<human>:  What is the most efficient way to exercise to burn fat?
<bot>: The most efficient way to exercise to burn fat is to combine short bursts of intense interval exercise with a regular moderate-level cardiovascular workout. Interval training, which alternates between intense bursts of activity and fixed periods of less-intense activity, has been shown to be more efficient in burning fat than exercising at a constant pace. Additionally, to maximize fat burning, incorporate both strength training and cardio into your exercise routine.
