HIIT Me, Baby

1 comment
Day 2 of our post-holiday sweat sessions introduced me to a whole new cardio-concept: High Intensity Interval Training or HIIT.  Up to this point my cardio go-to has been a good moderate jog, using distance as my main benchmark. 3-5 miles: good day. 6.5-8 miles: great day. My concentration has been on building endurance and getting in shape. But realistically it's probably not the best way to train, at least, all the time. Lucky for me, Travis is continually researching different types and styles of exercise and I'm more than willing to play guinea pig. So...HIIT, as you might assume from the name, is an exercise style that intersperses periods of high intensity workout, such as sprints, with less strenuous activity such as a moderate jog. While Travis likes to fully understand the science behind the fitness, I usually go for the Wikipedia-style overview. Here are a couple of the key benefits that sold me on trying this new format: Wikipedia cites a study by Gibala et al. which "demonstrated 2.5 hours of sprint interval training produced similar biochemical muscle changes to 10.5 hours of endurance training." All I have to say to that is, "Yes please!" I seriously love the idea of being able to see the results of my workouts in a fraction of the time. Wikipedia also mentions a study by King suggesting HIIT increases resting metabolic heart-rate for 24 hours post-workout. Meaning: I can feel slightly less guilty about the occasional chocolate slip-ups. So, today we tried our first HIIT workout at the local track. It was a great opportunity to debut my new pink Nike AirMax running shoes....


They were super comfortable and cushion-y, (and hello, pink!) but the jury is still out on whether they will replace the Nike Lunar Eclipse as my favorite running shoe. All in all the workout was definitely tougher than I thought it would be...2 miles worth of intervals left me winded. And I fully anticipate needing a soothing massage sometime this weekend! But I'm intrigued by this new concept and it looks like we'll be making interval training a regular part of our 2012 exercise routine. What cardio works for you? Have you ever tried HIIT?
