What people say about us

“Crossfit 30004 is great ”

Crossfit 30004 is great. The instructors are top notch; super helpful and friendly. They know how to both push you and give you the right jolt of encouragement just when you need it. I am really just a novice at this point - but I got my wife to join, and we are looking forward to being our best selves under the guidance of Jonathan and team.

“You succeed not only physically but mentally”

We had been looking for our new CrossFit home when moving to Alpharetta in 2016, it took us a bit, but we found it! The coaches are very patient and helpful and the other members welcomed us with open arms! I would recommend CrossFit 30004 to anyone looking whether new to CrossFit or veteran! This gym has shown me during the past few months that they want to see you succeed not only physically but mentally.

"highly recommend"

Crossfit 3004 has an awesome and fun community. I’ve found it easy to be consistent and improve because of it. We push each other and hold each other accountable. Coaches are very experienced and very attentive. Highly recommend!
