"There's no easy way to fitness"


Exercise and sports have been a part of Seth’s life since he can remember. After keeping active in highschool and collegiate sports he was looking for something different…getting involved in boxing, trail running up to half and full marathons on a competitive level. There was still something missing until he found CrossFit. Everything pretty much came together after that. Although he still loves the other activities and sports, CrossFit is his focus and is why Seth is now in the best shape of his life.


There’s more to working out than to just blasting through each exercise, realize there is a mental game to CrossFit as well. We’re here to get you through all aspects of CrossFit, mentally and physically.
