Sandbox Fitness was founded in 2014 by David and Minna Herskowitz. Together, Minna and David have more than 30 years of fitness experience. This husband and wife team have been working out at the beach for years and noticed that sand training was the only workout that did not have a negative affect on their joints. Although they dont live far from the beach it was still a good drive, so decided to bring sand training indoors and introduce it to the public. They hope you enjoy it as much as they do.
Minna is an East Coast girl from Maryland whose passion for fitness started in high school. That was when she realized that a good diet and exercise were the only ways to fit into a dress for her sister's wedding. Shortly thereafter Minna became certified as a personal trainer through the National Federation of Professional Trainers (NFPT). While working as a fitness trainer, she studied Nutrition and Exercise Science and Business at Queens College in New York. In 2010 she moved from the Big Apple to Los Angeles to be closer to David... and the beach, of course. She has extensive experience training people of all age groups, from children to the elderly, as well as people with injuries. Her specialities are TRX ®, Surfset ®, strength and conditioning, Bootcamp, Zumba, dance, and kickboxing.
David was born and raised in Los Angeles and has been working in the fitness field for over 15 years. David also worked for Natrol and Prolab which has given him the tools to design personalized workout and nutrition programs for his clients. David specializes in strength training, circuit training, TRX ®, Surfset ® and bootcamp. David also teaches an expansive array of self-defense classes and strategies. Having trained with law enforcement, David brings a breadth of unique experiences and techniques to his classes.
