Wells Street CrossFit is a must! The box is very clean, the WODs are tough and challenging, and will make you sweat a bunch! All of the members and coaches are welcoming and super friendly. But the best part about this box is the quality of the coaching staff. These people really know what they are talking about. One of the owners, Sean is a Chiropractor. The other owner, Stephen is knowledgeable as well and gave me so many great tips and ways to protect myself, while doing Olympic movements. Overall, this box was great. I will be going there every time I visit Chicago and I highly recommend you try it out as well.
