GET YOUR QUESTIONS ANSWERED about how to: evaluate your strength & mobility to determine your superpowers & your gaps, & include my methodology in your own training.

LEARN WHAT TO FOCUS ON VS. WHAT DOESN'T MATTER FOR YOU: determine what's holding YOU back & target it, instead of wasting time on endless drills.

DESIGNED FOR THE OVERWHELMED & TIME-CRUNCHED: instead of wasting precious energy on shit that doesn't work for you, use your limited time to its fullest. And jumpstart the process with information divided into 5 digestible modules.

Straight-Arm Inversions Are the Worst.

Ok, maybe not the WORST. But if you've made it here, they're probably keeping you up at night.

Do you feel...

  • frustrated that you have gotten this far in your training but still struggle with this "easy" skill?
  • like something is missing in your approach but you just can't figure out what that is?
  • that no matter how much you work on them, they never get any better?
  • embarrassed that you can't get something that others pick up so quickly? 
  • unsure how to do such as a complex skill, much less how to coach it?

Oooof, I get it. I used to be there too. If you said yes to any of the above, then this course is for you.

This course is not for absolute beginners. It's for aerialists who have worked at least some on straight-arm inversions but cannot get them to click, feel effortless, or be pain-free. There are no prerequisites besides a solid two-arm hang from any apparatus & the ability to get upside down on it (even if it's not always pretty).



When I started training aerial over a decade ago, it was wild. Most of the knowledge we have today either didn’t exist or wasn’t easily accessible.

If your coach said "do a thing," you either trusted them blindly & did it... or you didn’t do aerial. Because those were your choices.

No one was there to tell me what was safe for my shoulders or how to gain overhead mobility. And surprise, surprise... I got injured. Badly. The doctors weren't exactly sure what was causing my pain, but I couldn't raise my left arm over my head & my shoulder would sublux in my sleep.

The amazing part is that I found a TEAM of movement professionals who I relied on as a sounding board as I self-rehabbed my shoulder. I radically altered my approach & learned everything I could about human movement. I became a Gyrotonic trainer. I studied nutrition. I got various movement certifications. I went ALL the fuck in. And it worked.

TODAY, YOU ARE SO LUCKY! You don’t have to be a pioneer. There is so much information ready for the taking. And, listen, I know you don't have time to waste.

Speaking of ready, I'm ready to share the things I have learned about biomechanics, mobility, strength training, & more so that you can skip a lot of the pain that I went through.

You don't have to continue to struggle not knowing if what you're doing is "right" or right for your body!


Here's How It Works:

  • You get 3 hours of video instruction on straight-arm inverts divided into 5 MODULES.
  • Each module is divided into 5-10 minute lessons that tackle different aspects of the motion that you can then TRY OUT on your own body.
  • In each lesson, you will have the ability to ASK QUESTIONS so you can be sure you're doing what's best for your body.
  • If you tag me in your Instagram videos, I'll give you PERSONALIZED FEEDBACK to help you progress more quickly.
  • My goal for you is to UNDERSTAND what's not working & why, so that you can target the hell out of it in your training & GET RESULTS.
  • You will have lifetime access to the recordings, which you can use to REVIEW & PROGRESS your technique.

Hi, I'm your coach, Jessica John👋🏻

I'm the founder of Circus Mobility. I stumbled upon circus as an adult, & I was hooked from my first aerial silks class. At that time, I was a leadership analyst at the CIA with a weird hobby. Slowly but surely I allowed that weird hobby to take over my life. I became an aerialist & eventually a master coach to aerial & pole performers & teachers all over the globe.

My coaching philosophy is evidence-based & multidisciplinary, addressing technical, strength, mobility, nutrition, mindset, & creative challenges as they arise. I use sport & exercise psychology theoretical frameworks to design performance programs that help my clients achieve their goals through habit-based change. My practice is applied & practical, aimed at helping driven aerialists reach their highest potential.

You're here because you want more options. You're sick of feeling run-down, beat up, & like you're just treading water with your skills.

You know that you need to do something different. Well, you're in the right place. You're my people.

Frequently Asked Questions


Who is Inversion Conversion: The Course for exactly?

It is for aerialists at all levels struggling with straight-arm inverts. The inversion is a foundational aerial movement that has different strength & mobility demands depending on the individual. It is not for the beginner beginner. The course assume that you have comfort from hanging from 2 arms & that you can get upside down with a bent-arm inversion even if it's not always pretty.

What if I am more advanced? Will I still benefit from this?

You definitely will! You will come away with tidbits you might not have even realized were happening in your body. If you're a coach, you'll come away with better ways to coach the skill & evaluate progressions on different bodies.

How long are the trainings? I'm super short on time?

I totally get it! Each lesson is only 5-10 minutes long. I'm going to give you what you need to move forward without overwhelming you with unnecessary extras.

Is this course live?

No. This course was recorded live in 2022. But this is the recorded version. You will have the advantage of going through the materials on your own time.
