Tennis takes care of everything. It requires agility and quickness to get to the ball, core strength to get power into your shorts and stamina to last for an entire match. In addition to toning your arms and shoulders, it’s a total body workout for your legs and abs, and works your heart and core unlike any other sport.

Stosur frames tennis as a comprehensive form of athletic conditioning rather than a narrow, skill-only game. By listing agility, speed, core strength, and stamina, she emphasizes the sport’s demand for coordinated whole-body movement sustained over time. The quote also highlights how tennis blends explosive actions (sprints, changes of direction, strokes) with endurance and cardiovascular load, making it both strength- and heart-training. Implicitly, it counters the misconception that tennis is primarily an “arm sport,” arguing instead that power and consistency come from the core and legs, and that the sport’s varied demands make it unusually complete as exercise.
