The best exercise for losing weight is cardio, such as running or walking. High-intensity interval training (HIIT) is also a great way to burn calories quickly. You can do HIIT by alternating between short bursts of intense activity with periods of rest. Strength training is also important, as it helps build muscle which in turn burns more calories than fat.
