Over the years I have had the benefit of watching so many participants improve and as a teacher there's not much that makes me happier than watching my students get comfortable with my program.
Regardless of how long it has taken, something that is always constant with proper Kettlebell training is that people do get stronger. But, to be honest, I do have to say that this does not always come with an easy task.
Train safely, effectively, and stay healthy and your ability is bound to improve. Guaranteed!
