Interval training differs from steady-state cardio in that it alternates periods of high-intensity effort with lower-intensity recovery phases, promoting enhanced cardiovascular fitness and fat burning. Steady-state cardio involves maintaining a consistent, moderate level of exertion throughout the workout, such as jogging at the same speed. Interval training can lead to improved metabolic rate and increased calorie burn during and after exercise, making it an efficient workout option. Both training forms have their benefits, and combining them can enhance overall fitness and endurance levels.
