How to Get Bigger Arms

If you desire bigger, more muscular arms, you’re not alone. Many people strive for this fitness goal, whether it’s for aesthetics or improved functional strength. Building bigger arms requires focusing on the correct exercises, muscle growth, and an effective strength training routine.

By targeting both your biceps and triceps, you can achieve balanced, significant muscle growth in your upper arms. Incorporating a combination of exercises that isolate and engage these muscles is the key to seeing noticeable results.

In addition to exercise, proper nutrition and recovery are critical to building bigger arms. In this article, we’ll discuss all the ways to enable you to reach your fitness goals more efficiently.

Understanding Your Arm Muscles

To build bigger arms, you need to understand the main muscle groups involved. 

Your arm muscles can be divided into three main groups: biceps, triceps, and forearms.

Understanding these key muscle groups can help you get the most out of your arm workouts. By targeting the right muscles, you can achieve more prominent, more sculpted arms.

Biceps Brachii

The biceps, or biceps brachii, located on the front side of your upper arm, is the most prominent and widely recognized muscle associated with strength and physical power. This muscle aids in bending your arm at the elbow and rotating your forearm to face your palm upwards.

It has two sections, or ‘heads,’ which begin at different sites on the shoulder and then join on the radius bone in your forearm. The bulk of the biceps muscle provides strength, while the long tendons help control movement.

Triceps Brachii

The triceps or triceps brachii are what make up your upper arm’s rear part. This powerful three-headed muscle is primarily responsible for extending the elbow, essentially straightening your arm.

Part of this muscle bundle facilitates the backward and downward movement of the arm. Keeping your triceps fit can help control flabbiness at the back of the arm.


Right underneath your biceps is the brachialis, a muscle that plays a crucial role in moving your arm. It’s the primary muscle responsible for bending your elbow.

It’s essential to your body’s mobility and strength, allowing you to lift heavy items and perform pushing movements.


The brachioradialis located on the outside of your forearm assists with flexing your elbow, helping your biceps and brachialis.

This muscle also provides stability to your elbow during rapid movements and allows the controlled rotation of the wrist.

Pronator Teres

The pronator teres is one of the key muscles allowing rotation of your forearm. It’s located on the inside of your elbow and enables your wrist to turn so your palm faces downwards.

Working this muscle can help improve your grip strength and your ability to perform activities that require a firm twist of the arm.

Lifestyle Changes for Bigger Arms

Whether you’re an aspiring bodybuilder or simply an individual desiring more defined and robust arms, there are several ways you can upgrade your current lifestyle to achieve this goal.

By integrating these changes, you can boost not only the size but also the strength and flexibility of your arms.

Starting with Strength Training

Incorporating weightlifting into your routine is vital to developing bigger arms. By focusing on exercises that target your biceps and triceps and progressively increasing the weights you lift, including the sets you complete, you gradually build up these muscles.

Muscles increase in size when they are continually exposed to deal with heavier weights and stronger resistance. 

Remember also to work out your shoulders and core to have a balanced physique and an overall strong body.

Growing Arms While Resting

Rest days are a crucial part of any training program. When the muscles are injured or damaged through resistance training, muscle fibers are fused as a part of the recovery. This muscle hypertrophy is what gives it more mass and increase in size.

Giving your muscles time to repair and grow after your workouts helps prevent injuries and ensures you’re ready for your next lifting session. Consider having at least one rest day between your arm muscle training sessions.

Switching to a High-Protein Diet

To support the growth of your muscles, make sure that you are getting an adequate amount of protein in your diet.

Consuming protein-rich foods like lean meats, eggs, dairy, and legumes post-workout will fuel your muscle growth and repair.

Staying Hydrated

Drinking plenty of water not only supports general health but also promotes muscle recovery after intense workouts.

Keeping hydrated throughout the day aids in the transportation of nutrients to your muscles, helping you to have more endurance, as well as stronger and healthier muscles over time.

Getting Adequate Sleep

Your hormones peak during deep sleep, making your downtime essential for muscle growth. Try aiming for 7-9 hours of sleep each night.

According to research, both duration and quality of sleep have an effect on muscle mass reduction and fat accumulation. Poor sleep can also hamper your energy levels and training performance, which could hinder your muscle growth.

