Getting started is as easy as coming in to our free intro class or trying out a free trial class. You can sign up for a time on our website at NSXFit.com If you need any help please email us at ([email protected]) or call (509.845.9796)

Our free intro is a quick chat to answer any questions you might have. Before you sign up first ask yourself: Am I ready? Am I ready to sweat and learn? Am I ready to embrace the uncomfortable as my new comfortable? Am I ready to become a better person and live a better life? Am I ready to live a healthier life? CrossFit is designed to push you to your mental and physical limitations. Once they are reached we will push you passed them, breaking you apart and rebuild you (in a fun and enjoyable way), we will have you doing things you have never done before or ever thought you could do. Once you have completed the free trial class your coach will guide you through the next steps in making you the athlete you are striving to be. During our visit if you have any questions please don't hesitate to ask.
