Steel Kettlebells: Are They Worth It?
Lately, some kettlebell manufacturers have been advertising steel kettlebells. Often, they use marketing terms like pro grade, competition, or regulation to further hype up their products.
But what’s the real story? Are steel kettlebells something you should look into, or is it just more hype?
Basically, the difference between cast iron and steel is meaningless. Steel is iron with some impurities added to it during the smelting process. These impurities change the crystal structure of the metal and, in the case of steel, make it harder and/or more rust-resistant.
The type of metal isn’t important, but the shape may be.
In the case of competition kettlebells, what the dealers are saying is that all their bells — regardless of actual weight — are the same size. To achieve this, they make the bells semi-hollow.
This distinction isn’t important unless you plan to compete in kettlebell competition. Then, you may benefit from training with kettlebells that are all the same size and shape.
So, unless you are a hardcore kettlebell athlete with dreams of competition in your future, you don’t need to pay a premium for a steel kettlebell. Traditional cast iron bells are fine. Better yet, get an adjustable kettlebell because, as you probably know by now, adjustable kettlebells outperform traditional kettlebells.
