“Feel the fear, do it anyway”- Jo-Ann Houston shared this quote at GG training
After I had my two children, I was on a mission to get back in shape. I started going into the gym and my husband Brain helped my with programming for weight loss and muscle building. I was also focused on nutrition. I got in the best shape in my life and started empowering others to do the same! I have played all types of sports but found my passion in Dance. I am trained in ballet, tap, jazz, hip hop and modern dance. Last year I found a great passion in Pole Fitness and now I train twice a week!
My mission is to build a business that empowers our clients to change their lives and be the healthiest they can be! We are all about enhancing our clients lives by motivating them, holding them accountable and providing support in them most loving and compassionate way.
My husband Brian, is a co owner and while he has a full time job in the staffing and recruiting industry, he is a constant help and support in operating GYMGUYZ! He is my rock and his ambition and energy is an inspiration to me. On June 17th we are celebrating our 11 year wedding anniversary and 12 years together! He loves mountain biking and swimming. Brian is the most amazing father to our children and the greatest partner a woman can ask for. My favorite thing about him is his unwavering loyalty to me, our family and the life we have built together.
My daughter Layla is about to be 7 years old and she loves art, reading, swimming, gymnastics and dance. Her athleticism constantly surprises me and her kindness towards others makes me beam with pride. For being so young she has such a strong sense of responsibility and need to do what is right. Layla is always ready for the next adventure, loves to travel, loves to be around the ones she loves and she is so intelligent.
My son Jack will be 4 in September and he loves swimming, and building and creating things. He has such an outgoing personality and his humor makes me laugh out loud everyday! While he has strong opinions he is so loving and affectionate.
In being a parent, what I most proud of is the value my children place on our family unity! My son is always talking about how we are a team and my daughter places the utmost emphasis on our family bond.
I am a certified fitness trainer and plan on getting a certification on nutrition as well!

Hello, my name is Aaron and I specialize in strength training and body transformation. Whether you are looking to lose fat, build strength and muscle, or improve structural integrity and flexibility, I am happy to provide a direct path to your goals! I came to love training several years ago at a time when I was chronically ill. Through training I have learned and reaped so much that has empowered me to overcome adversity. To that end, I remain committed to evidence-based knowledge as well as compassion and empathy. I know what it is like to start a fitness journey and feel so far from your goals as I was bed-ridden many years ago.

Anne Lamott’s writing and humor remains a constant joy in my life. Not only does she make me laugh she reminds me to add levity to life.

I love to bike, hike and run and when I have extra time to myself I enjoy paddle boarding. Having young kids and an adventuresome husband keep me very active too!
Jean-Michael Certified Personal TrainerJean-Michael Certified Personal TrainerHello My name is Jean-Michael, people often call me J-M. I have grown up and lived in Marin my entire life and have a health conscious awareness.
I have had 5 years working as a fitness instructor/trainer. I used to practice teaching Crossfit, Parkour, basic Martial Arts, and Gymnastics. I train all ages in learning how to enhance their movement and quality of life, while also learning how to have fun! I have a certification as a Gymnastics Instructor and am a CPT under NASM.
My favorite Quote comes from Einstein, where he says “Insanity is doing the same thing over and over again and expecting different results.” I try to incorporate this with new exercises, techniques or skills to learn daily. Mixing up exercise patterns has always been fun for me, and it keeps it interesting for those around me as well!
I exercise everyday. I make habits that allow for growth each day, with little improvements overtime. By biking, practicing gymnastics, weightlifting, learning a new skill, playing with my dog, and even joining in with my clients! I am never stuck in place for more than a day.

Growing up an athlete, I had my fair share of coaches and trainers, and naturally my passion for health and fitness lead me to want to follow in their footsteps. I made it a lifelong goal to become a great personal trainer (and later, a great physical therapist), so I started small: training my teammates, other sports teams, and friends/family. My ability to connect with people, willingness to learn, and drive to work with and for others has allowed me to excel as a trainer. I’ve been training for 3 years and I’m currently working on two NASM certificates: Corrective Exercise and Behavioral Change. The progress and success I’m able to help my clients achieve motivates me to continue working on myself - I strive to give others my very best, while pushing them to be their best!
Favorite Activities to Stay in Shape:
Boxing (if you’re interested in shaking up your cardio game, I’ll gladly teach/do mitt work with you!)
Corrective Exercise Yoga/Stretch Routines
Any Outdoor Activities Tracking Macros (dietary)
I’m constantly looking to expand my horizons, broaden my health/fitness knowledge, and push my comfort zone - so, if you happen to be looking for an adventure buddy - I’m ALL IN. :)
