What type of kettlebell should you buy? Cast iron vs. competition and more
Short answer
For training at home, the best choice for most people is a cast iron kettlebell with a smooth handle and flat base: it's durable and cheaper. Competition kettlebells (steel, same size at every weight) make sense for high-rep technical work or if you own several. Adjustables save space but feel different in swings.
Quick comparison
| Type | Pros | Cons |
|---|---|---|
| Cast iron | Durable, affordable, thick handle comfortable for swings | Size changes with weight |
| Competition (steel) | Same size and handle at every weight; consistent technique | Pricier; thinner handle |
| Vinyl / rubber coated | Protects floors, quieter | Less durable; coating can tear |
| Adjustable | Several weights in one bell; saves space | Pricier and feels different in swings and cleans |
Which one fits you?
- Starting out at home: cast iron.
- High reps or building a set: competition.
- Delicate floors or neighbors below: cast iron with a rubber base or a good mat.
- Short on space with a bigger budget: adjustable.
