“Is This for Real?” A Trainer’s Honest Take on Dualbell

A Personal Trainer Reacts After a Full Trial

When experienced trainers react to new equipment, their first instinct is usually skepticism. They’ve seen trends come and go, gimmicks promise too much, and shortcuts fall short of real training demands. So when NYC personal trainer Michael Marguilies paused after his session and asked, “Is this for real?”, it wasn’t doubt — it was surprise.

What followed mattered even more.

“It’s not a gimmick. It’s the real deal.”

That reaction came after Michael put Dualbell, a patented dumbbell-to-barbell converter, through a wide range of exercises: squats, bench press, deadlifts, overhead press, landmine work, rows, and rotations. The quick 12-second video snapshot captures that moment of realization — when something stops feeling experimental and starts feeling legitimate.

From Dumbbells to a Real Gym Feel

One of the biggest challenges for home gym training has always been recreating the feel of a commercial or Olympic-style gym without dedicating the space, budget, or storage required for full plate systems.

Dumbbells are versatile and compact, but they traditionally limit certain movements. Barbells offer load and structure, but they often demand plates, racks, and room to operate.

Dualbell bridges that gap.

By converting dumbbells into functional barbell weight, this dumbbell converter allows lifters to perform classic barbell movements using equipment they already own. For Michael, the surprise wasn’t just that it worked — it was how quickly it felt natural.

“That real Olympic lift feeling… that real gym feeling,” he said.

Why “Not a Gimmick” Matters

Calling something “not a gimmick” might sound simple, but coming from a trainer with decades of experience, it’s significant. Gimmicks usually announce themselves quickly. They feel awkward, unstable, or distracting. They pull attention away from the lift instead of enhancing it.

Throughout Michael’s trial, the opposite happened.

Whether it was bench pressing with subtle instability that reminded him of a tsunami bar, landmine rows with increased range of motion, or rotations that activated his core more deeply, the feedback stayed consistent: the setup added value without changing the exercise itself.

That’s the difference between novelty and utility.

The Value of a Well-Designed Dumbbell Converter

A dumbbell converter shouldn’t just add exercises — it should improve how training flows. Dualbell does that by reducing friction between sets, minimizing setup and cleanup, and allowing seamless transitions between dumbbell and barbell-style movements.

That’s why Michael’s reaction landed the way it did. The realization wasn’t about a single rep or exercise. It was about how the entire session felt.

Efficient. Familiar. Effective.

A Snapshot That Says It All

The 12-second clip doesn’t try to explain every detail of the system. It doesn’t need to. It captures the moment when a seasoned professional stops analyzing and starts nodding.

“Is this for real?”

Yes — and that’s exactly why the reaction matters.

For home gym owners looking for a smarter way to train without sacrificing the feel of real lifting, that question — and its answer — may be the most honest endorsement possible.
