“Body by G is a constant in our household.  A place where my family has become part of a close-knit community.  Giulia has guided my children in developing and achieving their goals, not only for their respective sports but more importantly in their everyday life choices.  G’s coaching provides them with the information they need to promote endurance, build muscle, view food as fuel, and know that leading a healthy life begins way before adulthood.   It takes a village to raise a family and we are fortunate to have Giulia living in ours.” – Elizabeth Koch on behalf of the Koch family.

Client Spotlight: W.A.

I’ve just returned to training with Coach G after taking a three-year break during which I had a baby. I was working with her for about a year before that. I couldn’t be happier to be back. I never thought that I’d be working out consistently, much less with personal training and advice. But it is not an exaggeration to say that training with Coach G has had a huge positive impact on my physical and mental health. (more…)

Client Spotlight: Alice Flinn Campbell


“Coaching By G is a private owned fitness studio located in Oak Park, Illinois. The owner, Giulia Isetti, is not reluctant to let you know the truth. Honesty and truth are extremely important. As humans we have to believe and accept what is true but also what is false. Aristotle once said, “To say of what is, or of what is not that it is not, is true.” More lightly put, the world provides two things, what is and what’s not. Thus the truth and falsity. I believe this quote is embedded in her personality and this makes her an even better fitness coach. 

Giulia Isetti’s studio is a combination of blue and orange colors as well as a combination of clients from the age of 10 to 83. Her clients are all different types of athletes. Rowers, hockey players, volleyball players, swimmers, runners, soccer players, baseball players, basketball players, field hockey players, and people just looking to strengthen their bodies. These clients provide a sense of community and kindness. Her dogs also help to provide these ideals. Her two dogs, Roadie and Lili accompany Giulia to work. They greet you with a friendly smile and tail wags as you walk through the door and they defend the studio from squirrels and other riff-raff at all costs.  (more…)

Client Spotlight: William Godellas

I’m William Godellas, a 14 year old baseball player who struggles with engaging in a lot of things. I started working with Giulia a little over a year now, and I have no words to describe how life-changing her program has been for me.

The original reason I started at Coaching by G was to gain weight. I came in for my consultation at age 13, 5’0 and 80 pounds. Gaining weight had been hard for me as I never had an appetite and had always been a picky eater. Flash forward a year, and I am 5’9, 125 pounds. Her personalized workout plans and dietary help has been outstanding for me. Not only has her program helped me physically, however, it has also done so much for me mentally.

When school got tough, with studying habits and sleep, Giulia was always there to guide me and help me succeed. I know that if I were to ever need advice for anything, Giulia would always be there for me. Not only her, but the community that she has developed inside her studio. You cannot always pick and choose your clients, but Giulia’s clients all feel like family. (more…)

Client Spotlight: Mari Wolkstein


Mari Wolkstein is a competitive hockey defensewoman. She is small but mighty.  It has been so much fun to watch this young athlete develop physically and emotionally. Mari has grit. She is determined with a deep sense of purpose.  She is an athlete who needs no external motivation, because her engine is fired deep within. That level of motivation, a strong inner force that causes behavior, is a rare quality in anyone – but especially someone of Mari’s age. Her athletic achievements are astounding. She is not only training with Coaching by G 4-6 days a week, but playing hockey as much, traveling to tournaments, a rockstar in the classroom, an avid reader, guitar player, and much more.  Mari is an example to everyone in the gym: she is not waiting for her life to happen, she is actively engaged in designing the life she wants. (Are you struggling with designing the life you want, specifically when it comes to diet? Here’s a whole bunch of nutritional know-how to help you harness the power of your biochemistry.) (more…)

Client Spotlight: Joe McDonald

I still remember the first time I met Joe McDonald in 2011. He was skeptical. He wanted to cycle his first century at 71. We trained hard and we worked to change his eating to something that would actually fuel him, allow him to get leaner and stronger and feel healthy. He lost 35 pounds and has maintained his eating and his new weight to this day.  We created a sustainable change for him by finding the foods that actually make him feel vibrant. He had been eating multiple bagels in the morning, which left him feeling bloated and lethargic. The trick to his transformation was creating an awareness around the feelings he had after eating certain foods. It wasn’t me coaching him to stop eating all the foods he loved, it was was working together to notice what foods really made him feel great. The physical training, no matter how strenuous, is always so much easier when a person feels well. The gut is the key to all health, mental and physical. We are just beginning to understand the power of the gut microbiome and the roles it plays in creating neurotransmitters and other chemical signals that determine our overall health. (more…)

Client Spotlight: Casey Ford

Casey Ford – an OPRF senior heading off to Lafayette Colleg in the fall – wrote this:

“I started working out with G when I was in 5th grade, at about ten years old. I was born with a very rare connective tissue disorder, and the most impactful fact of that disorder on my physical health is my lack of kneecaps. I worked with G up until around early high school. I began walking with a cane because of my disorder, and mentally I struggled with it. I convinced myself it was better to just sit down and do nothing, I accepted the inevitability of my loss of motion. (more…)
