**Introduction to Fit at 50** is a 50-minute lecture on the importance of maintaining fitness as the body ages. It examines how regular physical activity supports strength, mobility, cardiovascular fitness, balance, endurance, and functional independence, while addressing the physiological changes that make fitness increasingly important in the years after 50.

The lecture introduces the fundamental components of fitness and explains how exercise can be adapted to meet the changing needs of adults as they age. Participants will gain a practical understanding of why maintaining muscle, mobility, cardiovascular capacity, balance, and overall physical activity can contribute to maintaining performance and quality of life throughout later adulthood.
