About Us


We are a team of independent and hand-picked Trainers supported by our team of Certified Exercise Physiologists and a Registered Dietitian who work together to get you results! Our health practitioners, fitness coaches and extended medical partners provide continuing education and resources as needed.

While most of our clients want to tone up, lose weight and gain muscle mass, we work with people at all levels, from professional athletes to people just starting out with exercise.

Our trainers are personable, smart, fun and outgoing. They each come with various backgrounds and experiences with training. They will listen to your needs and goals to continually check in to ensure that you're making progress, one step at a time. 

Together we will push you, but we won't yell at you! :)

Fitness and Weight Loss Health Practitioners



Our approach & what you get


Goal Setting & Planning

Your initial session is a 30-60 minute discussion about your goals, eating habits, injuries and exercise background. This time together gives us a chance to get to know you and what your goals and needs are.


Trainer's Assessment

We will pair you with a trainer based on our initial discussion who will then conduct a series of assessments which will help your trainer to develop your training program. Some typical assessments include; posture, movement screen, body composition, body measurements and range of motion.


Training Program

Your trainer will develop a progressive training program that will change, generally, every 4-6 weeks.  


Workout Plans

Depending on your goals, we will write out workouts for you to follow when you're not working with your trainer. We make them available online and they are mobile friendly so you can track your progress during your workout. Involved workout plans have an additional cost. 


Nutritional Coaching*

You'll be assigned to one of our nutrition coaches or Manuel Villacorta, Registered Dietitian, and together we will determine what to focus on nutrition-wise. We'll help you implement your program and provide support along the way. Our coaches follow safe and effective guidelines designed by Manuel Villacorta.


7-day nutrition plan* 

All of our clients get results by following EatingFree's 7-day meal plans. We will guide you through the process to determine your daily calorie goal and how to begin implementing a new program. There are a variety of nutrition plans to choose from, including: vegetarian, gluten free, vegan, low glycemic, and regular.


Behavior Coaching

We use behavior change and motivational interviewing techniques to encourage you in a way that is both positive and supportive. We will help you build upon your successes, progressively, with small change on top of small change. 


Weekly Reporting

We will check in with you weekly and ask you how you are doing with your workouts, with your nutrition and with things in general. Based on your responses we will support you as needed. 


24/7 - Ask Your Trainer Anything

You will have access to a secure page where you can ask your Trainer questions related to your program or just to get training support and encouragement when you need it.


Private Personal Fitness Page (see example below). *

We post all of your baseline photos, body composition and body measurements on your very own password-protected, private page on TrainerSanFrancisco.com. This helps us track your progress so you can see how you're coming along.

*Additional fee applies.
