High-energy workouts are primarily designed to be cardio-intensive.
Finally, these types of workouts are cardio-dominant. Most associate cardiowith a treadmill or an elliptical, but the term just refers to your heart. That’s why these workouts were originally called aerobics. Aerobic exercise utilizes oxygen to generate fuel, and that oxygen is pumped to your muscles by the heart. Therefore, aerobics are different styles of cardio exercises that keep your heart pumping and lungs breathing hard. They incorporate weights, bodyweight movements, plyometrics, machines, and even dance—but they do so in a way that you’re always moving and rarely resting.
