In his insightful new book Grip Strength, author Kevin B DiBacco spotlights the critical importance of grip strength as a harbinger of total body power and future health. As the masterful coordination between small muscles and tendons that allows the hands to grasp objects, grip strength serves as more than just the strength of our palms and fingers. DiBacco explains how grip provides a window into overall muscular and physiologic reserve across ages. Citing recent studies, the book details how tracking grip strength changes over time predicts risks of developing mobility limitations, chronic diseases, dementia, and even early mortality. By enabling readers to easily test and monitor their own grip, DiBacco provides actionable strategies involving lifestyle factors and targeted training to uphold this vital indicator of strength essential for actively engaging in occupational, recreational, and daily activities long into the aging process.
