Strengthspan: Building Strength for a Healthier, More Independent Life

How many of your later years will include carrying luggage, climbing stairs or playing golf? Strengthspan shifts attention from years lived to the strength that helps make those years active. Amy Hudson and Dr. James Fisher discuss a lifespan framework that connects early strength habits, adult health and older-age function. They also explain why associations between strength and health are relevant even for people who do not regularly run or play sports.

Aging-related strength loss may not follow a smooth downward slope. Fisher uses his knee injury to illustrate how a single event can reduce physical capacity, and why both strength built beforehand and rebuilding afterward matter. The conversation closes with a practical comparison: retirement savings support the lifestyle you want financially, while maintaining strength helps support it physically. You do not need to have been athletic as a child to begin.
