This place is seriously THE BEST. I’ve been to a number of boxes and Fortius stands about amongst the rest. The coaching is top notch and the community is unlike anything I have ever experienced anywhere else. I remember my first day, I was blown away by how friendly everyone was – I thought to myself, so THIS is where all the nice people hang out!
CrossFit literally changed my life and Fortius is where it all started. I couldn’t be more grateful to the owners Jesse & Dave for what they have created here and the confidence they have instilled in me. I never thought I would say it, but for the first time in my life, I feel like I can call myself an athlete.Rachel R.
What can you expect? I joined/participate in the crossfit side of the house. They also offer an Olympic lifting membership. I was nervous about joining a crossfit gym. I heard all the cultish rumors and stories of injury. Turns out, it kicks ass. It is a great combination of Strength, Stamina, Skill and Conditioning. Each workout starts with ample time to warm up and get stretched out, followed by a “skill session” where you practice skills related to crossfit, followed by a strength section (the only part I am good at) and you finish off with the actual workout of the day or WOD.Tom C.
Thinking about trying CrossFit in the new year? I highly recommend CrossFit Fortius! In full disclosure, I’m a 58 year old woman. They have workouts for all athletic levels and offer a full week free to try it out. Can’t beat that! I’ve enjoyed exercise all my life, but never joined a gym – until now.Diane N.
