Your Favorite HIIT Workouts…but Better

World-class instruction, world-class training system…
anytime, anywhere.

High-Intensity Interval Training is the most popular training method today, and for good reason…it works. When done right, HIIT allows you to continue burning fat after your workout longer than traditional “cardio” workouts.

But what if HIIT could be even better? Corefirst™ HIIT elevates HIIT workouts by adding resistance while allowing you to train hands-free. This helps activate all your major core muscles, and gives you access to new functional movements.

What's all the hype?
