TESTIMONIALS

I have been going to Kings Fitness since 2003. Kamron King, the owner has helped me throughout the years, he has given me great workout advise and helped me stay consistent with my fitness goals. Kamron takes care of his members and takes the time to greet you if you are at the gym, he makes sure everything is up to par with member expectations and keeps you motivated to work out. I would recommend this fitness and training facility to anyone looking for a comfortable place to reach your training and fitness goals. They have indoor and outdoor workout spaces as well.

Working out at King's gym is awesome. I love it because everyone is so welcoming and friendly. It's not a gym where you're being judged, so you don't have to stress over what you look like . They have every machine you could possibly want, plus they have an outdoor area to work out. It's perfect for cool mornings. Kam and all of the trainers are super nice and always willing to help .

I have been going to King's since my freshman year in high school. I started going because all of my friends were training there. After being at King's for a while I realized Kam has a lot of knowledge and experience that has been very helpful in my development as an athlete. He takes a genuine interesting all of the members. There is no other gym like King's Fitness in the area. I look forward to training there whenever I am home.
