One of the greatest lessons that kettlebell training provides is the "interconnectedness" your body and mind develop. Most novice lifters have very little body awareness and proprioception. They have no "body flow." Like a martial artist, gymnast, or other highly trained athlete, frequent kettlebell training develops a person's ability to utilize their body in dynamic and fluid ways, showcasing their power, strength, and mobility all in one.
This is particularly important in daily life tasks. Imagine if you stumbled on the curb and just abruptly plummeted face first while trying to brake your fall with your hand. The emergency room visit to repair the broken bones, lesions, and tissue sprain would be quite expensive and painful. Instead, imagine that same fall, but you learned to redirect your body on its side, tucking and rolling on impact, absorbing the energy through your core and hips. You would simply brush yourself off and laugh at how disastrous the episode could have been!
The kettlebell figure 8 teaches you that necessary proprioception and body flow. You learn to combine rotary torsion with hip extension, while redirecting energy from your legs to your arms. It take some time to get the coordination of the movement down, but you'll get it. Now get to work!
