WE WROTE THE BOOK on amazing transformations
Now we’re giving you THE FORMULA.
For years, The 12-Week Body Challenge has been the go-to program for transforming bodies and building unstoppable confidence. This Spring we are taking everything that makes it effective and adding fat-blasting strength training strategies. This NEW fitness-focused nutrition program is packaged into a powerful 8-week nutrition program that will deliver results on the scale and in the mirror.
The Body Challenge has been redefined – just like your abs, arms, and legs can be if you commit to the plan.
INTRODUCING: The 8-Week Fitness Formula.
The 8-Week Fitness Formula is a streamlined, no-BS version of our signature 12-Week Body Challenge—focusing on fat loss, strength building, and real accountability to get you in the best shape before summer.
The Fitness Formula kicks off Monday, April 14, 2025.

That’s what 8 weeks of consistency can do. No gimmicks, no fads—just a plan that works.

HOW DOES IT WORK?

TEAM IRIS VS. TEAM JULIE
Our expert trainers (and veteran bikini and physique competitors) are going head-to-head to lead their team to victory.
They’ll keep you accountable and give you their expert tips and strategies to elevate your results.
Join them in-person for a workout, or catch them live inside the private team page each week.

SIMPLE WEEKLY MEAL PLANS
As the saying goes, you can’t out-lift your fork.
But you also can’t build muscle if you’re living off of celery sticks.
Each week we give you an easy to follow meal plan designed to fire up your metabolism and fuel your muscles.
The plan is simple. No guesswork.

BURN FAT & TONE MUSCLES

The Fitness Formula gives you a weekly target for workouts as well as tips and tools to get the most out of your strength training.
Blast fat. Sculpt a toned body you can feel confident in.
Plus, compete for weekly prizes and grand prizes – including best before and after, testimonial, and more! It’s not just about what you can accomplish on the scale, but off of it that matters!
Ready to go?! This is your chance to level up, without the overwhelm. Join now and make it happen.
If you’ve been waiting for a sign—this is it.
Stop putting yourself last. Let’s do this together.

Body Challenge FAQs
How much weight will I lose?
This depends of course. On average, weight loss ranges from 15-35+lbs. Some might join us for the last 5-10, some might join us to maintain their lost weight. We are here to help you with whatever weight loss goal you have.
When is kickoff? What if I miss kickoff?
The 8-Week Fitness Formula begins on Monday, April 14, 2025 with a virtual kick-off inside the price challenge group.
Do I have to workout at The Fitness Asylum to join?
No, you do not have to be a member of our gym to join.
If you are looking for a supportive community to enjoy dynamic workouts with upbeat, expert trainers, we do offer the complete Fitness Formula experience for just $297, which includes eight weeks of unlimited workouts.
Do you use any special food journals or software?
We host our program on an online platform that is free and easy to access on your phone, laptop, or desktop computer. We also provide online tutortials to reference to get up-to-speed. We know technology isn’t everyone’s strong point!
We also recommend optional online tools that are free, but none are required.
What if I am going on vacation during the program?
Missing time for a vacation, or business trip always happens, so no worries at all.
Life happens, and you are learning how to plan for success in this program. People travel, attend weddings, celebrate milestones, and so much more on this program. Your goals don’t have to take a backseat to your social life!
Is it normal to be afraid to sign up? (asking for a friend)
Very. We understand embarking on something new (or trying to lose weight again) is intimidating. We all fear failure and that is why our program is just as much on creating habits and establishing the right mindset as it is on the food.
The people who are successful with our program are not better than you, or smarter than you or luckier than you—all they did was take a deep breath- sign up and follow along.
We know you might be nervous but you are not alone. There will be many people ready to work right alongside you to help you be successful.
Can I do this program if I don't live in MA?
Absolutely! In fact, we have dozens of participants each season who live in other parts of the United States. From California to Florida to Maine – you can do this program from anywhere!
IS THere an age requirement?
You must be at least 18 years old to participate in our nutrition programs.
WISHING FOR IT WON’T GET YOU RESULTS.
Here’s the truth: Results don’t just happen.
You can read about workouts, scroll fitness tips, and wish for a flatter stomach all day—but if you’re not actually showing up, nothing is going to change. This program works because YOU will work.
