Concentration Curls vs Preacher Curls

5 Shares

When it comes to building bigger and stronger biceps, there are numerous exercises to choose from.

However, two classics that often spark debate are concentration curls and preacher curls.

In this article, we will explore both of these exercises and help you determine which one is better for achieving your bicep goals.

Concentration Curls

Techniques and Equipment Needed

To perform concentration curls correctly, you’ll need a dumbbell and a place to sit. Begin by sitting down with your feet firmly planted on the ground and spread wider than shoulder-width apart.

Hold the dumbbell in one hand, with your palm facing up. Position your upper arm against the inside of your corresponding thigh.

It’s essential to use the proper technique to ensure you’re working the targeted muscles and reducing the risk of injury.

Now, curl the weight up to your shoulder level by flexing your bicep. Make sure to isolate the bicep muscle and avoid using momentum from other body parts.

Squeeze your bicep when you reach the top of the movement, then lower the weight in a slow and controlled motion.

Repeat this process for the desired number of reps and switch sides, ensuring equal work for both arms.

Benefits and Drawbacks

Concentration curls offer several benefits, including:

Isolation: This exercise effectively isolates the bicep and minimizes momentum, allowing for better muscle engagement.
Targeting the short head: Concentration curls target the short head of the bicep more effectively than other biceps exercises, like the standard barbell curl.
Prevention of muscle imbalances: By working one arm at a time, you can address any muscular imbalances between your left and right bicep.
Minimal equipment: You can perform concentration curls with just a simple dumbbell, making it an accessible exercise option.

However, there are also some drawbacks to be aware of:

Limited weight: Concentration curls typically involve less weight than compound biceps exercises, which might limit overall strength development to some extent.
Discomfort: Some people may experience discomfort in their elbow or shoulder joints while performing concentration curls.
Less stimulation of the long head: This exercise may not activate the long head of the bicep as much as other exercises, such as the barbell curl.

Despite these drawbacks, concentration curls are a valuable addition to your biceps routine.

Especially if you’re looking for an exercise that effectively targets the short head of the bicep and helps prevent imbalances.

Preacher Curls

Techniques and Equipment Needed

When you’re ready to perform preacher curls, make sure you have the following equipment available:

A preacher bench with a padded armrest
A barbell or EZ curl bar

Now, follow these steps to ensure proper technique:

Position yourself: Sit down on the preacher bench and adjust it to a comfortable height so your armpits are close to the top of the padded armrest.
Grip the bar: Hold the barbell or EZ curl bar in both hands, palms facing up, and make sure your grip is shoulder-width apart.
Set up: Rest your upper arms on the pad and extend your elbows fully.
Curl up: Flex your biceps and curl the bar up towards your chin.
Squeeze: At the top, pause and squeeze your biceps for maximum muscle activation.
Lower: Slowly lower the bar back down to the starting position while maintaining tension in your biceps.
Repeat: Perform the desired number of repetitions.

Benefits and Drawbacks

As with any biceps exercise, preacher curls have their share of benefits and drawbacks. Let’s take a quick look at some of them.

Benefits:

Heavier weights: Preacher curls allow you to lift more weight than concentration curls, aiding in your strength and muscle development.
Progressive overload: The ability to add weight incrementally makes it simpler to advance your lifts and increase bicep strength over time.
Equal targeting: This exercise targets both heads of the bicep muscle equally, providing balanced development.
Stability & support: The preacher bench provides stability and support for your elbows, which may help reduce the risk of injury.

Drawbacks:

Equipment: Preacher curls require a specific piece of equipment (the preacher bench), which may not always be available to you.
Range of motion: This exercise may reduce the range of motion of the curl compared to other bicep exercises, such as standing curls or concentration curls.
Isolation: While preacher curls do isolate the biceps, they may not provide as much isolation as concentration curls.

Preacher curls are certainly an effective biceps exercise that offers several benefits.

However, always consider the potential drawbacks and your individual preferences when incorporating them into your workout routine.

Concentration Curls vs Preacher Curls

When deciding between concentration curls and preacher curls, you’re essentially choosing between two effective exercises that target your biceps in slightly different ways.

