Do Barbell Curls Work Forearms?


Brachioradialis and Brachialis muscles are responsible for your forearm movement, which means they engage the forearms muscle group when you curl weights.

They also help with supporting the biceps during a curl, since this is an elbow-flexion motion. By strengthening these muscles, you can help increase overall arm strength and size.

Do Barbell Curls Work Forearms?

Brachioradialis and brachialis muscles are responsible for the movement of your forearm, which helps you perform tasks like gripping objects and raising your arm overhead.

They also help support the muscle in your biceps during a curl, helping to make it stronger. The Brachioradialis is larger than the Brachialis, so engaging both muscles will produce a more robust contraction.

Strengthening these muscles can improve overall shoulder mobility and range of motion.

Brachioradialis and Brachialis Muscles

Yes, barbell curls work your brachioradialis and brachialis muscles. When you curl the weight, you’re using your biceps and triceps to help move the weight.

The Brachioradialis muscle is located on the side of your upper arm just below your shoulder blade, while the Brachialis muscle is located on top of your forearm near the hand.

Curling with a heavier weight will target more strength in these two muscles than curling with a lighter weight will. You’ll see bigger arms and shoulders if you incorporate regular barbell curls into your workout routine.

Engages Forearm Muscles

Yes, barbell curls work your forearms because they engage the forearm muscles. You can do them with weights or without weights and you can also use resistance bands to make them harder.

The more repetitions you do, the stronger your forearms will get. Make sure that you keep a good range of motion when doing the exercises so that they don’t become painful and counterproductive in the long run.

Forearm workouts are an excellent way to tone and strengthen your arm muscles while getting some cardio benefits as well.

Supports Biceps During Curl

Yes, barbell curls work forearms because they help to support the biceps during the curl. By using a heavier weight and keeping your elbows close to your body, you can maximise the amount of resistance you create for your forearm muscles.

Holding the contraction for a longer period of time will also increase muscle growth in this area. You don’t need any special equipment to do barbell curls; just use a standard bench and weights that are comfortable for you to handle. Forearm workouts should be done at least three times per week if you want them to have maximum impact on muscle development.

Do curls workout your forearm?

Yes, curls can work your forearm. When you curl weights, the weight moves through a range of motion that includes your wrists and forearms. This action helps to build muscle and strength in these areas.

Bicep Curls

The biceps are a group of two muscles located on the front side of your upper arm. They consist of two heads, the larger one called the brachialis and the smaller one called the bicipitalus. When you curl something, you are contracting these muscles together.

Forearm Flexors

Your forearm flexors also known as supinator muscle are responsible for moving your hand away from your body when you bend it at the wrist – this is what allows you to do things like pick up an object with your thumb down by your palm or make a fist.

Muscles Associated With Arm flexion

When doing curls, some of these muscles include: Brachioradialis (the largest), Triceps brachii (infraspinatus and teres minor), Erector spinae (iliocostalis lumborum and erector spinae longissimus), Serratus anterior ( Browridge et al., 2009 ).


So while curls may not be THE answer to building stronger forearms they certainly won’t hurt anything. In fact, if done correctly they can actually workout some pretty important forearm muscles in addition to giving that toned look we all love.

Why do I feel barbell curls in my forearms?

If you feel barbell curls in your forearms, it could be a sign of muscle weakness or injury. This can happen when the muscles around those arms become too weak to support the weight of the barbell. If this is happening regularly and you don’t have any other symptoms, it may just be a temporary issue and will go away on its own. But if it’s causing pain or difficulty performing everyday tasks, there may be something more serious going on. So make sure to see a doctor to figure out what’s wrong.

No Warm Up

When you exercise without warming up, you are putting your muscles under tension and not giving them the chance to relax and lengthen. This can lead to pain and inflammation in the muscles.

Exercising Without Proper stretching

Stretching before every workout helps to avoid injuries as well as improve flexibility and range of motion. It also allows the body to absorb more oxygen which will help with energy production during your workout.

Not Enough Volume or Intensity

If you are working out at a low volume or intensity, you are not providing your muscles with enough stimulation for growth and strength gains. You may find that you plateau quickly if this is the case.

Tension In Muscles

Do forearms grow with bicep curls?

There is some debate over whether or not forearms grow with bicep curls. Some people believe that they do, while others think the opposite is true. The truth likely lies somewhere in between, as both exercises will cause muscles to grow and become stronger.

  • The muscles in your forearms are responsible for a number of different movements, including curls and wrist exercises. When you do these exercises regularly, the arm muscles will grow larger over time. This is because they are working more often and with greater intensity than before.
  • Curls work the entire length of your forearm and can be done using any type of weight or resistance equipment. They also provide an excellent exercise to improve grip strength and flexibility in the wrists.
  • Forearm curls should be performed with a moderate amount of weight to avoid excessive strain on the elbow joint, which could lead to injury down the road.
  • Wrist extension exercises help increase range-of-motion in both hands as well as strengthen tendons, ligaments and muscle groups along the back of your hand and fingers.

Which muscles do barbell curls work?

When you do barbell curls, the muscles in your back, shoulders and arms are working hard. These include the pectorals (pecs), deltoids (thighs), triceps and hamstrings.

  • The biceps Brachii is the large muscle located on the front of your upper arm. It helps you to curl weights, and it’s responsible for the majority of the movement involved in a barbell curl.
  • The brachialis is a smaller muscle located just below the biceps Brachii. It also helps with curling weights, but its main purpose is to help flex your elbow joint.
  • Finally, the muscles that make up your forearm – specifically, the brachialis and extensors (the long muscles) – are activated during every repetition of a barbell curl exercise.

When I do barbell curls my forearms hurt?

If you’re experiencing pain when doing barbell curls or any other type of arm workout, it may be because of tendonitis. Overuse from lifting weights that are too heavy can also cause tendonitis, as can repetitive motion or a motion that is too hard.

Treatment for tendonitis usually involves rest and ice therapy to reduce inflammation and swelling. A doctor will often prescribe antibiotics if the infection is severe, but most cases resolve on their own with proper treatment over time.

Should you feel bicep curls in forearm?

You should feel the bicep curls in your forearm if you’re activating it. It’s not a bad thing to have strong forearms, as long as you’re benefiting from them.

Exercising your forearms will help improve their strength and tone. Be sure to use weights that are appropriate for your level of fitness and experience so you don’t injure yourself unnecessarily.

To Recap

There is no one-size-fits-all answer to this question, as the amount of strength and size you can achieve with barbell curls will depend on your individual physique.

However, if you are looking for a workout that targets both your forearms and biceps muscles simultaneously, then barbell curls may be a good option for you.
