As strongman training methods become more and more popular (YAY!), newbs are being exposed to implements and movements that they've never done before - which is AWESOME! However, just like any new skill, you must understand the concepts and techniques, then apply quality practice - especially when first introduced.
In an effort to help some of you strongman newbs dial in your atlas stone technique, this video is all about performing the stone shoulder smoothly rather than rushing through it with reckless abandon.
In general, it is my opinion that performing any movement with fluidity will increase your overall speed. This is especially true with the atlas stone. Just remember: Smooth is Fast!
