High Intensity Training, WHY ARE YOU STILL RUNNING FOR HOURS ON THE TREADMILL

High Intensity Training, there is no real need to run long distances anymore unless you are a distance runner.
Lets talk a little about how intensity affects the way your body reacts in regards to fat burning. Lipolysis (the burning of triglycerides, FAT)  gets affect by two key components.  When we do low intensity cardio or what is referred to as LSS (low intensity steady state) we only release noradrenaline.  This has a good long term metabolic effect on our bodies as it continues to illicit a fat burner response for approximately 24 hrs.  Now here is where it gets really good, when we do HIIT (high intensity interval training) our bodies not only release noradrenaline but they also release adrenaline!  This will increase our bodies need to consume oxygen post exercise which raises our metabolic rate for the next 24 hrs.  HIIT training also has a greater ability to increase VO2 Max which is essential for all competitive athletes.  In simplistic terms VO2 Max is the bodies ability to take in less oxygen and use it more efficiently over a shorter period of time.  The higher your VO2 Max the better you can perform for a sustained period of time.
For any non endurance athlete out there (football baseball tennis soccer etc) there are clear and irrefutable reasons to do HIIT training.

Here is the real fun part, HIIT DOESNT HAVE TO BE DONE ON A TREADMILL.  Thats right you can in fact take your HIIT training to the weight room to the park or where ever you want.
A good example of HIIT off the treadmill would be sets of lightweight squats for AMRAP (as many reps as possible) 30 secs, 30 secs rest, squat AMRAP 30 sec , rest.  Repeat this for 10 min and then let me know if your heart explodes.

Hill sprints and stadium stairs are all awesome ways to use HIIT training.  Sprint up a hill walk down take a couple deep breaths repeat.  Same with stadium stairs,  once your done, try not to puke.
