Effective cardiovascular exercises for fat loss include running, cycling, swimming, and high-intensity interval training (HIIT). These activities elevate heart rate and increase calorie expenditure. HIIT is especially popular for its efficiency, allowing for intense bursts of exercise followed by short recovery periods, which can elevate metabolism even after the workout is completed. Consistency in performing these exercises, coupled with an appropriate caloric deficit diet, can lead to more significant fat loss results over time.