Monitoring Your Progress

Consistently monitor your exercise routines and frequently take measurements of your arms to gauge your advancement. Adjust your training and nutrition accordingly to optimize your results.

Patience is crucial; significant gains take time. Stay focused, as your dedication will pay off.

Exercises to Get Bigger Arms

To effectively build bigger arms, it’s crucial to target both the biceps and triceps. Incorporate a variety of exercises into your routine, focusing on different rep ranges for optimal muscle growth. 

Make sure to use proper form and technique, and give your muscles sufficient rest between workout sessions. You may seek the assistance of a professional Personal Trainer to guide you with your training exercises.

Barbell Bicep Curls

One of the classic exercises for increasing bicep mass is the barbell curl. Assume a stance with your feet spread as wide as your shoulders, hold the barbell with your palms upwards, and ensure your elbows are snug to your body.

Lift the barbell by flexing your elbows, making sure to contract your biceps at the highest point of the movement before gradually dropping the weight.

Tricep Pushdowns

Tricep pushdowns help tone and strengthen the triceps. Stand before a high pulley with a rope or bar attachment. Grasp the attachment with your palms facing down.

Keep your elbows by your side while you use your triceps to push the attachment down towards your thighs and then allow it to return back up slowly.

Hammer Curls

Primarily, the brachialis and the brachioradialis muscles are targeted during hammer curls, leading to an increase in the overall fullness of the arm. Hold two dumbbells at your sides with palms facing towards your torso, then bend your elbows to lift the dumbbells.

Your palms should face each other throughout the exercise, mimicking the motion of using a hammer.

Skull Crushers

This aggressive-sounding exercise is excellent for targeting your triceps. While using an EZ bar or barbell loaded with a comfortable weight you can do multiple repetitions with, lie flat on your back on a bench. Hold the weights above your chest supported by your bent elbows.

Extend your arms to lift the weights, but keep your elbows in the same position, hence the idea of ‘crushing the skull’. Control is critical during this exercise to avoid injury.

Reverse Barbell Curls

The reverse curl is considered as an effective exercise for forearm development and involves holding your barbell with an overhand grip.

Keep your elbows tucked into your sides and slowly curl the barbell upwards, squeeze at the top, and then slowly lower it back down.

Medical Options for Bigger Arms

Besides the natural lifestyle changes and exercises to beef up your arms, there are also medical interventions available if those means are not giving you the results you desire.

For individuals seeking more immediate or substantial changes, various medical avenues can be explored, ranging from prescription supplements to surgical procedures.


Physiotherapy could help you with muscle development. A physiotherapist can develop tailored exercises to strengthen weak muscles, improve stamina, and increase muscle size over time.

This intervention is excellent for individuals recovering from an injury or those who need to strengthen a specific arm muscle due to medical conditions.

Fat Transfers

Fat transfer to arms, also known as fat grafting, is another surgical procedure that could be used to increase the size of your arms. This involves extracting fat from one part of your body through a process called liposuction and injecting it into your arms.

The advantage of this surgery over implants is that it uses your tissue, reducing the risk of an allergic reaction or rejection. However, like any other surgical procedure, it carries its risks and side effects, which your surgeon should fully explain to you before undertaking the procedure.

Hormone Supplements

Testosterone and Human Growth Hormone (HGH) are two hormones that could increase muscle size.

Doctors may prescribe these to patients who have a medically-diagnosed deficiency, which results in muscle weakness.

Therapeutic Steroids

Your doctor might prescribe anabolic steroids, synthesized drugs that mimic testosterone, to help improve your muscle mass and strength.

However, medical professionals usually only recommend these to treat specific medical conditions, and they’re accompanied by significant potential side effects.

Overuse or misuse of steroids can lead to health problems such as heart disease and liver damage.

Bicep Implants

Bicep implants are the more radical option when it comes to medical interventions for arm enlargement. This surgical procedure involves placing silicone implants into the upper arm to create the illusion of larger biceps.

It should be noted, however, that this procedure doesn’t enhance muscle strength or function. You should discuss this option thoroughly with a qualified plastic surgeon to understand its pros and cons, possible complications, and post-operative care.

Remember, any form of medical intervention requires guidance from a healthcare professional to ensure your safety. Always consider natural methods first before deciding on a medical intervention to get bigger arms.
