Miwa Natsuki, MA 

Founder, President

Miwa Natsuki, MA, began her career in the fitness industry in 2005 at UC Berkeley, when she was trained to become a Group Exercise instructor while pursuing her undergraduate degree. Since then, she has completed her graduate degree in Kinesiology, with a focus on education and behavior change, at Saint Mary’s College. Miwa now offers personal training, health coaching and various group fitness classes and workshops around the Bay Area. As a fitness and wellness educator and coach, Miwa’s goals are to help others achieve their health and fitness goals and to empower them with knowledge and skills necessary to be in charge of their health and fitness.

Creation of UrbanPlay is based on her research during her graduate studies, experience working with kids through various organizations and also her many years of experience working as personal trainer and health coach with the adult population. Furthermore, her passion to create UrbanPlay is fueled by her own transformation from being an overweight and sedentary kid.

Miwa is also the Assistant Director of Fitness at UC Berkeley’s Department of Recreational Sports, where she oversees various Fitness programs for students, staff and faculty. Recently, she opened Studio360, a personal training studio, with few of her friends where she offers health coaching and personal training. And she is also the co-founder of Urbankick, a kickboxing format that blends High Intensity Interval Training for a full body workout. 



Founder, Vice President

Shane Barnard, JD, is NASM, ACE and AFAA certified and the co-founder of Urbanplay and founder of Urbankick.  Shane has over 20 years of experience in the fitness industry but it was her work as an attorney for children in foster care that brought her passion for fitness to the younger populations.  She witnessed a growing health crisis among our youth and wanted to help by bringing education and movement to this under-served population.  She currently teaches at Crunch, Fitness SF and UC Berkeley where she is a health coach. Shane is a CEC provider for ACE and AFFA and honored ambassador for lululemon and Larabar.


Marc Beza

Web & Social Media Intern

I am currently a graduate student at St. Mary’s College of California, working my way towards a Master’s Degree in Kinesiology with an emphasis in Sport Management. I am a Bay Area native, having grown up in Walnut Creek and a HUGE San Francisco Giants fan.  I love being active and exploring the outdoors as well as being an avid sports fan, having participated in baseball, tennis, swimming, and water polo growing up. My love for physical activity and recreation is what led me here to UrbanPlay and I look forward to working with UrbanPlay and contributing to its success as much as I can!
