About Holly

Holly Roser is a certified Personal Trainer and a certified Sports Nutritionist in New York City and San Francisco. She has 13 years of experience in fitness, including 10 personal training certifications.

Holly’s mission is to fight against the climbing obesity rates in America by encouraging people of all ages to start with small steps towards a healthy life.

Holly is regularly featured in the top websites and broadcasts in the country as a fitness personality. Her unique training style and infectious spirit have captured the audiences of the Dr. Oz Show, Self Magazine, Shape Magazine, Men’s Fitness Magazine, Total Beauty, Home and Gardens Magazine, Prevention Magazine, The Washington Post, NY1 News, KTLA, Livestrong, EHow, Brides Magazine among others. She is proud to be a fitness writer for Livestrong, delivering the latest workouts to busy professionals.

In 2014, Holly created Girl Fit, a non-profit after-school program, for 37 Fairfax High school students in Los Angeles, CA. The focus of the program is to motivate and inspire inner city, low-income teens to eat healthily and create a career path for each girl. Girl Fit is catered towards girls ages 13-18 where girls learn goal setting skills and how to live a confident and healthy life. Workouts are catered towards teamwork and focused on well-being instead of weight loss. Holly’s goal is to provide the tools for girls from low-income families to succeed in all areas of their lives while ensuring they have access to healthy foods and the knowledge to make the best food choices.

In her free time, she loves running up hills in San Francisco and going on walks with her two Pomeranians and husband Johnathan.
