Whether you work from home, don't feel comfortable in the gym or have a job that just makes physical exercise spaces a challenge, FLEX is for you.

Welcome to the community ditching the gym for endorphin highs, kickass music and endlessly motivating workouts.

Radically entertaining HIIT workouts and more: introducing Flex. From now on, all you have to worry about is what will happen if you binge exercise like you do your favourite TV show. Flex is a revolutionary new way to work out pulling in a new community of members from Crossfit, Orange Theory, and F45.

With Flex, you can take an audio or video class and our platform will read your heart rate, count every separate rep and show you how you stack up against the community and your personal record on our real-time leaderboard.

With all this data, we create a wildly different workout experience. We make working out not only not suck, but awesomely fun.

Whether you get involved in a live class or jump in the running of the weekly competition, know that as soon as you hit start - you’ll end the class having laughed and worked harder than you thought possible.

Say goodbye to thinking about exercise. Jump in a class and it will just happen.

Named the “Future of fitness" by Shape Magazine, Flex gives you a game-changing workout, no matter your fitness goals.

“Not even my NAVY seal coach got me these numbers in one sitting”

“Yeah, so this is my new favourite thing. I thought I would just try one class out on Monday, now it's Friday and I've taken five.”

“Flex is genuinely the best investment in my emotional, mental and physical health I have ever made. I compete in the competitions with our budding community and every day that I take a class is a happier day because of it.

“Literally all I have to do is start a class. If I can start a class I know I’ll forget I’m working out and will end the hour in a pool of sweat, a smile on my face and feel awesome”

“I love the fact that I can get a class at home and feel like I’m part of something bigger.”

“Motivation is almost never an issue for me. Now, I have it all at my fingertips...I continue to be amazed at what I learned during the session.”


The FLEX app is free to download and use with a one-month free trial and then a $9.99/month or $19.99/month subscription, which is a ridiculous deal if you think about it - replacing one studio class with unlimited Flexing.

Unless canceled 24-hours before the end of subscription term or trial, you will be billed automatically at a rate based on your chosen subscription plan at the end of the free trial or on your renewal date. Refunds will not be provided for any unused portion of your term.

Flex works!

I got the free trial and I am hooked. I love the themed classes, the coaches inspire me to try harder every time. Exactly what I needed.

I'm trying strength routines I previously would have thought were completely out of my comfort zone. I wish I could set weekly goals though and bookmark workouts I like instead of scrolling through.

Amazing interactive & emmersive experience

This app has amazing music, a leaderboard where I can see my results and results against others working out and so far it’s been really fun. It works with my Apple Watch which is sweet. Just referred a couple friends so we can work out against each other hopefully.

Fun Way to Get Your Sweat On!

I work remotely and doing these workouts keeps me from sitting all day! I told myself I would do those Pinterest workouts but that doesn’t happen. Sweat Flex does though! Def recommendations can’t wait to see more videos!
