Kalina’s Fitness | Teen Fitness and Weight Loss (ages 8-18)

Welcome to Kalina’s Fitness®

Leaders in Teen Weight Loss

Welcome to Kalina’s Fitness! I am Kalina Martinez. My husband Jorge and I have owned and operated two very successful teen weight loss centers. Together we have over 20 years of experience as leaders in the teen fitness and weight loss industry. We specialize in giving kids and teens (ages 8-18) all the tools they need to build healthy habits and transform their lives!

In our years working with kids, teens and their families, we have observed that the number one desire of all parents is that they want the best for their children but they do not know where to start. So if you are a concerned parent interested in helping your child to build healthy habits and reach their full potential then our program was designed especially for you.

At Kalina’s Fitness, we believe that every child should have the opportunity to lose weight and achieve their fitness goals. By combining nutritional counseling, support, and exercise, our program makes it easy for all kids and teens to become an amazing version of themselves. Start Today!

   “To empower kids and teens with the tools to build healthy habits that last a lifetime.”
