Frequently Asked Questions
Are coated kettlebells better than plain cast iron?
Coatings (enamel or powder) protect against chipping and rust and often give a smoother handle feel, which many lifters prefer. Plain cast iron can offer more raw grip but requires more maintenance to avoid corrosion.
Which handle finish is best for high-rep swings and snatches?
A smooth, slightly rounded handle with a consistent finish (like the premium enamel/powder finish) reduces hotspots and allows easier transitions for snatches and cleans. If your hands sweat, use chalk or grips, since smoother finishes can feel slippery.
How should I prevent coating damage on budget kettlebells?
Use a rubber mat when placing kettlebells on hard floors, store them off damp concrete, avoid dropping them from height, and wipe them dry after sweaty sessions. These steps greatly extend the life of budget finishes.
