Different types of cardio impact weight loss variably, depending on intensity and duration. High-intensity interval training (HIIT), for instance, engages in short bursts of intense activity followed by rest periods, boosting metabolism and promoting fat loss even after exercise. Steady-state cardio, like jogging or cycling at a consistent pace, is effective for burning calories during the activity. Both methods can be beneficial, but incorporating a mix promotes well-rounded fitness and prevents adaptation. Ultimately, the best cardio for weight loss combines enjoyment and consistency for sustainable results.
