Sarah Michelle

Age 34 • Personalized Training

After 20 years of struggling with my weight, DefineIt changed everything. The personalized approach made all the difference. I’ve not only lost 40 pounds but gained incredible strength and confidence.

Robert Chen

Age 52 • Greater Than 50 Sessions

I thought it was too late for me to get in shape. The team at DefineIt proved me wrong. Their specialized program for people over 50 is incredible. I feel like I’m 30 again!

Maria Gonzalez

Age 28 • Virtual Training

As a busy mom, virtual training was perfect for me. The trainers are so supportive and professional. I’ve never felt stronger or more energized. The lifestyle coaching was life-changing.

If you are looking for a supportive environment to get in shape and stay in shape–this is” it! Shari is a great trainer and you will make working out an essential part of your life and schedule.

I was in a fitness rut when I started seeing Shari at DefineIT. I had been going to the same Dailey Method / Bar Method classes that I had been taking for years, but I had stopped seeing results. After six weeks working out with Shari at DefineIT, I can see the change in my body and I have never felt better. Shari’s workouts are strategic and efficient – I love that when I leave, I know she has maximized my time with her. As a trainer, Shari is knowledgeable, motivating, and supportive. Highly recommended!

Shari changed my life! I lost 10 lbs in the first six weeks on Shari’s intensive program. Now 20 lbs lighter, I am proud to thank and give credit to Shari for giving me the tools, guidance and motivation to succeed. Shari reshaped my body, but more importantly, Shari taught me about portion control, moderation, and how to get the best results in the least amount of time. For years, I struggled. Little did I know, I was doing the wrong types of exercises, in the wrong way, and I was eating way too much. I hope you choose to be WOW’d by Shari and that you too will change your life.

I have been training with Shari for over 10 years now. I started when I was 35 and at a point where I wasn’t happy when I saw myself in pictures or my reflection in a window. I wasn’t the me I knew. I met with Shari and felt instantly comfortable and motivated by her. Training with Shari is great. She does all the thinking for you and you just show up. You feel great when you leave and can’t believe how weight training and food coaching really makes a difference. Oh, and she is also a great friend through it all–coaching, encouraging, and giving sound advice to help you achieve your goals.

Betty T.–Belmont

I am more convinced than ever that the reason I was able to heal so quickly from 2 surgeries and chemotherapy was because I had been exercising regularly and maintaining a proper diet before I got sick. Throughout my chemotherapy, I was able to exercise to promote healing and the mental and emotional benefits of working out with my trainer greatly contributed to my wellbeing. My physicians all commented on how fast I healed! Don’t get me wrong, I had days where I felt really bad and weak. However, going to a place where I felt safe, the environment was clean, and my trainer working with me at what ever level I was able to manage at the time gave me encouragement. I am done with my treatments and feel like I am in the best shape ever because I stuck with a health program leading up to, during and post treatment. You may already have a fitness program, trainer and center where you like to exercise. If not, I whole heartedly recommend my fitness professional, Shari Gower. She’s located in San Carlos and I’ve attached a link to her information here. (She also does a great 2 week intensive programs to get one jump started and mentally geared up for a lifetime of health.) My main message to you is to do whatever it takes to put yourself first, support your body and allow it to support you as you move forward in your professional career.

I have been working out with Shari for close to 10 years.She knows her stuff! She is always changing our routines so I do not get bored-She is smart, kind and an asset in my life for sure! I may not like going to the gym, but once my hour is over i can check it off my list, and feel really good about it. Her new gym in San Carlos is such a treat. All of her equipment is state of the art. It is super clean and bright and private. I highly recommend Defineit.
