Kettlebell RX: The Complete Guide for Coaches, by Jeff Martone. 320 pp. Victory Belt Publishing. $34.95.
Jeff Martone is the CrossFit kettlebell subject-matter expert and creator of the CrossFit Kettlebell Trainers Course. He knows kettlebells.
Martone’s book is divided into three parts, the first dedicated to CrossFit athletes and coaches. In this regard, Kettlebell RX can be defined as a supporting manual to his CrossFit Kettlebell course: it’s an extensive and detailed resource for the nuances of adopting into one’s programming an assortment of new movement patterns using a kettlebell.
I think Kettlebell RX will mostly appeal to CrossFit trainers in need of a reference source for refining proper mechanics with a kettlebell and more advanced CrossFit athletes who have a solid understanding of fundamentals. It will also offer coaches options on kettlebell exercises to keep their programming “constantly varied.”
