The double arm alternating kettlebell snatch is, in my opinion, one of the most challenging kettlebell exercises. In the above video, my kettlebell instructor Pavel Stejskal performs a set of this difficult kettlebell snatch variation.
This exercises takes on an interesting combination of strength, coordination and timing. When performed correctly the exercises takes on a rhythmic hopping motion. The biggest challenge of this exercises is getting enough momentum to drive the down kettlebell up while accepting the weight of the other kettlebell as it drops into the down position.
