Fantastic experience: Training is difficult when traveling from Texas, especially when I’m not sure if a gym will let me drop in. I loved that their website has a drop in option! On top of that, I train for powerlifting and strongman and they were very accommodating! They have lots of tires, stones, and a couple yokes. I was able to do any free weight exercise I needed to keep getting stronger. This will for sure be my gym when I’m visiting family (and will be my gym if I ever move back).

Fantastic experience: My wife and I dropped in to Thunder Valley Crossfit this morning for the 6:30 class while passing through Johnson City on a road trip. It was definitely one of the best boxes we've trained at on this trip. The facility is awesome, the other athletes were very friendly and Brad, the coach/owner was super welcoming, super professional and super encouraging. Would highly recommend if you're passing through town and need a place to train, if you've just moved to JC and are looking for a box, or indeed if you live here and are thinking of starting Crossfit for the first time.

Fantastic experience: I had a great experience at TVCF this morning! I contacted their box about being able to do my weightlifting programming there while visiting from out of town. They were quick to reply and very welcoming. I was surprised to see what a great setup they have for weightlifting -- platform, kilo plates, jerk boxes, blocks, etc. They even took out a 15kg bar ahead of my arrival and set it in the weightlifting area so that it would be ready for me. Very impressed!
