Barbell Curl vs Dumbbell Curl : How both hit differently and how maximum gains can be achieved through their rotation ?

  • Barbell curl is one of the ideal exercises to gain bigger biceps. 
  • Barbell curls target the muscle group responsible for arm flexion, the  biceps brachii and the brachialis.
  • Dumbbell curls target the brachioradialis muscle in your forearms that provide strength and grip.
  • Dumbbell curls are effective to improve the grip and allow you to perform isolation exercises like deadlift, pull-ups and bench presses efficiently.
  • Barbell curls are more efficient than the dumbbell curls, as also shown through research studies.
  • Barbell curls target/provide the bilateral movements, unlike the dumbbell curls that provide unilateral movements.
  • Unilateral movements take more energy and strength and target just one muscle group.
  • Bilateral movements take half of the energy and strength, meanwhile target two muscle groups at the same time.

If you are a gym enthusiast, you will always try to make the most out of your workouts.

Most people will do specific exercises that they believe to be the best.

If you have a complete workout plan, you will try to do a combination of various exercises.

Doing different exercises will help you develop multiple muscle groups for a more defined physique. 

One area where most people will focus is their biceps.

Having more prominent and more muscular biceps helps you develop the perfect physique, which is why many focus on these muscles.

If you want to build strength in your biceps, you could do either the dumbbell curl or the barbell curl.

Both exercises are pretty popular, and you may even be doing both.

However, many people often ask which training is best: the barbell curl vs. the dumbbell curl?

Before looking at which one is better, let’s look at the dynamics and benefits of each exercise.

Barbell curl

The barbell curl is done with a barbell and both hands.

Unlike the dumbbell curl, you only need a single barbell to work both arms.

The barbell curl allows you to lift more weight as you progress during your workouts.

It is also a single motion which means that you will target both arms evenly.

The barbell curl might be difficult for some to master, although it’s a pretty simple exercise.

The barbell curl is quite effective in building strength in the biceps and shoulders.

If you are looking to start powerlifting, then you should try to do more barbell curls.

You’ll often notice that powerlifters do more barbell curls as compared to bodybuilders.

Dumbbell curl

The dumbbell curl is a unilateral movement which means that each hand will be lifting the weight separately.

The dumbbell curl is the most popular exercise for developing biceps.

It involves gripping the dumbbell in one hand and curling it upwards without moving the shoulders.

Dumbbell curls are also great for developing strength in the biceps and help you get more toned-down muscles.

Dumbbell curls are usually used in bodybuilding, and the focus is on developing the perfect muscle shape.

Pros and cons of barbell curls 

Pros 

  • It is excellent for developing strength.

Cons 

  • Uncomfortable

Holding a barbell with both hands can only be done with the palm facing inward.

It causes an unnatural wrist position, which may be uncomfortable.

If you are prone to wrist injuries, then it might not be easy.

However, having your wrists in this position can also strengthen it.

  • Targets specific muscles only 

Doing barbell curls is excellent, but only for developing specific muscles.

The bar causes a limited range of motion, which makes it a one-dimensional exercise.
