Maybe you've heard of High-Intensity Interval Training (HIIT) and were immediately intrigued. And maybe you learned about HIIT and decided to head immediately in the opposite direction. Both reactions are completely valid, because anything with "high intensity" is bound to sound intimidating. Even to my most hardcore personal training clients (and to me), HIIT classes scream "beware." But enthusiastic or not, if you're at all interested in taking a HIIT class at your local gym, you probably have some questions.
For both the pros and the uninitiated, HIIT can seem endlessly intimidating. HIIT classes involve high-intensity bursts of work with only short rest periods in between, so going to a HIIT class is an exercise in extreme energy expenditure. These classes are often so tough that they may be shorter than other classes your gym offers. But as intimidating as it can be to go take a class where you'll be pushing yourself to your physical limits, more and more people across the country are choosing HIIT as their preferred mode of exercise.
According to trend data from Yelp 15, HIIT was almost never mentioned in Yelp reviews until 2011. The dominance of the exercise method has only increased since then, with HIIT mentions occurring three times more in 2019 than in 2015. This trend has both accompanied and been caused by a rise in HIIT classes being offered across the country.
If you want to find out for yourself what the trend is all about, here are a few things you might want to know before you go.
