Fantastic experience: I joined this crossfit box almost three years ago in order to improve my triathlon times. Little did I know that I would fall in love with the people and the programming. Everyone is so helpfull, supportive and encouraging. This has become a second home and a second family. If you’ve had reservations and/or doubts about trying crossfit, don’t. Come here where everyone will make you feel welcome and will Motivate you to push harder than you ever have before.
