About us

Donato Malavarca has been in the fitness industry for over 30- years. His keen understanding of how the body moves and functions comes from years of training himself, in weight training and in martial arts. His inherent love for fitness and patience for helping individuals meet their goals is what makes him an exceptional trainer.

Donato is originally from New Jersey. In 2002 packed up everything to move to San Diego. He had a trailer full of gym equipment, a blueprint of what he wanted his gym to look like (which he had drawn over 10 years prior to moving) and his vision of what was to become F-max Fitness. 

Donato has developed a loyal following of clientele since F-max was opened in 2002. He trains everyone from kids to athletes. He is a strong, positive influence over everyone that works with him as well as a huge success rate for results-oriented individuals.  F-max is continuing to grow, and Donato has as much passion for his work as he did over 25 years ago.

All About Us

Karen’s first taste of the athletic and fitness world happened when she was in her first gymnastics class at the age of 3 and a half. Since then being active and helping others be active has been an integral part of her life.  At first Karen tried a career outside of the fitness world, but that quickly lost any appeal. Karen’s passion for living a healthy, active, full life comes from deep within, and there is no part of her life that does not interact with that passion. She enjoys helping others to become active, to challenge themselves to see how far they can go, return from injury, and to maintain fitness through out life.  She believes that physical activity should be safe, effective, and fun.  She has a strong yoga background, and believes that the physical, mental, and emotional aspects of wellbeing go hand in hand with each other. Karen enjoys the challenge of training many different populations in both a one on one setting and group settings in a number of modalities.  She wants people to enjoy their workouts, to feel comfortable working out, and to know that they are capable of achieving their goals.
