There are six foundational techniques in the RKC: the Swing, Squat, Clean, Press, Snatch and Turkish Get-up. That's it - but in reality it's quite a lot. Unfortunately many trainers and users think that they need to "jazz" things up to make the Kettlebell more effective - but this is far from the truth. Can you imagine doing some of the crazy stuff people do with a Kettlebell with a bar instead? Not only would it be comical but potentially suicidal! Study the basics until you can execute them flawlessly... and then keep working on them.
Listen to what is being presented in this video about the importance of the Kettlebell Swing and how it reverses a lot of the damage we do to our bodies outside the gym.
