One of my clients asked me if you can curl a kettlebell for biceps. Yes you can if…
Whats the if? It depends if you have strong wrists in the first place. A beginner to resistance training would practice with dumbbells or barbells first in order to lesson the risk of injury to the wrist ligaments or tendons.
The reason is that curling a kettlebell places additional stress on the plantar tendons of the wrist as the bell moves higher. The hand wants to dorsal flex away from the body to counter react to the leverage disadvantage the odd kettlebell weight creates. (video below)
It is very important to lock your wrist when curling the kettlebell. If you find your starting to dorsal flex the wrist, simply lower the kettlebell weight.
A beginner might want to start with 12kg bell.
With that said, your biceps will truly benefit from the additional stress the kettlebell will make on the muscles.
