Powerblock vs Ironmaster Dumbbells - Which is Better?
Free weights are important when you intend to increase your strength and muscle mass. One of the most versatile free weights you can own and use at home are dumbbells. They allow you to target big and small muscles in your body, helping you achieve the strength, tone, or bulk that you are aiming for.
All you need is a pair of adjustable dumbbells, instead of a huge row of fixed ones. The fixed dumbbells are great when you are in the gym because you can grab what you need from the rack. At home where space isn’t a luxury, adjustable dumbbells give you the freedom of having multiple weight choices in one pair.
Product Overview: PowerBlock vs. Ironmaster
The PowerBlock brand has three different models to suit all levels, and they all have the same sliding pin mechanism that makes changing weights quickly.
All the Powerblock dumbbells are made from welded steel plates, but there are parts that are made of durable plastic.
The steel components can handle some weight and dropping, but you have to treat the PowerBlock dumbbells with care (1).
Ironmaster Dumbbells are famous for the durability of their adjustable dumbbells. The dumbbells have their patented quick-lock system to lock the weight plates.
Ironmaster boasts that their dumbbells are made of solid iron and steel, and they will not break easily. It comes with a lifetime warranty to support that claim.
Their lock system is similar to the spinlock system, but the screw pins hold the weight plates tighter making it less prone to be loose over time.
The weight plates from the dumbbells are also compatible with their kettlebells if you are looking to expand your home gym. (2)
