Julia Walderzak, Owner

Screen Shot 2013-04-21 at 9.18.35 PMJulia Walderzak is the founder of H2K Happy Healthy Kids Fitness Studio. H2K is a unique fitness studio that specializes in non-competitive fitness for children and families. They offer kids yoga, kids cardio dance, kids kickboxing, kids circuit training, mom and baby yoga, cardio dance with your toddler, teen classes, camps and healthy birthday parties.

Julia began her career as a corporate event planner, but felt unfulfilled. As a child, she struggled with her weight and hated competitive sports, so she taught herself how to get fit and maintain a healthy lifestyle in other, non-competitive, ways. Knowing there is a huge population of children and families that are currently struggling with the same issues she had overcome, Julia developed the concept for H2K. H2K was created in hopes of helping these families, who have been under-serviced in the past, learn how to live happy, healthy lives.

Julia currently has her 4th degree red belt in Tai kwon Do and also has certifications in Zumba, kids Zumba, kickboxing, radiant child yoga levels 1-3, and Yoga for Children with ADHD, Autism, and those who are Differently-Abled. H2K’s main center in located in Arlington, MA with satellite locations in Maynard, Natick and Concord. H2K also offers a variety of mobile classes statewide.
