Fierce45 stands out among other workouts for several reasons. Firstly, it provides a full-body workout that targets multiple muscle groups. The tangible and visible results I experience make it a standout choice. It easily fits into my hectic schedule with the quick 45-minute sessions. The instructors contribute significantly to the experience, offering expertise and motivation. Lastly, the consistent challenge – it is hard every time!

Fierce reminds me of what I love the best about weight lifting, yoga, and physical therapy – and yet it is totally unique. The results of FIerce are undeniable. I used to lose weeks at a time staring at the ceiling after lower back reinjuries. Now I can do my favorite things safely and more often than I could before.

I’ve taken a little over 200 classes at Fierce now and I can honestly say that it has not only transformed my body but my mentality and confidence as a woman. The community of Badass coaches and members keeps me coming back each week- the obliques are just an added bonus!
