SF DIAMOND FITNESS · ESTABLISHED 2000

Professional Excellence. Personal Attention. Every Client Matters.

I’m Rory Robertson, an Exercise Physiologist and founder of SF Diamond Fitness.
For more than 26 years, I’ve helped individuals improve their strength, mobility, balance, and overall quality of life through personalized exercise programs.
My approach combines professional expertise, decades of experience, and genuine personal attention. I believe fitness should be tailored to each individual’s abilities, needs, and goals.
Every client matters.

Every individual is unique, and every exercise program should reflect that. I design personalized strength and fitness programs based on your abilities, goals, health history, and lifestyle.
Whether your focus is building strength, improving balance and mobility, maintaining independence, or enhancing athletic performance, each session is thoughtfully designed to help you progress safely and effectively.
Enjoy the motivation and camaraderie of training with others while still receiving personalized attention.
My small group sessions emphasize proper technique, strength, balance, mobility, and overall fitness. Exercises can be adapted to accommodate different abilities and fitness levels, creating a supportive environment where everyone can work toward their individual goals.
Founded in 2000, SF Diamond Fitness combines exercise science, extensive professional experience, and a deeply personalized approach to fitness.
With advanced education in sports and fitness management, a background in collegiate and professional athletics, and more than 26 years of hands-on experience, I bring both knowledge and practical expertise to every training session.
I’ve worked with individuals of all ages and abilities, helping clients build strength, improve balance and mobility, enhance athletic performance, and maintain independence as they age.
My commitment is simple: thoughtful, individualized training built around each person’s needs, abilities, and goals.
I believe that fitness should enhance your life—not simply be another task on your schedule.
My approach combines exercise science, individualized programming, and an understanding of each client’s unique abilities, goals, and circumstances.
I emphasize strength, balance, mobility, proper technique, and thoughtful progression, while recognizing the important roles of nutrition, recovery, and overall well-being.
Whether you’re beginning a fitness program, managing age-related changes, returning from an injury, or looking to improve athletic performance, my goal is to help you move confidently, remain independent, and enjoy an active life.
Fitness is personal. Your training should be too.
At SF Diamond Fitness, I offer personalized exercise programs designed to help you build strength, improve mobility, maintain independence, and enhance your overall quality of life.
My services include one-on-one personal training, individualized strength and conditioning, balance and functional movement training, and small group sessions.
I work with adults of varying ages, abilities, and fitness levels, including individuals seeking to maintain strength and independence as they age, those returning to exercise after an injury, and athletes looking to improve performance.
Training is available in my private San Francisco studio, with in-home sessions available by arrangement.
Every program begins with you—your goals, your abilities, and your potential.

Every client is unique. I develop individualized exercise programs based on your goals, abilities, fitness level, and personal needs.
Whether you want to build strength, improve mobility, enhance athletic performance, or maintain independence as you age, your training program is designed specifically for you.
Strength training is one of the most important investments you can make in your long-term health and independence.
I design individualized resistance training programs to build muscle, support bone health, improve balance, and enhance everyday movement.
Whether you’re beginning, returning after an injury, or maintaining strength as you age, I emphasize proper technique, safe progression, and lasting results.
Cardiovascular fitness plays an essential role in heart health, endurance, and overall well-being.
I design individualized conditioning programs that may include indoor rowing, walking, interval training, and other aerobic activities tailored to your abilities and goals.
By combining cardiovascular exercise with strength training and appropriate recovery, I help clients improve stamina, enhance performance, and maintain an active lifestyle.
Personalized fitness training doesn’t have to happen in person.
My online sessions provide individualized instruction in strength, balance, mobility, and functional movement—all from the comfort of your home.
Each session is tailored to your abilities, goals, and available equipment, with the same professional expertise, personal attention, and commitment you receive in my studio.

For more than 26 years, I've provided individualized fitness training grounded in exercise physiology, professional expertise, and genuine personal attention.
Whether your goal is to build strength, improve balance and mobility, enhance athletic performance, or maintain independence as you age, I create a program tailored to your unique needs and abilities.
At SF Diamond Fitness, every client matters.
Strength, balance, and mobility are essential to maintaining an active, independent life.
As an Exercise Physiologist, I design individualized programs that help clients preserve muscle strength, improve stability, and move with greater confidence.
My approach is especially valuable for older adults who want to remain active, reduce their risk of falls, and maintain their independence.
Aging is inevitable. Losing strength and independence doesn't have to be.
Some of my clients have trained with me for more than 25 years. These lasting relationships are among the greatest rewards of my career.
I believe successful training begins with listening, understanding, and building trust. Through life's changing circumstances, I provide personalized guidance, encouragement, and consistent support.
My clients are more than appointments on a calendar. Their health, well-being, and quality of life genuinely matter to me.
No two clients are alike, and neither are their training programs.
Whether you're beginning a fitness journey, returning after an injury, or pursuing athletic excellence, I take the time to understand your health history, abilities, lifestyle, and personal goals.
My philosophy is simple: Meet you where you are, challenge you appropriately, and help you become stronger, healthier, and more confident.
My passion for fitness began as a nationally recognized high school basketball player, leading to a Division I scholarship at the University of Colorado Boulder and opportunities to compete professionally.
I earned my bachelor's degree in Physical Education from UC Berkeley and my master's degree in Sports and Fitness Management from the University of San Francisco. I was also inducted into the Napa Valley Athletic Hall of Fame.
Today, I bring a lifetime of athletic experience, academic knowledge, and professional dedication to every client I train.
At SF Diamond Fitness, every person deserves to feel valued, supported, and encouraged.
Progress looks different for everyone. Whether it's gaining strength, improving balance, rebuilding confidence, or simply moving through daily life with greater ease, every accomplishment matters.
After more than 26 years, my greatest reward remains helping people live stronger, healthier, and more fulfilling lives.
