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?

What the Pros are saying...
My favorite thing about the Corefirst Trainer is that it keeps you connected. I constantly feel every muscle turning on all the time and get the most out of every movement.
I like how the Corefirst Trainer activates the muscles that are intended to be activated for each movement and how it acts as a personal trainer tapping you on the shoulder saying, “Hey, activate this.”
One of my favorite things about Corefirst is the ability to add resistance to the body without having to hold onto anything.
You can do everything you would ever want to do with HIIT, but you get to add more resistance without having to worry about holding on to different dumbbells, kettlebells or weights.
The Corefirst Trainer is one of the most versatile fitness tools I've ever used. For HIIT, it can be used as resistance, or for stability, and you can do a lot more with it than you can with other training tools.
