We believe that eating right shouldn't be so d@*# complicated!

Simply put, 9Round Nutrition is eating the right foods, at the right times, in the right amounts. Improving your body composition takes patience, persistence, and consuming the right fuel. That is how you perform like a champion.

Inside this program, you will finally learn: 

  • How many calories your body needs to function optimally (customized for your needs)
  • How to control your eating frequency to curb hunger and stabilize blood sugar (no more afternoon slumps)

    I was a 9Round member and decided I couldn't get enough of this workout, so my wife Missy and I decided to open our own gym! I have always loved fitness. I played a year of college football and had always lifted weights until I found 9Round. The resistance from hitting the bags combined with the cardio and the convenience of the 30 minute workout has been a life changer! I'm getting better results compared to my prior workout routine and it only takes 30 minutes. I can't wait to share this experience with you! Brandon

    I have been in the US Navy as a Nuclear Engineer for 14 years now. I have traveled the world and continue to do so today. I joined 9round because I could never seem to add cardio to my normal workout routine. I decided to walk into this kickboxing gym and talk to Brandon, and was intrigued as soon as I walked in. I have been a member for six months now and have already seen improvements in both technique and form. The workouts are fun, convenient, and always different. As soon as I completed my first workout, I knew that this would be something that I would love to teach as well.

    I moved to San Diego almost two years ago from North Carolina. I have always loved sports! i played volleyball and soccer since grade school. I was a soccer coach in college and played almost every rec. sport there was! Before joining 9Round as a member the only equipment I used at the gym was a treadmill. When I first joined 9Round I told Brandon I wanted to build my upper body strength. After only a week I noticed I finally started to get muscles!! This gym is not only amazing for cardio but toning your body. Take it from me - I was a member and experienced it first hand!!

    Lauren "Lights Out" Witeck
    I am a proud Navy spouse and momma of an extremely energetic 7-year-old! After moving from Washington to New York to Japan to California, I have finally gotten myself back in college. I’m getting my degree in the Health Information Technology program, and can’t wait to finish and get started the medical field. With the busy, dynamic life we lead, I was very excited to discover a workout that fit into my schedule! Only 30 minutes, at any time of the day? Can’t beat that! After months of being a member and getting to know the fantastic team that works here at 9Round, I was ready to jump in and give other members a great workout! I’m excited me meet all of you and get you sweating!

    I love to workout, am passionate about fitness, and nutrition. I tried multiple workouts and find it hard to stay interested, that is until I discovered 9Round! The workouts change daily, keeping me engaged and I have full access to personalized nutrition. Not to mention there are NO CLASS TIMES which fits perfectly into my crazy schedule! Can it get any better? I can't wait to share this passion with you!
