HIIT kicks even more ass

I love HIIT workouts.

  • Short duration
  • High intensity
  • Increased fat loss thanks to EPOC
  • Improved anaerobic endurance
  • Improved muscular power
  • Improved athletic performance
  • Honorary BADASS certification

And if that wasn’t enough, it also turns out that HIIT is good for your overall health.

HIIT - before and after - fat to fit


Here’s the latest scientific proof.

Researchers at the University of Glasgow took 10 overweight/obese men and subjected them to three different fitness protocols:

  1. Sitting on their ass…aka the couch potato workout
  2. 4 x 30 second full-intensity sprints with 4.5 minute rest periods (HIIT workout)
  3. A single full-intensity sprint (ES – Extended Sprint workout) designed to be equal to the work done during the HIIT workout.

The day after doing these workouts, the participants…

  • had a fasting blood sample taken,
  • undertook an oral glucose tolerance test to determine insulin sensitivity index (ISI),
  • and had blood pressure measured.

Here’s what they found….

  • Total work performed did not differ between the HIIT & ES workouts
  • More power was generated during the HIIT workouts than during the ES workouts
  • Both the HIIT & ES workouts resulted in increased Insulin Sensitivity compared to the control group
  • The HIIT group saw a 63% increase in fat oxidation compared to the control group
  • The ES group saw a 38% increase in fat oxidation compared to the control group

And just in case you weren’t aware, increased insulin sensitivity & fat oxidation is exactly what our obese / diabetic society is in dire need of.

And this was after just one workout…imagine how much better things will look after 52 weeks of High Intensity workouts.
