In CrossFit, we’ve seen the Kettlebell as something to swing overhead and in some cases, pick up and carry to the other side of the room. We certainly get a lot of benefits from these two movements, but Kettlebells do have other purposes & benefits.
The Kettlebell Sportstyle Swing is always done with one arm, never with two arms like you see used with the swing that most people are used to, the conventional kettlebell swing. There is a very valid reason why Sport Athletes don't do the sportstyle swing with two arms, and that reason is; it doesn't transfer to anything in the sport, i.e. Snatch, Clean or Jerk. Every kettlebell exercise used in competition is performed with one arm, hence there is no reason to do the sportstyle swing with two arms.
