Dumbbell drag curls are a great drill for building up the biceps brachii. Unlike regular drag curls, the DB drag curl ensures that both of your arms receive equal work because you have to move each limb independently. This helps you to develop a more symmetrical upper body and a more aesthetic physique.

Dumbbell drag curl pros and cons
Performing the drag curl dumbbell style definitely has its advantages and disadvantages. For example, dumbbells create fewer muscle imbalances than barbells, but they don’t allow you to lift as much weight.
Pro: Symmetrical biceps
When you perform drag curls with an EZ bar, there’s always the chance that your stronger bicep will dominate the movement. This, in turn, leads to the development of muscular imbalances or worsens the discrepancies in size and strength that your arms might already have. 
Performing a drag curl with dumbbells is the solution because both of your arms have to lift the exact same amount of resistance. After all, it’s not like your stronger bicep can help your weaker bicep lift the weight—it’s already preoccupied with hoisting its own dumbbell!
You can take this a step further by purposefully thinking about squeezing your biceps (especially on your weaker side) on every rep. This mind-muscle connection will help you to ensure that your biceps are getting the most stimulation from every rep, which results in greater hypertrophy over the long run.
Con: Need to use less weight
Unlike the Smith machine drag curl, which naturally lends itself to lifting heavy weights because you don’t need to stabilize the bar, you have to go pretty light on drag DB curls to get the most from the movement.
This is mainly because you can’t use as much resistance when your brain has to focus on lifting two separate weights. The trade-off, of course, is that dumbbells provide better muscle isolation because you can more easily focus on stretching and squeezing each individual bicep.
So even though your biceps won’t be receiving as much resistance when you perform the drag curl dumbbell style, you can compensate for this by putting effort into your mind-muscle connection, which will help to increase your bicep activation.

Pro: More convenient
If you do reverse grip drag curls or any exercise that uses a barbell, then there are no two ways about it: You’re going to be spending more time in the gym.
With barbells, you have to locate the correct weight discs, then you need to make sure that you load each side equally. And, most frustratingly of all, you need to hunt down a pair of collars. Not exactly what I’d call convenient.
But with the drag dumbbell curl, you just grab a pair of weights and lift. It’s that simple.
While all of this might not seem like a big deal if you’re a bodybuilder, not everyone enjoys living in the gym.  So if you can save five minutes on multiple exercises, then your training sessions are suddenly going to seem a lot less intimidating time-wise.
Con: Harder to gain strength
The main downside of the dumbbell drag curl is that you can’t increase the weight all that frequently because the resistance typically increases in 5lb increments. This is a surprisingly large weight jump for a relatively weak muscle like the biceps, so it can be frustrating to lift the same old dumbbells for weeks on end.
If you train at home and only have basic equipment, then you also give the banded drag curl a try.
Should you do drag curls with dumbbells?
If you want to sculpt proportional biceps and work on your peaks, then dumbbell drag curls are one of the best exercises for the job. Not only does the dumbbell drag curl work your biceps evenly, but it’s also a much more convenient movement to execute than something like drag cable curls, which is especially true if you train at home.
Make sure to get a full range of motion if you want to take full advantage of this exercise, and try not to shrug the weight up with your traps if you can help it. Mentally thinking about decreasing the distance between your lower arms and your biceps will help to keep the tension on the target area.
