Best kettlebells for natural training
Cast iron bells versus competition bells, using two Rogue pages that print handle and size differences.
Picks are not paid placements. We may earn a commission on some links.
There is no single best kettlebell. The right bell depends on whether you want the handle to stay the same as the weight goes up.
Specs below are from Rogue's own pages, checked on 22 October 2026. Prices and star ratings are left off.
Cast bells
The ductile iron Rogue kettlebell runs from 9 lb to 203 lb. Handle diameter moves from 1.19 in to 1.73 in as the bells get heavier. The base is flat, which matters if you park the bell to press it. The page says they are made in the USA.
Competition bells
The competition kettlebell stays 11.1 in tall with a 5.5 in base and a 33 mm handle from 8 kg through 48 kg. That is the point of the style: the weight changes, the shell does not.
Rogue's spec table marks Made in USA as No for this model. We are not guessing where they are made beyond that.
