Built for the years that matter most
PRIME 40 was created for adults who want to stay strong, capable and healthy well beyond 40. The goal is simple: bring the major pieces of lifelong fitness into one practical reference so readers do not have to piece together conflicting advice from dozens of sources.
The book combines evidence-based guidance on resistance training, cardiovascular fitness, nutrition, blood work, body composition, recovery, supplements, injury risk reduction and long-term health. It is written to be useful whether you are returning to training after years away or already experienced and looking for a more structured approach.
One reference. The full picture.
PRIME 40 is designed as both a start-to-finish guide and a reference you can return to. Rather than chasing trends, it focuses on the principles that consistently matter: progressive training, appropriate nutrition, useful health monitoring, sufficient recovery and intelligent adjustments over time.
