What would you say if I told you there is a proven way to prevent dementia, improve cardiovascular health, build muscle, and reduce the risk of almost all chronic diseases? Would you be interested? Would you believe me if I told you it costs nothing and only requires about 45 minutes of work per week?

Admittedly, that first paragraph sounds a bit like an infomercial…However, recent scientific studies support the widespread benefits of High Intensity Interval Training. If it sounds too “Intense” for you, don’t worry. This type of exercise is not reserved only for the super fit. So let’s define what it is and put your concerns to rest.

97356936What is High Intensity Interval Training (HIIT)?

Just what it sounds like. The idea is to perform an exercise at a high level of intensity for short bursts of time, combined with longer periods of low to moderate intensity “breaks” in between. The concept is simple and can be applied to a variety of exercises including:

  • Running (treadmill or outside)
  • Elliptical
  • Bike
  • Row machine
  • Stair climber (or actual stairs)

These are just a few suggestions, but you could use this type of training with basically any exercise you want.   You don’t even need machines.

Getting Started

It is important to note that you may have some limitations concerning what type of interval training you can do based on current or past health issues. You should always consult with your physician prior to starting any program to ensure your heart is healthy enough to engage in high intensity exercise.

How do I do it?

Like any exercise, you will want to start with a warm up.

  • Begin with 3 minutes of a low intensity warm up.
  • After your warm up 30 seconds of intense exercise. Intensity should be high enough that you couldn’t do another second!
  • After your intense exercise keep moving but slowdown for 90 seconds catch your breath and let your muscles get ready for the next 30 second burst.
  • Repeat 7 more times for a total of eight intervals.
  • After your last interval, spend 3 minutes cooling down at a low intensity.

From beginning to end this workout takes 22 minutes, and 6 of those are warming up and cooling down. Really just 16 minutes of work…and you are done! To maximize your results do this type of workout 3 times per week.

What are the Benefits?

Here’s the best part. The benefits of this type of exercise are dramatic. Here’s the list of what High Intensity Interval Training has been shown to do (read the whole list!):

  • Increased insulin sensitivity (Helping to fight diabetes)
  • Better breakdown of stored fats (Helping to fight your waist line)
