Cardiovascular fitness - commonly known as cardio - is the cornerstone of a healthy and active lifestyle. While strength, flexibility, and body composition are all important components of physical health, none are as critical as the body’s ability to transport and use oxygen effectively. Whether you're training for a marathon, trying to keep up with your kids, or simply aiming to feel better day-to-day, cardio is the key to long-term vitality.

What makes a fitness program truly effective? The answer isn’t one-size-fits-all. Whether you’re a beginner, weekend warrior, or elite athlete, the definition of physical fitness should be flexible enough to meet your current and future physical demands. In essence, physical fitness is the body’s ability to successfully handle life’s physical challenges - both routine and unexpected.
