Original Russian Kettlebells offer high-quality kettlebells (not surprising there!) in a cast kettlebell finish and a competition steel kettlebell finish. The former being favoured for general use, whereas the purist and clubs prefer the one-size increments of the steel competition kettlebells. In our own facility, @thegym, the steels competition kettlebells are favoured by gym-goers from 20kg and upwards, whereas for 16kg and below, our soft-shell studio kettlebells are the big favourite. From a club owner POV, the latter also look better for much longer, so we recommened the soft-shell studio kettlebells for most gym environments, whether that's home gyms, garage gyms, personal training, or gym clubs.
