My workouts include aerobic exercise for a healthy cardiovascular system strength training to maintain muscle tone and bone density core strength exercise for a stable mid-section and stretching to maintain mobility.

Stosur outlines a balanced, evidence-based approach to athletic conditioning: endurance work to support heart and lung capacity, resistance training to preserve strength and skeletal health, targeted core work for stability and injury prevention, and flexibility training to maintain range of motion. The quote reflects a modern “total fitness” philosophy in which performance and longevity depend on multiple physical systems rather than a single metric like stamina or power. It also implicitly frames training as preventive medicine—protecting bones, joints, and mobility—an emphasis especially relevant for elite tennis players managing repetitive load and long competitive seasons.
