“First thing, I love this place! And I would recommend it anyone looking to make a positive change in their life. I have been with the school for about 3.5 years now, and it has become a second home for me. The instructor, David, is awesome. I've been coming 2-5 days a week for the jiu jitsu program since I started, and everyday is always something new and fun. But my favorite thing about Knuckle Up has got to be the people here. From the very first day I walked in the door I felt welcomed, everyone is always very friendly and willing to help me whenever I need. So anyone looking for a fun and engaging way to workout, just come in and visit us.”
“Wish my experience was better. I emailed inquiring about Jiu Jitsu and received a call back 4 days later (which I was unable to answer). Called back the following day and was greeted with an agitated "hello?". After confirming I called Knuckle Up we unfortunately had cell connection issues which further agitated the man on the phone. He called me back and we spoke briefly about classes but after one smart remark too many I asked his name (David) and told him this gym isn't for me. I wish David had mediocre phone skills, suggest hiring a dedicated secretary. Recommend anyone inquiring this gym to see David in person because he may be a decent guy, but I'll never know. I can't waste the time - deal with enough "macho" men in the military.”
“I have been taking the kickboxing class since January 2014, without becoming bored or losing interest in going. My overall level of fitness has increased drastically! I toned & firmed up those female problem areas, while enjoying what I was doing! I could not imagine going anywhere else. The schedule of classes works well with any schedule you might have. The owner & the other students are always willing to help you out and are totally supportive of each other.”
“On my first day Here I was family. not only did I get great training I had fun learning more about the history and background of Brazilian jujitsu. the group at this place became my friends and motivators not only in this sport but in life my son loves it and to see him light up about going just made me want to go more and more if your looking for A great experience this is the place to try.... we love it”
