About Us

We believe the quality of our health determines the quality of our lives—and nothing is more important than that. We believe fitness is about strengthening and conditioning your body and mind so you can get out there, explore the world, seek new adventures and be the person you were meant to be.

Windy City Strength & Conditioning is a dedicated, full time Strength and Conditioning facility, and the home of Windy City CrossFit—the first CrossFit facility in Chicago. We use kettlebells, barbells, dumbbells, bumper plates, jump boxes, medicine balls, rowers, gymnastics rings, parallettes and pull-up bars to effectively train our athletes every day.

If you want to be healthy and happy, we want to help!

At Windy City SC, we believe getting fit should be FUN, varied, and done with friends. There is power in being part of a community of like-minded individuals that supports us, shares our experiences, and celebrates our successes. 

There’s no ‘one right way’ to training. Your goals are unique, which is why we offer a variety of program options. Whether you’re looking to just get fit, get strong, or fuel your competitive fire, we have a program for you. 

We listen to what you’re looking to achieve, then lay-out the best path to get there. No prior experience is required.

The Sierra Club Foundation

At Windy City, we believe in getting out there, experiencing the world, seeking new and exciting challenges...and using our health and fitness to be the people we were meant to be. We also believe in giving back, paying forward and being socially responsible.

We believe so strongly in this that we’ve partnered with Merchant Giving Project so that a portion of every credit card transaction will be donated to The Sierra Club Foundation, an organization dedicated to safeguarding our planet so future generations will have an “out there” left to explore.

Barbells for Boobs

Windy City started hosting an annual fundraising event in 2016 helping Barbells for Boobs, a non-profit organization that strongly believes that everyone has a right to know if they're living with breast cancer. Together, we've raised over $21,000 for the organization, which involves a team workout, raffles and prizes. Join us at our next event in December and help everyone who benefits from this organization.
