Robert Santana is a Registered Dietitian and Strength Coach and owner of Weights & Plates Gym in the Greater Phoenix area. For the past two decades, Robert has developed and refined his knowledge, skills, and experiences through both higher education and practical experience. Robert earned both a Bachelor of Science in Dietetics and a Master of Science in Kinesiology at Western Illinois University. His quest for knowledge and a deeper understanding of the scientific process led him to earn a Doctor of Philosophy in Nursing & Health Innovation at Arizona State University. 

He has extensive experience as a strength coach, nutrition coach, researcher, teacher, and competitor. He built upon his foundational knowledge by providing effective nutrition coaching in conjunction with teaching and coaching the barbell lifts through the application of the Starting Strength model of performing barbell exercises to help clients move safely while getting stronger and building muscle. As a firm believer that one must experience that which he or she is coaching, he has served as his own “guinea pig” experimenting with various diets, training programs, and has competed in the sports of Strengthlifting, Powerlifting, and Olympic Weightlifting. His key goal has always been to continuously build muscle, while minimizing fat gain, in a functional and sustainable way.  Integrating elements of all the various lifting approaches has enabled him to help clients achieve their body composition goals while becoming more functional human beings.

Why did you start coaching? My father was an avid lifter and took me to an old school weight room when I was 10 years old, and I could not wait to be old enough to train. In my early years in college, I spent more time learning about lifting and nutrition than my academics, which led me to switch my major. At age 19 I knew I wanted to coach people both on diet and exercise and saw the value of becoming both an RD and a strength coach since I saw the integration of both skills as essential in an industry dominated by marketing hype and in need of scientific knowledge. I coached anyone I could to gain experience and eventually my goal materialized years later. To this day, it never gets old to see my clients overcome big obstacles and achieve things they previously thought were not possible.

What is your coaching style? I challenge my clients while meeting them where they are. I can be tough while also empathizing with my clients' unique challenges. Difficult challenges require difficult choices, and it is important to me that my clients understand what the expectation of their journey is. Providing the most accurate information in a clear concise way, while maintaining accountability is the cornerstone of any successful coaching relationship.

What kinds of clients do you work with? Clients who want to increase strength, build muscle mass, and lose body fat in a functional and sustainable way that is compatible with their lifestyle and preferences.

What is your favorite part of coaching?  Watching my clients overcome mental blocks and lifestyle challenges to achieve their goals. Nothing makes me happier than to hear a client say that they cannot believe they achieved something they previously thought impossible. Seeing people learn and experience new victories never gets old and is my pride and joy.

What type of client would be the best fit to work with you? I work with a variety of clients interested in getting stronger, building muscle, and losing fat or maintaining fat loss. As an RD, I’ve worked with a variety of different medical conditions and have several years of clinical experience in an inpatient and outpatient setting. 

In terms of training, I can train people with a variety of widely available exercise equipment for hypertrophy and/or strength. I’ve trained people of all ages, including youth and older adults. I am no stranger to movement limitations and am proficient at programming around and or rehabbing a variety of musculoskeletal injuries. 

In terms of competitive lifters, I also have extensive experience training strengthlifters, powerlifters from novice all the way to advanced lifters. I have also trained various endurance athletes with off season strength programs and strength maintaining programs during their competitive season.

What You'll Get

Choose from plans structured by an RP coach, each tailored to achieve your specific needs and backed by science. Whether you opt for a diet plan, a training plan, or a combination of both, you'll receive 1:1 expert guidance from your coach via email exchange with very little left to chance.

  • Diet Plan: Focus on your nutritional goals with a customized diet plan. Your coach will help you dial in your macros, whether you aim to lose fat or gain muscle. Full meal plans/recipes will not be provided but you will receive guidance on the proper amount of protein, carbs, and fats to consume daily with a list of recommended foods!
  • Training Plan: Focused solely on weight training with a plan designed to fit your fitness level and goals. Please check with our help desk if you have sport-specific training goals.
  • Combo Plan: Get the best of both worlds with a plan that integrates diet and training for comprehensive progress.

With all plans, you are expected to proactively check in with your coach twice a week with updates and questions. It's important to note that the coach will respond to your updates rather than initiate contact on their end. Your coach will monitor your weekly progress through these check-ins and make any necessary adjustments for you based on your feedback.

You'll have unlimited email access to your coach, ensuring you get timely responses to your queries: within 24 hours on weekdays and 48 hours on weekends (May vary based on the coach's schedule). Your feedback and questions are necessary for your coach to make the most informed decisions on your behalf for your plan so do not be shy about contacting them for help!

Please contact our help desk or refer to our FAQ below if you have any further questions about our services!
