Why Do Dumbbells Move When Using Dualbell?

If you've watched a Dualbell video closely, you may have noticed something: the dumbbells aren't always completely motionless.

They can move or rotate somewhat as the bar moves.

At HomeGymCon, one person noticed it almost immediately while trying Dualbell on the bench press.

“Initially, it feels a little wobbly,” he said.

But he kept lifting.

As he became familiar with the movement, he compared what he was experiencing to a training technique he already knew — suspending weight from bands to deliberately introduce movement during an exercise.

His observation raises a good question:

Why can a dumbbell move when it's being used with Dualbell?

Dualbell Holds a Dumbbell Differently Than a Weight Plate

A traditional weight plate is centered directly around the sleeve of a bar.

Dualbell works differently.

A compatible dumbbell is secured within the Dualbell converter, while the Dualbell itself slides onto a standard 1-inch bar. The dumbbell therefore becomes the source of resistance for the barbell exercise.

That configuration allows the dumbbell some natural movement and rotation as you lift.

Seeing that movement doesn't necessarily mean one side of the bar suddenly weighs more than the other. The weight of the dumbbell hasn't changed simply because the dumbbell has rotated.

The lifter still needs to control the bar and the movement of the resistance throughout the exercise.

Movement Isn't Something We Need to Hide

When people first see Dualbell, it's understandable that they sometimes expect the dumbbells to remain perfectly fixed.

But Dualbell wasn't designed to turn the dumbbell itself into a conventional weight plate.

It was designed to let you use the weight you already own in another way.

That difference is important.

The dumbbell can naturally move during certain exercises, and the amount and type of movement can vary depending on the dumbbell, exercise, loading and how the lift is performed.

Rather than pretending that doesn't happen, we'd rather show people what using Dualbell actually looks like.

A First-Time Reaction at HomeGymCon

That's what made this particular HomeGymCon reaction interesting.

The person trying Dualbell didn't simply perform a few bench press repetitions and tell us he liked it.

He noticed something unfamiliar.

He talked about it.

Then he continued lifting and related the sensation to something from his own training experience.

His comparison to weights suspended from bands was his observation, not a claim we're making about Dualbell or a statement that the two training methods are equivalent.

But it's exactly the kind of unscripted reaction we wanted by bringing Dualbell to HomeGymCon.

People could see it, touch it, load it and decide what they thought for themselves.

Natural Movement. Another Way to Use Your Dumbbells.

Dualbell dumbbell to barbell converters were created to give home gym owners another way to use equipment they may already have.

Compatible traditional or adjustable dumbbells can provide resistance for exercises including bench presses, squats, deadlifts, rows, curls, overhead presses and landmine movements.

When you're finished, remove the dumbbells from Dualbell and they're still dumbbells.

Same weight. More ways to put it to work.

And yes — sometimes those dumbbells like to move a little.

Maybe that's another reason I keep saying:

My dumbbells like rock n' roll. 🤘
