Blaze Fit Reviews


Loving these workouts! They are a great way to sweat and still have time to accomplish everything on my to do list. After debating joining a gym or online program, I'm really pleased that I found this.

Another great workout! I really loved this total body workout. I am sweaty and burning in all the right places. I wish I could give this 10 stars.

I did it! It was great. Very hard, but I finished it! Can't wait to do the next ones.

Why Group HIIT Workouts?

Fast, Effective Workouts

Research shows that HIIT burns more subcutaneous fat than low-intensity cardio training such as jogging. With Group HIT Workouts, you'll reach your VO2 Max heart rate zone to burn calories and fat. Additionally, high-intensity interval training has been shown to yield higher excess post-exercise oxygen consumption (EPOC), which means you'll still be burning calories long after your workout has ended.
