In their words

“I am blown away by this community, when my wife and I started going here they took us right in and made us part of the gym family! We have reached so many goals and built so many friendships!“
— Caleb Stauffer

I just hit the 1-year mark. This is the first fitness program I have ever stuck with for longer than 6 weeks! I am not even a fitness person and I can’t wait to go every day. The people are so fun and encouraging. Amazing coaching. RESULTS. I have lost 20lbs. Made so many new friends that we are connecting with outside of the gym. Honestly, it’s one of the best things that has happened to us in the past year. We love it a weird amount. Come join the community! It’s literally the best.
– Jenna Jones

Absolutely love the people here. I have made some pretty great friends through this place. Non-judgmental community and super inviting!

Justin Williams
Owner, Coach, Personal Trainer
I was born and raised in Billings MT where I grew up competing in gymnastics, football, basketball, baseball and track & field. After high school sports, finding something to feed my competitiveness was hard, until I was introduced to CrossFit in 2009. I fell in love instantly with the competitiveness and community CrossFit offered.
I got my level 1 CrossFit cert in 2018 and have coached at multiple gyms in Billings helping members work towards their goals and break down barriers as well as running a gym with my wife in beautiful Costa Rica. Since taking over Iron Den in 2021 I have been fortunate to meet some of the most amazing people and look forward to growing our great community!
