Transferring from Another Affiliate?
Athletes transferring to CFSBK should have appropriate CrossFit experience (about 3 months or more). CFSBK reserves the right to reevaluate a membership if a coach has concerns about movement quality that could compromise athlete safety. In these rare instances, staff will communicate directly with the athlete and may require a private session or Foundations enrollment.
Transferring athletes may sign up with any of the membership options below.
