Want bigger biceps that visibly pop under your sleeves? Thankfully, building bigger arms isn’t challenging. In this article, I’ll go through the best dumbbell bicep workout that targets each part of your biceps, so you add the muscle mass you want to your arms.
If you’re looking to get bigger biceps, you need to incorporate enough bicep exercises with dumbbells into your workout routines. But – why free weight?
Well, unilateral exercises better help prevent muscular imbalances. Also, dumbbell bicep exercises allow you to tweak ‘traditional’ bicep exercises for exponential biceps growth in ways that cannot be achieved with the use of barbells.
So, if you’d like to find out how an intense dumbbell bicep workout can boost your biceps growth, do stick around.
I’ll be covering the best bicep curl exercises with dumbbells you need to add the size you want. If you only have access to dumbbells, please continue reading too. You’ll find tons of value for your regular dumbbell bicep workout here.
Before that: if you’re looking for a training program that’ll help you set up every single one of your workouts for optimal muscle growth (not just for the biceps, but for ALL muscle groups!), I’ve got just the thing for you. Every BWS program is designed to be an all-in-one, science-based process that’ll get you to your dream physique FAST. And best of all? It’s all rooted in science. For more information:

1) Concentration Curl (With Assistance Reps)
As you probably already know, you can favor the inner part of your biceps more by placing your arms slightly in front of the body during the curl. Therefore, when it comes to short head bicep exercises, dumbbell concentration curls top the list.
And it doesn’t just target the short head portion of your biceps either. According to the following two EMG analyses (ACE and SuppVersity), it tends to outperform other common biceps exercises in terms of eliciting the highest biceps activation.
Why? The researchers speculate that when you have your upper arm pressed against your leg, you’re unable to sway your arm as you curl. As a result, you’re forced to initiate the movement with your biceps, rather than momentum.
The movement restriction also minimizes the involvement of your front delts during each rep. You’re, therefore, able to better isolate the biceps, leading to enhanced muscle activation. Which explains why it’s a must-have in any well-programmed dumbbell bicep workout.
However, there are a few critical points to take note of to maximize concentration curl’s effectiveness.
#1 – Grip the outer part of the dumbbell
You can maximize the activation of the biceps’ short head by combining the flexion of the arm with the supination of the wrist.
But why am I so sure? Take a look at this EMG analysis.
So how does this translate to your training? You’ll want to turn your wrist out to bring your pinkies toward the ceiling as much as possible.
And to take this one step further for even more bicep gains, you can grip the outer part of the dumbbell instead of the middle. This grip alteration will shift more weight into the pinkies of your hands.
There’ll be a resulting increase in the degree of active supination needed to curl and twist the wrist. And we know what that means. More significant involvement of the biceps’ short head, leading to a more intense dumbbell bicep workout!
#2 – Perform assisted reps
After your regular set is complete and you can no longer perform additional reps, don’t stop. You’re not done with your dumbbell bicep workout!
You can continue the set by performing a few more reps with assistance from your non-working hand during the concentric part of the curl. Then, slowly let the weight down without aid during the eccentric movement.
According to an EMG analysis, assisted reps can significantly boost the activation of biceps by enabling you to continue working with a weight you otherwise would not have been able to.
2) Incline Dumbbell Curls
Excellent. You now know the best exercise in a dumbbell bicep workout to target the bicep’s short head. What about long head bicep exercises? Well – as many of you know, the incline dumbbell biceps curl is one of my favorite biceps exercises to build biceps peak. And as it turns out, this exercise tops the list for seated dumbbell biceps curls that target long head bicep growth.
As you should know, you can preferentially target the long head of the biceps by placing your arm behind the body when performing a curl due to its anatomy. In addition to enhanced long head activation, the incline dumbbell curl also wins out other biceps exercises in its unique strength curve. A crucial player in any dumbbell bicep workout.
According to a paper from the Journal of Sports Science and Medicine, the incline dumbbell curl elicits a relatively high neuromuscular activation of the biceps throughout each phase of the curl. This sustained activation is in stark contrast to other biceps exercises, where the biceps are best activated in the beginning, or the end of the movement.
Incline dumbbell biceps curls’ activation advantage, therefore, leads the researchers and me to recommend it as one of the best outer biceps exercises.

However, its effectiveness depends on how you execute the exercise – as with all exercises. Here are some key points to keep in mind.
#1 – Lock your elbows
Keep your elbow pinned and locked in place; this minimizes any front delt involvement. Undoubtedly, you’ll fatigue during an intense dumbbell bicep workout.
So a few degrees of elbow movement is all right, but it should not be excessive to the point where your delts begin to take over.
#2 – Keep shoulder-blades pinned back
You don’t want to cheat by rolling the shoulders forward. Doing so reduces the range of motion that you put your biceps through, and you may start to involve the traps as well.
Instead, keep your shoulder-blades pinned back as you perform each rep. Maintain this posture even when you begin to fatigue; you’ll minimize the tension placed on unwanted muscle groups and maximize the growth of your biceps.
3) Hammer Curls With Slow Eccentric
Lastly, I’m going to cover one of the key exercises in a dumbbell bicep workout – the dumbbell hammer curl. You may be wondering, “Hammer curls vs. bicep curls – what’s the difference?” Well, the hammer curl targets the brachialis. It’s a key exercise to include in any well-rounded dumbbell bicep workout. In addition to being responsible for the mass of the outer arm, the brachialis also anatomically pushes up the biceps.
This ‘push-up’ action helps you create the illusion of a more full and thicker-appearing arm.
How can you achieve this much-coveted illusion? By effectively targeting the brachialis, of course. And you can do so by playing around with your grip through hammer curls.
Due to the anatomy of the biceps, as the degree of pronation increases – and the biceps tendon winds more around the radius – the potential for maximal force development decreases. And the brachialis is forced to take over as a result.
Accordingly, if you were to grip the dumbbell with a more pronated grip (like holding a hammer), you’d direct the tension towards the brachialis, instead of the biceps.
According to a 2001 paper from the American College of Sports Science, you can further enhance the involvement of the brachialis by slowing down the eccentric portion of the curl.
What does this mean for your arms training? Well, if you want bigger-looking arms, you can’t go wrong with implementing a 5-second slow eccentric during the way down for each rep. You’ll be able to isolate the brachialis to a much greater extent.
Putting It All Together: Best Bicep Workout With Dumbbells
So, here’s a quick summary of the bicep curl exercises with dumbbells I went through. Each of them targets a specific portion of the bicep – long head, short head, and outer bicep.
Sample dumbbell biceps workout
If you’re planning to incorporate them into your very own dumbbell bicep workout, here’s the recommended sets and reps.
- Concentration Curls: 3-4 sets of 6-12 reps (+ 3-4 assisted reps)
- Incline Dumbbell Curls: 3-4 sets of 6-12 reps
- Dumbbell Hammer Curls: 3-4 sets of 6-12 reps (with 3-5 seconds eccentric)
Feel free to do this as a workout on its own or split it up, and add one or two of the exercises to your existing routines.
I would also suggest playing around with the order of the biceps exercises. Why? Well, because we know that lifters typically experience more significant gains for exercises done early on in a workout.
So – if your long head or outer bicep, for example, is noticeably lagging in comparison to your short head or inner bicep, you can perform the incline dumbbell curls first. This way, you’ll prioritize your long head’s development.
With optimized programming in a dumbbell bicep workout, you’ll see more balanced biceps growth in the long run.
