Quick Update- Instructor shout outs to Kaycee, Lana, Sonni and Erin who have taught some of my recent favorite classes in addition to Aga ofc! 10/10 (even though there are only 5 stars!) I’ve tried other reformer Pilates classes in STL and out of town, and Laforme is by far my favorite studio. It’s welcoming, upbeat, and filled with positive energy. All of the instructors (Aga shout out) and owner, Erin,—are charismatic and encouraging, creating a fun environment with workouts that challenge you but can be modified to your level. I joined as a member to complement my other workouts (spin, HIIT, lifting, boot camps), and this studio truly stands out. It’s unlike any other gym—highly recommend!

La Forme Pilates in St. Louis might just be my new obsession. I walked in as a total beginner thinking, “How hard could this be?” and… let’s just say my muscles had some thoughts the next day. 😅 But here’s the thing — every single class made me feel stronger, more confident, and a little less like a baby giraffe on the reformer. The instructors are super encouraging without being intimidating, and they somehow know when to push you and when to let you breathe (thank goodness). Yes, I was sore. Yes, I questioned my life choices. And yes — I kept going back because it’s THAT good. If you’re just starting out and want a workout that kicks your butt while also making you feel fancy and put-together, La Forme is it. 🙌
