About Aaron

Hi, I'm Aaron and I have been training for over 15 years, helping clients gain muscle, tone up and lose weight! I am the owner of TRAINER SF which launched in 2015 in the Mission Dolores District, and we expanded in 2017 to a 3 story fitness center with an outdoor training space in Mission Bay.

I work with people at all levels, from professional athletes to people just starting out with exercise. I have a degree in Exercise Physiology plus many years of experience working in both outpatient and inpatient physical therapy clinics.

I am very personable, smart, fun and outgoing. I will listen to your needs and goals and help you get there, one step at a time. I have a background in coaching so I will be able to help you make those small behavioral changes to get you to your goals. I will push you, but I won't yell at you! :)

My approach and what you get

Your initial session will include an extra 20-30 minutes where we will discuss your goals, eating habits, injuries and exercise background. I will conduct an assessment where I will look at your posture, biomechanics and range of motion that will help with developing your training program.

I will spend time listening to you explain where you are currently with your overall health and fitness. This will help me to determine the best approach for your goals and the optimum starting point. 

I will offer best-practice options for incorporating nutrition and exercise into your daily life based on my education and experience working with hundreds of clients. Together we will agree what will work best for you and you'll feel confident with your next steps. I want you to get the results you want!

I offer a variety of training packages with the following options:

  • Access to a password-protected, private page on TrainerSanFrancisco.com where I will post your baseline photos, body composition measurements, and other information that will be helpful in tracking your progress
  • Workout plans to follow on the days we are not training
  • A full nutrition program and complimentary coaching
  • Support and encouragement when you need it
  • truly private studio for your training sessions (you and I will be the only ones training in the space together)
  • Instruction on proper form and technique
  • A proven methodology for behavior change using motivational interviewing techniques and Tiny Habits
  • "24/7-Ask Me Anything" access to a secure page for training support and motivation
