Fierce45® – A Fierce But Amazing Workout!

Fierce45®, a High-Intensity Pilates full-body workout, is now open in Littleton! Their newest location, at 2100 W. Littleton Blvd sits next to Bacon Social.  Fierce45 offers small group fitness classes on one-of-a-kind resistance machines, The FierceFormer™.  This studio and these classes are like nothing you’ve ever experienced. It’s a calorie blaster (500-800 per class) of exercises combined with the fundamentals of alignment, breath and mindful movement, with no stress to your joints or spine. You will sweat, your muscles will tremble and you will experience the Fierce45® difference.

Fierce45 incorporates slow, controlled, continuous tension, quick transitions and effective range of motion to burn through slow and fast twitch muscle fibers, alike. You will work your entire body in just 45-minutes. Each class combines strength, endurance, cardio, balance, and flexibility exercises on our custom FierceFormer™ resistance machines. The goal is to keep you in the fat burning zone for the entire duration of the class to build long, lean muscles.

Your first THREE classes are complimentary and Childcare is provided for a small fee.  Give Fierce45® a chance to show you how strong your body is and how quickly you can see physical results!   To book classes, visit  or call (720) 324-8777
