Farrell's eXtreme Bodyshaping

Burn Fat. Build Muscle. Boost Confidence.

Are You Ready to Transform? Join the premier Denver 10-Week Fitness Challenge as you add muscle, lose fat and transform your body and the way you think about fitness.

At Farrell's eXtreme Bodyshaping, we offer Boot Camp style classes that are designed to give all fitness levels extreme results. We offer a 10-week challenge that includes the following four components. These components will help you transform your body and change the way that you think about fitness and nutrition. We will help you make long-lasting changes to your lifestyle. Here are the four components of our program:

Kickboxing classes

Our kickboxing classes, derived from martial arts, are high-intensity cardio classes that burn fat and build endurance while offering variety and fun.

Strength Training

Strength training is essential to building lean muscle and burning fat and calories – in motion and at rest. Using resistance bands provides the benefits of building core strength in a safe environment.

Nutrition Coaching

We provide resources and information to fuel your body for peak performance on and off the mats. From carbohydrate and protein intake based on your body measurements, to simple meal plans, healthy eating is essential to your success.


Our certified instructors are trained to keep you safe, motivated and working hard in each class to help you reach your Level 10. Instructors add variety and fun to class while encouraging you to strive for excellence.

Our coaches provide one-on-one support. They encourage, motivate, answer questions, and help guide you through the program.

Whether you are out of shape and need to lose weight, an active athlete looking to boost performance, or have never stepped foot into a gym before, our 10-week fitness challenge can help you meet your goals.

FXB Members Summit 14,265 ft. Mt. Quandry

I love how FXB creates an instant bond between people who meet for the first time, and it was the same for this hike.

What is a FIT Member?

The transformation of our members doesn’t end after ten weeks. In fact, our members are encouraged to join our Farrell’s Infinite Transformation® (FIT) program, which offers additional FIT challenges and plenty of fun.

What is Farrell's eXtreme Bodyshaping Anyway?

So what is so eXtreme about Farrell's? The eXtreme does not describe the eXtreme nature or difficulty of our classes, as they are designed for all fitness levels. But rather the eXtreme results that our members achieve.*

Goodbye "B"...FXB Will Miss You!

"I still remember talking to Bidyut the very first day he came to the gym," recalls Dan Dorenkamp, FXB Denver owner.

Three Years Strong at Farrell’s

I am three years strong. That’s three years of committing to a healthier, happier me. Three years of choosing to live longer and stronger for those around me. In June of 2015, I chose to live healthier for someone else, my unborn child.

My Farrell’s Transformation is Part of My Life!

Many of my friends and family are experiencing health-related issues as we age. I lost my younger brother recently to a health-related illness. I was not content to accept that fate and decided that I needed to make a change in my life. I enrolled at Farrell's.