It’s time to dive into the details and compare these two popular exercises to help you understand which might be better suited for your fitness goals.

Developing Strength and Size

When it comes to increasing strength and size, preacher curls may have an advantage since they allow for more weight and overload.

On the other hand, concentration curls might limit your potential for muscle growth due to lower resistance and volume.

Hypertrophy

Both types of curls can induce hypertrophy by creating muscle tension and damage.

However, concentration curls may slightly excel in stimulating the short head of the bicep, contributing to the bicep peak.

Whereas, preacher curls might have a slight edge in stimulating the brachialis, which pushes the bicep up and makes it look bigger.

Difficulty Level

Generally, the level of difficulty is similar for both concentration curls and preacher curls when performed with correct technique.

Concentration curls can be more challenging for beginners since they require additional balance and coordination.

Advanced lifters might find preacher curls more challenging, given that they reduce the use of momentum and “cheating”.

Muscle Activation and Mechanics

Both curls work to activate the biceps brachii, the brachialis, and the brachioradialis.

According to a study by the American Council on Exercise, concentration curls may activate the biceps more than preacher curls.

However, another study from the Journal of Strength and Conditioning Research suggests that preacher curls may activate the brachialis and brachioradialis more than concentration curls.

Variability

The variability in these exercises lies in the modifications made to grip, angle, or equipment.

Concentration curls can be performed with dumbbells, kettlebells, cables, or bands. It is primarily a single-joint exercise with limited variations

Preacher curls, on the other hand, can be done using barbells, EZ bars, dumbbells, or cables. They offer greater variability, including the use of different angles and equipment.

Ease of Access

Both types of curls can be performed at home or in the gym. Concentration curls have greater accessibility, only requiring a dumbbell and a bench or a chair.

In contrast, preacher curls need a preacher bench or an adjustable bench, making them slightly less accessible.

Which One Should You Do First?

Deciding whether to start with concentration curls or preacher curls can be a bit like choosing which sneaker to put on first.

Ultimately, it depends on your workout goals. If your aim is to truly isolate the biceps and focus on form without any help from other muscles, kick off with concentration curls.

They require a strict technique that ensures you’re targeting the bicep muscle directly, making them an excellent choice for beginners looking to build strength and proper movement patterns.

Switching over to preacher curls might be your next move if adding size is at the top of your list.

Preacher curls allow for heavier weights and more stability through the arms’ positioning, which can lead to greater muscle growth over time.

Just make sure you nail down that form first with concentration curls so when you increase the load, every rep counts towards sculpting those arm muscles effectively.

Remember not to rush; quality trumps speed when it comes to building impressive biceps!

Should You Do Both Exercises?

Doing both exercises can be beneficial for maximizing bicep development and avoiding plateaus.

You might be wondering if you should incorporate both concentration curls and preacher curls into your workout.

Here are some reasons and examples that explain why doing so would be advantageous for you:

Increasing total volume and intensity

Combining both exercises can enhance the overall volume and intensity of your bicep workout, leading to more growth and adaptation. This means that you’ll be able to achieve stronger biceps within a shorter time frame.

Targeting different aspects and functions of the bicep

Each exercise targets a different part of your bicep muscles. Concentration Curls primarily engage the short head of the biceps brachii, while Preacher Curls target the long head.

Doing both exercises ensures that you’re improving the shape and performance of your biceps comprehensively.

Preventing boredom and monotony

Let’s face it; repeating the same exercises every workout can become dull and decrease motivation. Alternating between Concentration Curls and Preacher Curls adds variety to your regimen, which in turn, enhances your enjoyment and motivation during workouts.

Creating versatile workout programs

You can modify your bicep workouts by incorporating both exercises in various ways, such as alternating sets, supersets, drop sets, or circuits. This additional challenge can add variety and excitement to your training sessions.

By incorporating both Concentration Curls and Preacher Curls into your routine, you’ll not only see improved results in your bicep development but also keep your workouts enjoyable and versatile.

Now, go ahead and give your biceps some love with both of these effective exercises!
