Understanding Muscle Growth
Before we tackle the hardest muscle to grow, it’s important to understand the process of muscle growth, also known as hypertrophy. Muscle hypertrophy occurs when muscle fibers increase in size due to resistance training or other forms of exercise. Two primary factors contribute to muscle growth: mechanical tension and metabolic stress.
Mechanical tension refers to the force exerted on a muscle during resistance training. When a muscle is subjected to mechanical tension, it experiences micro-tears in its fibers. The body responds to these micro-tears by repairing and rebuilding the muscle fibers, making them thicker and stronger. This process is known as muscle protein synthesis.
To maximize muscle growth, it’s essential to apply progressive overload, which means gradually increasing the amount of tension on your muscles over time. For more information on how to progressive overload properly, check out our guide on progressive overload.
Metabolic stress is another key factor in muscle growth. It occurs when a muscle is subjected to high-intensity exercise, resulting in the accumulation of metabolic byproducts, such as lactate and hydrogen ions. This buildup creates a burning sensation in the muscle, indicating that it’s working hard. Metabolic stress is thought to stimulate muscle growth by increasing the release of anabolic hormones, promoting cell swelling, and enhancing muscle protein synthesis.
Now that we have a basic understanding of muscle growth, it’s important to recognize that not all muscles grow at the same rate. Factors such as muscle fiber type, genetics, and training techniques can all influence how quickly a muscle grows. In the next sections, we’ll identify the hardest muscles to grow and discuss the unique challenges associated with each.
By understanding the science of muscle growth and the factors that make certain muscles harder to grow, you’ll be better prepared to tailor your workout routine and nutrition plan to overcome these challenges.

Hardest Muscle To Grow: The Calves
One of the most notoriously difficult muscles to grow are the calves. Located on the back of the lower leg, the calf muscles consist of two primary muscles: the gastrocnemius and the soleus. These muscles play a crucial role in walking, running, and jumping, making them essential for overall lower body strength and stability.
Anatomy and Function
The gastrocnemius is the larger, more superficial muscle responsible for the classic “calf” shape, while the soleus lies beneath the gastrocnemius and contributes to overall calf thickness. Both muscles work together to plantarflex the ankle joint, allowing you to push off the ground during movement.
Why Calves Are Hard to Grow
There are several reasons why the calves are considered the hardest muscle to grow:
- Genetics: Some individuals are naturally predisposed to have smaller calves due to their genetic makeup. Factors such as muscle fiber composition and insertion points can influence the size and shape of your calves.
- High Muscle Endurance: The calves are primarily composed of slow-twitch muscle fibers, which are more resistant to fatigue and less responsive to growth compared to fast-twitch fibers. As a result, they require more targeted and intense training to stimulate growth.
- Neglect: Many people overlook calf training in their workout routine or fail to train them with the same intensity as other muscle groups. This lack of attention can hinder calf development.
Tips for Growing Calves
Despite these challenges, it is possible to grow your calves with a dedicated and strategic approach. Here are some tips to help you target your calf muscles:
- Frequency: Train your calves at least 2-3 times per week, incorporating both heavy and high-rep training to target different muscle fibers.
- Variety: Include a mix of exercises, such as seated and standing calf raises, to engage both the gastrocnemius and soleus muscles.
- Full Range of Motion: Perform each calf exercise with a complete range of motion, stretching the muscle at the bottom and fully contracting at the top.
- Tempo: Experiment with slower tempos to increase time under tension and stimulate growth.
With persistence and the right approach, you can conquer the challenge of growing your calves. For more training tips, refer to our Ultimate Guide to Strength Training.
The Challenge of Growing The Rear Deltoids
Another muscle group that’s often difficult to grow is the rear deltoids or rear delts. The rear deltoids are one of the three heads of the deltoid muscle, located on the back of the shoulder. They play a critical role in shoulder stability, posture, and upper body aesthetics.
Anatomy and Function
The rear deltoids are responsible for several shoulder movements, including shoulder extension, horizontal abduction, and external rotation. They work together with the other deltoid heads (anterior and lateral) and various upper back muscles to provide strength and stability to the shoulder joint.
Why Rear Delts Are Hard to Grow
There are a few reasons why the rear deltoids can be challenging to grow:
- Underdevelopment: Many people focus on training the more visible anterior and lateral deltoids, neglecting the rear delts. This can lead to an imbalance in shoulder development.
- Poor Mind-Muscle Connection: The rear delts are a relatively small muscle group that can be hard to activate, especially if larger muscles, like the traps and lats, tend to dominate during exercises.
- Limited Exercise Selection: There are fewer exercises that specifically target the rear delts compared to other muscle groups, making it essential to choose effective movements.
Tips for Growing Rear Delts
To successfully grow your rear deltoids, consider the following tips:
- Isolation Exercises: Include isolation exercises, such as rear delt flyes, face pulls, and reverse cable crossovers, to specifically target the rear delts without interference from larger muscle groups.
- Compound Movements: Incorporate compound exercises like rows and pull-ups to engage the rear delts in a more functional way. Make sure to use proper form and focus on activating the rear delts during these movements.
- Mind-Muscle Connection: Improve your mind-muscle connection by using lighter weights and concentrating on the contraction of the rear delts during each rep.
- Frequency: Train your rear delts 2-3 times per week to stimulate growth.
By incorporating these tips into your workout routine, you can overcome the challenges of growing your rear deltoids. To further optimize your training, check out our article on Compound Vs Isolation Exercises.
Making The Forearms Bigger and Stronger
The forearms are another muscle group that can be challenging to grow. Comprising numerous smaller muscles responsible for wrist and finger movement, the forearms contribute to grip strength, overall arm aesthetics, and functional capabilities in daily life.
Anatomy and Function
The forearms consist of two main groups of muscles: the flexors and the extensors. The flexors are responsible for wrist and finger flexion, while the extensors control wrist and finger extension. These muscles work together to enable a wide range of motion and strength in the wrist and fingers.
Why Forearms Are Hard to Grow
Several factors make the forearms difficult to grow:
- High Muscle Endurance: Similar to the calves, the forearms contain a higher proportion of slow-twitch muscle fibers, which are more resistant to fatigue but less responsive to growth.
- Indirect Training: Many people rely on indirect forearm training through compound exercises like deadlifts and pull-ups. While these exercises do engage the forearms, they may not provide enough targeted stimulus for optimal growth.
- Neglect: Forearms are often overlooked in workout routines, leading to underdevelopment compared to other muscle groups.
Tips for Growing Forearms
To effectively grow your forearms, consider these strategies:
- Direct Forearm Training: Incorporate exercises that specifically target the forearm muscles, such as wrist curls, reverse curls, and farmer’s walks.
- Grip Strength: Improve grip strength by using tools like grip trainers, fat gripz, or even just hanging from a pull-up bar for time. For more tips on grip training, read our article on How To Train Grip Strength.
- Frequency: Train your forearms at least 2-3 times per week to provide ample stimulus for growth.
- Progressive Overload: Gradually increase the resistance, volume, or time under tension for your forearm exercises to promote continued growth.
By giving your forearms the attention they deserve, you can make them both bigger and stronger. For a comprehensive strength training plan, refer to our Ultimate Guide to Strength Training.
