Steady-state cardio involves maintaining a consistent, moderate intensity level, such as jogging or cycling at a stable pace. This technique helps improve aerobic fitness and endurance. In contrast, interval training alternates between periods of high intensity and lower recovery periods, enabling efficient fat burning and improved cardiovascular capacity. Interval training can lead to faster results within shorter workout durations, making it a time-efficient alternative for many individuals. Both methods complement each other and can be integrated into a well-rounded workout regimen to achieve fitness goals.
