Iron Will is a dumbbells-based workout that will help your body develop strength, stability, coordination and power through a series of resistance exercises. The activation of the body's back and front kinetic chains and its core delivers performance benefits way above the difficulty level of this workout. This is one to keep in mind for the days when you want to reach for those dumbbells you have lying around.
Extra Credit: Use 8kg+ (16lb+) dumbbells.
