About Us
At A3 CrossFit in Grayslake, our coaches put our experience to work for YOU in achieving your fitness goals! Whether you come looking to feel better, improve your heath, and break though to the next level then our community of passionate experts can’t wait for you to try us out for a FREE WEEK of training. 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

Our gym is a community; a family that sweats and suffers, laughs with and supports each other. We are not your standard gym; and we take pride in that. Everyone has given us the highest honor in trusting us with their fitness, and no one has been disappointed. We look forward to adding you to our family.

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 daily 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!
