Ready to tear up Tuesday like, HIIT me with your best shot! Fire away. If you’re a real tough cookie (or a softy searching for those abs – no judgment), here’s the lowdown on a few of my favorite (and new) HIIT classes in Chicago (and elsewhere), including the new FlyFit class at Flywheel, Barry’s Bootcamp, Studio Three, Shred415 and Sweat Fitness. With so many classes, it’s hard to choose. I can’t pick a favorite, so I do them all and let you decide! Check out my recap of all things HIIT below.
