cycle is usually repeated several times throughout the year to allow the bodybuilder to achieve peak competition conditions.

The cut-and-bulk method is a controversial training method, with some experts claiming that it's an effective way to build muscle and others asserting that it's nothing more than a bodybuilding fad.

So, what's the truth? Let's take a look at the history and science behind the cut-and-bulk method to find out.

The History of Cutting and Bulking

The idea of cutting and bulking actually has its origins in boxing. Back in the day, boxers would gain a lot of weight leading up to a fight.

They would “bulk up” to be heavier than their opponent and have an advantage in the ring.

The problem was that all that extra weight made them slow and sluggish.

So, they would “cut” right before the fight to drop the excess weight and be faster on their feet.

Bodybuilders borrowed this idea and adapted it for their purposes.

They realized that if they could add more muscle mass during the off-season, they would be bigger and stronger when they started cutting for competition.

And being bigger and stronger would give them an advantage over the competition.

The Science of Cutting and Bulking

Cutting and bulking cycles are based on two simple principles: hormones and calories.

When you're trying to bulk up, you need to consume more calories than you burn so your body has extra energy to build muscle.

When you're trying to cut, you need to consume fewer calories than you burn so your body will start burning stored body fat for energy.

It's also important to note that testosterone levels play a role in muscle growth.

Testosterone is a hormone that helps build muscle mass. So, when bodybuilders are trying to bulk up, they often take testosterone supplements to help them increase their muscle mass.

And when they're trying to cut, they may use drugs like human growth hormone (HGH) or insulin-like growth factor 1 (IGF-1) to help preserve their muscle mass while they're losing body fat.

Why Do Bodybuilders Cut and Bulk?

If you've ever seen a bodybuilder on stage, you know that they look absolutely massive.

Their muscles are so big that they seem to burst out of their skin.

But how do they get so big?

And how do they maintain that size all year round?

The answer is simple: they go through cycles of cutting and bulking. Cutting is the process of shedding body fat while bulking is the process of building muscle mass.

By alternating between these two phases, bodybuilders can achieve their impressive physiques.

So why do bodybuilders cut and bulk?

There are a few reasons. First, it allows them to manage their weight effectively. A bodybuilder trying to bulk up will need to eat a lot of calories to gain weight.

However, this can also lead to an increase in body fat. By alternating between cutting and bulking, bodybuilders can avoid this problem.

Second, it helps them to maintain their muscle mass. When a bodybuilder is in a cutting phase and shedding body fat, they may also lose some muscle mass.

By alternately bulking and cutting, they can ensure that they keep their muscles while still losing body fat.

Finally, it allows them to stay shredded all year round. By going through cutting and bulking cycles, bodybuilders can maintain low body fat levels, even during the off-season. This gives them an aesthetic advantage when competing against other bodybuilders who have not followed this approach.

Cutting and bulking is essential for bodybuilders who want to build muscle and stay shredded all year round.

By alternating between these two phases, they can manage their weight effectively, maintain their muscle mass, and stay shredded all year round.

Here are a few tips:

  • Have a clear plan and goal in mind. What are you trying to achieve by cutting or bulking? Having a clear plan will help you stay focused and on track.
  • Monitor your progress closely. Keep track of your weight, body fat percentage, measurements, and feelings. This will help you see what's working and what isn't.
  • Make sure you're getting enough sleep. Sleep is essential for muscle growth and recovery.
  • Stay hydrated. Drinking plenty of water will help you stay healthy and avoid cramps or other problems.
  • Eat clean and healthy foods. Eating nutritious foods will help your body recover from workouts and build muscle effectively.
  • Supplement smartly. If you take supplements, ensure you're taking ones that will help you reach your goals.

The benefits and drawbacks of the cut and bulk method

The cut and bulk method is popular for muscle growth among bodybuilders and strength athletes.

The basic idea is to first “cut” or lose body fat by eating in a calorie deficit, then “bulk” or build muscle mass by eating in a calorie surplus.

This approach has benefits and drawbacks, which we will explore in more detail below.


1. You can lose fat and build muscle simultaneously: This is the main advantage of the cut and bulk method. By alternating between calorie restriction and calorie surplus phases, you can theoretically continue to lose fat while also building muscle.

2. It’s a flexible approach: Another advantage of the cut and bulk method is that it’s relatively flexible. You can tailor your calories and macros to suit your individual goals and preferences. For example, if you want to gain muscle mass quickly, you can eat more calories during your bulk phase. Or, if you’re trying to lose fat without sacrificing too much muscle, you can eat fewer calories during your cut phase.

3. It helps prevent weight fluctuations: This approach can also help prevent the weight fluctuations common when dieting. When you diet for extended periods, your weight often yo-yos up and down as your body adjusts to the new calorie intake. However, by alternating between phases of calorie restriction and surplus, you can minimize these fluctuations.


1. It takes longer to achieve results: The main downside of the cut and bulk method is that it takes longer to achieve results than other approaches. If your goal is to lose fat quickly, you might be better off doing a dedicated cutting phase followed by a maintenance phase.

2. It requires more discipline: This approach requires more discipline than other methods, as you must be very strict with your diet during cutting and bulking. If you struggle with dietary self-control, this might not be your best approach.

3. You have to be careful not to overdo it: Finally, it’s important to be careful not to overdo it with this approach. You won't achieve the desired results if you eat too many calories during your bulk phase or too few calories during your cut phase.

While the cut and bulk method have advantages, it’s not necessarily the best approach for everyone. It’s important to consider your individual goals and preferences before deciding which method is right for you.

Final Thought

The cut-and-bulk approach is a controversial training method that has been used by professional bodybuilders for decades.

While some experts claim that it's an effective way to build muscle, others assert it's nothing more than a bodybuilding fad.

The truth lies somewhere in between; when done correctly, the cut-and-bulk method can be an effective way to build muscle mass and lose fat.

However, it's important to remember that this approach requires careful planning and execution to succeed.
