Lubbock, TX — If you’re looking for a really good workout to get your heart pumping and strengthen your legs, arms and your core, you can’t do much better than tennis. That’s according to a study by scientists at Harvard, who call it one of the “most perfect workouts”. They found that because tennis matches incorporate a lot of bursts of energy coupled with moments of rest, it’s considered an “HIIT”, or “high-intensity interval training.” Tennis and other racquet sports boost cardiovascular health because you engage your core, upper and lower-body muscle groups. A tennis match also burns twice the amount of energy you would during your nightly brisk quarantine stroll. A separate Australian study found that tennis also contributes to better aerobic capacity, lower resting heart rate and blood pressure, enhanced metabolic function, increased bone density and lower body fat.
