Overview of On The Fly

New for 2024, On the Fly Productions offers Elevated Fitness Classes that give people with ZERO experience an opportunity to train like an aerialist!  Their fitness classes are so much fun to attend – you don’t even realize you are working out!  Taught by actual aerialists, not only will you have incredible instruction but you might catch a glimpse of their high flying talent!  On The Fly was originally created for aerial professionals and kids, and they are thrilled to now offer Adult Fitness Classes. Co-owner, Jennifer Ragan, said “Why should kids have all the fun?” – I couldn’t agree more!

  • Start off your workout with a cardio and stretching warmup
  • Then rotate through strengthen & tone your muscles with various exercises using aerial silks, resistance bands and your own body weight.
  • After your rotations, it’s time for bungee fitness – strap your harness on and FLY!  The bungee portion of the class offers both great cardio and toning; the instructors will give you freedom to try various techniques from flying pushups, star jumps, runs, leap & lunge and more.

Final Thoughts 

I went into On The Fly a bit nervous, but I came out feeling great – my muscles were challenged and most importantly, I had fun!  On my second visit, I brought a few friends along and it was great to experience something new together.  I’m not sure that I’m meant to be an aerialist, but training like one is super fun and a great way to add variety to my fitness routine. They are definitely worth checking out!
