Voted Best Pilates Studio in Chicago

–CitySearch Chicago

Welcome to Flex, where Pilates isn’t just a way to make your friends crazy jealous of your svelte figure and your rock hard abs (although that is a pretty nice perk).
Flex Pilates is a lifestyle.


It’s what you wake up for at 6AM. It’s why you leave work early. It’s what you talk to your friends about, because they can’t stop gawking over how amazing you look. Not to mention how you feel.


Flex is much more than a studio. It’s the reason the rest of your life suddenly ‘fell into place’ and it’s the reason why you go to class at Flex.
Every. Damn. Day.


Bootcamp is the best and fastest way to dive right into pilates. Never done it before? That’s OK. After a month that all changes, along with your body.

Reformer Group Classes

Classes for up to 11 people with an instructor who makes sure your posture is perfect and your muscles are shaking.

Private Classes

Welcome you to your private pilates studio. Spend an hour getting intimate with our Allegro 2 reformer as our instructors guide you through each move.

Prenatal Classes

For all stages of pregnancy and for new moms who want to get back into shape, pilates offers the perfect balance between mind and body. If you want to schedule a private prenatal session or duet email us at
