• It's frustrating when all your hard work doesn't result in more new members.

• You don't know why you can't keep people coming back.


• It shouldn't be so difficult and frustrating to get people to realize how much they need your classes.


• How to create class experiences people crave shouldn't be such a mystery. 

• The disenchantment you feel can make wonder if it's worth it to keep trying.

Consistently attract your dream clients.

It shouldn’t be so hard to get people to see the value of what you offer, but the truth is that most fitness businesses go about marketing themselves the wrong way.


We'll teach you how to avoid common problems that cause fitness professionals to struggle, stress, and burnout.


We'll show you how to reveal your unique value and position yourself as the ideal solution for your dream clients that get them excited to sign up and that you feel excited to talk about.

Confidently sell out your classes.

Teaching a group fitness class is an art and a science. It's about creating an unforgettable experience for the participants. To do this effortlessly, you need to go beyond just teaching a great workout with a high-energy playlist. The equipment or the studio's appearance doesn't matter.


We'll teach you what your certification doesn't cover... HOW to create experiences that people prioritize above everything else that competes for their time and attention.

Your passion for fitness only takes you so far.


You're here because you've realized that being passionate about fitness is different from consistently selling out your classes.


Unpredictable class numbers, unreliable income, and not knowing what to do can make you feel disillusioned about being in the industry.


We know how it feels when you know there must be a missing piece that will unlock the secret to being sought after and making a change.

We found out what it is. There is an art and science to attracting your dream clients and creating immersive experiences that they make time for. Our decades of experience coaching and consulting for fitness studios worldwide have shown us one thing- it works. And now we want to teach it to you.

Spoiler alert: a good workout and a good playlist is not enough...


We will show you how to position yourself as the perfect solution for your dream clients so they feel excited to sign up for your classes.


We'll also teach you the art and science behind creating fun, immersive, and addictive class experiences that keep them coming back.

You CAN sell-out classes and know that people value what you bring to their lives.


Your journey to Fitness Career Mastery begins here.


Your business’s success demands you nail the two elements of an unforgettable experience:

1/ Attract YOUR people.

2/ Take their breath away.

First, attract YOUR people.

Attracting the right people comes down to ensuring you are properly positioning your value to your dream clients. If you're struggling to get new clients, this is most likely the reason why.


Doing this well goes beyond informing them of what kind of workout you offer and your schedule. Why should your dream client come to YOUR studio? How is coming to your classes going to improve how they experience their life?

Marketing WHAT you do does nothing to answer these questions and distinguish you from everyone else that does what you do.


You have a unique perspective. An outlook on life that is yours alone because it has been shaped by your experiences and taste, and is reflected in the experience you provide.

Our job is to draw it out of you and use it as the bedrock to communicate the mountain of value that you provide- so you begin to attract more clients in.

We help you authentically express your unique value to your dream clients so you can attract the people you're meant to serve and stand out from the competition.

Second, Take Their Breath Away.

The keys to packed classes, member retention, outstanding client referrals, and five-star reviews can be found in the quality of the experience you provide for your clients. 


Over decades of training more than 1000 instructors in over 13 countries in multiple languages, we’ve discovered what it is that the most influential instructors in the world do, and have distilled this down into a science-backed formula that YOU can use to create unforgettable, immersive, and addicting workout experiences for your clients - no matter where or what you teach.

We teach you the skills you need to know in order to transform your workouts into meaningful experiences your clients can't live without.

Shaun knew he was getting amazing results for his clients. They would come in crippled and hurt and walk out with a strong, functional body. The problem was he didn’t know how to express or communicate the value he provided to these people’s lives and therefore had a hard time justifying higher prices. After working with FCM he finally gained the confidence to raise his prices and is now at capacity. Learning how to differentiate his training method and put concrete messaging around the value his clients received made all the difference in the success and growth of his business.

Nothing feels better than consistently sold out classes.
