How they stack up

Core Adjustable Dumbbells

The Core Adjustable Dumbbells offer the fastest adjustment mechanism compared to the Bowflex Results Series 552 SelectTech Dumbbells, which have a more complex dial system. However, unlike the PowerBlock Elite, it lacks the USA-made construction and magnetic selector. The Core also provides less precise weight increments than the SMRTFT Adjustable Dumbbell, which offers a wider weight range and more advanced features.

MX Select MX55 Rapid Change Adjustable Dumbbells

The MX Select MX55 Rapid Change Adjustable Dumbbells offer the fastest weight transitions compared to the Core Adjustable Dumbbells, which require a twist mechanism. However, it's more expensive than the Core and lacks the wide weight range of the Yes4All Cast Iron set. Unlike the SMRTFT Adjustable Dumbbell, it provides a more compact design but has a narrower weight selection and is less durable than the PowerBlock Elite.
