An advanced kettlebell program by Mark pro trainer Mark Shropshire. This program is used to train tier one athletes and hard chargers who are not satisfied with the normal tenets of training and getting normal results. At times, this program will challenge you. Make no mistake about it. It is designed using tried and true scientific principles of strength training and physiology. Add in a heavy dash or two of 20 plus years of experience in the gym working with REAL people and you have yourself a program that is fool proof and effective.
