At AAY! many of our workouts are considered HIIT, or high-intensity interval training. HIIT workouts consist of bursts of very intense exercise followed by short recovery periods.
> During the high-intensity intervals, as your heart rate goes up, your body's need for oxygen increases.
> During the short recovery, your body attempts to take in more oxygen and this cycle leads to an after-burn effect known as excess post-exercise oxygen consumption (EPOC). The greater the EPOC, the more calories you'll burn during AND after the workout.
Work intervals are purposely short (20-90 seconds) so that you can push yourself to the max every set. Studies show that it's when you work your hardest that you see the greatest gains.
> Rest periods are essential because they enable you to truly perform at your max in the next high-intensity spurt.
> Forcing your body to repeatedly acclimate between two very different states provides excellent conditioning.
To get the full benefit of your HIIT workout, you must put full effort into each work interval, and allow your body to recover during the rest interval.
> Of course, “high intensity” means “high intensity for YOU”. If you’re a beginner, a power walk may be YOUR high intensity. You'll still receive the same benefit if you're putting your full effort into each interval.
