HIIT stands for High Intensity Interval Training and it really kicks your butt!!
What is it?:
It is a workout where you walk slow for 1-2 minutes and then sprint at your fullest potential for 30sec-1 min and then cool your body back down for another 2 min and then repeat the cycle.
What's the point?:
The point of HIIT is to shock your body and wake it up. When you sprint for those 30 sec to 1 min you are really pumping up your heart rate and then you cool it down for 2 min. When you do this, you are burning alot more fat vs. just running or walking the tread mill at a steady pace. It is a good and fast way to burn off that fat!!!
Low Resistance vs High Intesity:
Low resistance of aerobic exercise came about is a study that showed low-intensity exercise burns a greater percentage of calories from fat as opposed to carbs; however, when high-intensity exercise is practiced, the research showed the percentage of fuel from carbs is increased, while the amount of fat utilized is greater than or equal to that burned during low-intensity exercise. In research, HIIT has been shown to burn adipose tissue more effectively than low-intensity exercise—up to 50% more efficiently!3 In other words, HIIT speeds up your metabolism and keeps it revved up for some time after your workout. The bottom line is HIIT training burns a greater number of total calories than low-intensity training, and more calories burned equals more fat lost.
I also read that Beyonce does this as well to stay in shape:
Borges reveals the secret to achieving Beyoncé’s incredible physique is training with health in mind, as opposed to looks. “If you think about being as healthy as you possibly can, there is no way you’re not going to look like a million bucks. And that’s what Beyoncé did,” he tells In Touch. Their goal was to make sure she could run around for two hours onstage without feeling winded every night. So before the tour, Beyoncé, 28, did interval training — 45 minutes of alternating between sprinting and running on the treadmill, followed by body-resistance work. Now, Beyoncé does yoga and Pilates for an hour on show days and body-resistance exercises on days when she’s not performing. Borges also tells In Touch that the star eats a sensible 1,600-calorie diet of lean proteins with healthy carbs. “The truth is, it’s a lot of sacrifice. You have to push yourself,” Beyoncé has said. -www.theybf.com
I also did HIIT yesterday and man did it kick my ass. I did 20 min of it on the treadmill, where I walked for 2 min at 3.5mph and then I ran at 6.6mph for 1 min and continued that cylce for 20 min. I also did it on the bike as will. I went from 80mph for 2 min and then jolted up to 120 mph for 1 min. I am not a runner nor a biker, so those speeds were really challenging for me and I really got a great workout from it!
I advise everyone to at least try it, it is such a great workout!
