<human>:  Can you recommend a good fitness program for me to try?
<bot>: A great fitness program to try is High-Intensity Interval Training (HIIT). HIIT involves bursts of very intense exercise alternated with recovery periods of low-intensity exercise. This type of workout typically only takes about 30 minutes and has been known to be very effective for burning fat, improving aerobic and anaerobic capacity, and overall health.
