I feel that one of the most difficult kettlebell movements to learn is the kettlebell clean. The kettlebell clean should build off the single arm swing. During the single arm swing the upper arm should extend out in the parallel position and during the clean it should stay close to the body, and this is where the problem occurs. I’ve been fooling around with way to make the learning process simpler and I came up with crossing your opposite arm over the upper arm and performing the clean. This forces the upper arm down, keeping it close to the body and the clean smooth.
