I've been training with kettlebells for a couple of years now. It wasn't until the last couple of months that I had the chance to train with Corey Padnos who is an expert on kettlebell technique. Our approaches to training people on proper technique within our respective domains are nearly identical.
I was mostly training with kettlebells on my own. I did my best to get my technique in order, but I knew that there was a lot of room for improvement. When I started training with Corey, the first thing he did was cut both the intensity and the volume of my workouts, and focused on technique. That's exactly what I do when I work with runners. Cool!
As a running coach, I've had my share of struggles getting runners to put their egos aside, so I let Corey be the coach. I accepted his directions, and asked questions as needed. It was frustrating at times to go through what seemed to be ridiculously easy workouts as well as going through the process of relearning my technique, but I understood that it is a necessary step and that there are no shortcuts. Ultimately, Corey's changes to my technique, paid off well. I can move faster and go longer despite the reduction in my training volume and intensity. The runners I work with, who follow my direction, have this experience as well. The bottom line is that technique matters. Get it right, and everything else falls into place.
