About Us

At A3 CrossFit in Grayslake, our coaches put our experience to work for YOU in achieving your fitness goals and get you real results! Whether you come looking to feel better, improve your heath, or break though to the next level, our community of passionate experts can’t wait for you to try us out to see why we are different from other gyms.  It may not be the easiest thing you have ever done, but it certainly will be one of the most rewarding.

We serve Grayslake, Round Lake/Hainesville, Libertyville, Gurnee, and anywhere else in the greater Lake County Area

We offer small group classes led by trainers who will motivate you, along with the other athletes, to perform at your best.  Each class is designed to challenge you physically and mentally.  We strive to bring elite fitness to all individuals, regardless of their current fitness level.  Beware, we are not a globo-gym!  We have no ellipticals, no smoothie bar, no mirrors, and no excuses!  Just an intense workout designed to suit each individual's needs.  It's not easy.  You will leave each session feeling exhilarated and exhausted at the same time.

So what are you waiting for? It's time to expect more from your workout!
