PowerBlock vs. Ironmaster Adjustable Dumbbells: The Showdown (2025)
Author: Cooper Mitchell, GGR Founder
I love a good showdown between two pieces of the best home gym equipment. It makes me feel like I'm John Cena or in the WWE. A man can dream, ok? Anyway, I’m sharing with you, the lovely readers of Garage Gym Reviews, my thoughts on two of the best adjustable dumbbells in the game: the Ironmaster Quick-Lock Adjustable Dumbbells and the PowerBlock USA Elite Series Adjustable Dumbbells.In this showdown, you’ll hear my thoughts on the great Ironmaster vs. PowerBlock debate and what I think you really need to know. Neither of these products are exactly monetarily equivalent to picking up a sausage biscuit at McDonald’s, so I know you want to get this purchase right. I’ll help by giving you all the details on price, warranty, customer reviews, and workout experience.
