"Most gyms intimidate me. 9ROUND is not like that. With their supportive trainers & owners and friendly gym-goers, it’s been a welcoming community for me for 3 years now. Love ❤️ it!"
What members are saying
"I love all the trainers. I love that they take time to get to know you in between actually teaching you skills and techniques. I love that they push you to come out of your comfort zone, while still understanding where your personal skill level is. This is the most empowering group of people I’ve ever met. The work outs are different each time and push you. "
