<human>:  What is the best type of exercise for weight loss?
<bot>: The best type of exercise for weight loss is high intensity interval training (HIIT). HIIT involves alternating short bursts of intense exercise with brief periods of rest or lower intensity activity. This type of exercise has been found to be more effective than steady-state cardio for weight loss, as it boosts your metabolism and helps you burn more calories in a shorter amount of time.
