YO! You found us! Julian and Austin here!


We hope you’re ready, because to join this program, get ready to move F.A.S.T.

We’re going to give you what we think are the basics to understanding what strength you have, mentally and physically.

When we say F.A.S.T., we mean it.

- FLEXIBILITY - You will have your mind and body stretched to it’s capacity. You’ll really feel muscles you may never noticed were usable.
- ABS & CORE. IS. EVERYTHING. Nuff’ said. You’ll see.
- STRENGTH - You’re probably thinking “Strong like bull!” Big muscles and chiseled body. Well, you’re right, but we want you to focus on your mental strength, too.
- TECHNIQUE - The most important thing to know above everything else, the “How”.

Once the initial program is donzo you’ll be ready to move on to our next addition to the KNOW YOUR MOVEMENT Program and trust us, you’re going to want to see what that’s about!

The app includes some super cool features that you'll love!
-Awesome F.A.S.T. workouts for anytime and anywhere
-Exclusive A&J videos that you will only see here
-Fun challenge days that will push you outside your comfort zone, both mentally and physically

No way of seeing what I’d be signing up for.

I get that this is a subscription app but my fitness level isn’t near theirs so it would be nice to have a free 7 day trial or even just a general layout of the app before having to put money down.
