How does the frequency and intensity of cardiovascular exercise affect fat loss and fitness levels?

The frequency and intensity of cardiovascular exercise affect fat loss and fitness levels by influencing calorie expenditure and metabolic rate. Higher intensity cardio, such as interval training, burns more calories and improves cardiovascular fitness in shorter sessions. Increasing the frequency of cardio workouts, combined with varying intensities, helps boost overall fat loss and enhances cardiovascular endurance, leading to better fitness results.
