EZ Curls, Powered by Dumbbells, and Dualbells

A Smarter Way to Train Arms at Home

EZ curls have long been a staple for building arm strength. The angled grip of an EZ curl bar reduces strain on the wrists while allowing lifters to focus on bicep engagement. Traditionally, though, EZ curls come with a familiar tradeoff: plates, storage, setup time, and cleanup.

For home gym owners — especially those training in limited space — that friction adds up.

That’s where Dualbell, a patented dumbbell-to-barbell converter, changes the workflow entirely.

Turning Dumbbells Into Barbell Weight

In this setup, dumbbells are used as the weight source on an EZ curl bar instead of traditional plates. With Dualbell, each dumbbell slides into a secure shell and mounts onto the bar, allowing the dumbbells to function exactly like weight plates — but with far more flexibility.

The result is an EZ curl setup powered entirely by dumbbells.

This approach makes it possible to move seamlessly between:

• Barbell-style EZ curls

• Quick weight changes

• Standard dumbbell curls

…without ever touching a plate rack.

Easy Weight Changes, Minimal Downtime

One of the biggest advantages of using a dumbbell converter like Dualbell for EZ curls is how quickly weights can be adjusted.

In the video, the first set is performed using 20 lb dumbbells, followed by a simple swap to 25 lb dumbbells for the next set. That 5 lb change per side adds 10 lb total to the bar — with no plates to strip, no collars to juggle, and no clutter on the floor.

For lifters who train with ramping sets, drop sets, or density-style workouts, this kind of efficiency matters. Less time between sets means more focus on the movement and less disruption to training flow.

No Plates, No Cleanup

Another overlooked benefit of using dumbbells as barbell weight is what happens after the set.

When EZ curls are finished, the dumbbells can immediately be removed from the bar and used for:

• Standard dumbbell curls

• Hammer curls

• Concentration curls

• Supersets without resetting equipment

There’s no need to unload plates, re-rack them, or reorganize the space. In a small home gym, that simplicity makes a real difference.

This is where Dualbell stands out from other dumbbell converters — it’s designed not just for strength, but for real-world training efficiency.

Why This Matters for Home Gym Training

Many home gym owners rely heavily on dumbbells because they’re versatile, compact, and easy to store. The downside has always been the gap between dumbbells and barbell movements.

Dualbell bridges that gap.

By allowing dumbbells to function as barbell weight, it expands what’s possible with the equipment people already own. EZ curls are a perfect example: a classic barbell exercise made more flexible, more space-efficient, and easier to manage.

Instead of choosing between dumbbells or a barbell setup, a dumbbell converter allows you to use both — often in the same workout.

A Smarter Arm Workout

EZ curls powered by dumbbells aren’t about reinventing the exercise. The movement stays the same. The muscle stimulus stays the same. What changes is the experience around it:

• Faster setup

• Easier progression

• Less equipment to manage

• More flexibility within a single session

For lifters training at home, especially those without room for full plate storage, this approach offers a practical, effective alternative.

The Takeaway

EZ curls don’t need plates to be effective.

With Dualbell, dumbbells become a modular, adjustable weight system that works seamlessly on an EZ curl bar. Weight changes are quick, cleanup is minimal, and the same dumbbells can immediately be reused for other exercises.

That’s the real value of a well-designed dumbbell converter: not just adding exercises, but improving how training flows in a home gym.
