CROSSFIT: FUNCTIONAL FITNESS AT ITS FINEST

CrossFit is all about teaching the body to move efficiently and safely, then using this good movement under load and at velocity to create fitness. Each day the workout will train or test a different part of your functional strength or conditioning, not specializing in one particular thing, but rather with the goal of building a body that’s capable of practically anything and everything. CrossFit can be for everyone as movements can be scaled.

Train with us and you’ll also experience the difference great programming can make! This is at the heart of what we do. Workouts are not random and thrown together last minute, but rather thought out and planned over days, weeks, and months to create the greatest training benefit possible.

Good programming is not easy. It takes time, dedication, and hard work to do it right. But that’s our job, not yours. Gym owner, Joe Cebulski, was an Olympic-level Decathlete for Team USA and brings that experience and knowledge to 8th Day Gym daily.

All you have to do is come in, enjoy our welcoming team-like atmosphere, listen to our expert coaches, make some new friends, have a few laughs, give it your all. From CrossFit beginners to world champions, everyone is welcome at 8th Day Gym.

8th Day Gym has been home to elite CrossFit athletes for 7 regional and team CrossFit Games appearances as well as an individual world championship title! Athletes can scale 8th Day’s core programming down or up with coach guidance.
