HIIT, also known as high intensity interval training is a great technique to incorporate to maximize fat loss.  It is also very efficient.  Simply put, interval training is a period of near maximum output followed by a rest.  Outdoor sprints are a great way to incorporate HIIT into your routine.  
 
One of the most effective fat loss techniques I like to implement is sprints.  Short 40-50 yard bursts will turn your body into a fat burning furnace.  I have also included some compound bodyweight exercises to make this a hard-hitting, efficient circuit workout, perfect to do at the local high school track.  My clients and I  have seen great results from this routine, and I hope you do too.
