About Us

Throughout our lives, we have had a passion for exercise and the science that supports it. This dedication has given us the means to take the knowledge and experience that we’ve gained and help people form good habits to improve their lives.

Over the past 10 years, the health and fitness industry has been redefined. As personal trainers in Chicago, we realized the importance of incorporating these most recent innovations into our style and system of training.

Our goal in creating G.I. Jane Fitness, has been to bridge the gap between the work of doctors, physical therapists and nutritionists with the skills and knowledge of a qualified exercise specialist. It is this collaboration that allows us to offer an unprecedented level of service with professionalism, consistency and distinction.

G.I. Jane

Jane FolzJane began her fitness career at 13 years of age, when she realized the  benefits of exercise and proper nutrition.

While most teenagers spent time in the malls, Jane spent her time exercising. Jane, a mother of four, has always kept herself fit through exercise. She is a graduate of the Fitness Instructor Training program at McHenry County College and is certified through the American College of Sports Medicine. Jane also holds a degree as a Cancer Exercise Specialist. Jane and her five children live in Northern Illinois and spend their free time exercising, camping, boating, biking, running, good old fashioned playing and enjoying family time together.

Jane believes that to successfully progress through the trials of life, one must challenge their mind, body, and soul to secure a feeling of wellness. Jane’s goal is to get and keep people motivated to make deliberate lifestyle changes relative to their personal responsibilities for optimal enhancement of physical, mental, and spiritual health, equaling complete wellness. Jane’s training method is generally functional. Functional training is fun and will enhance your ability to perform everyday life activities better. Jane gives no ordinary workout.

Tino Rivera

I am an NSCA Certified Personal Trainer with a passion for all around fitness. I enjoy witnessing and being a part of micro and macro goals set by each individual that I have the privilege to train. Being that I was once obese, I have the sympathy and empathy for those who suffer from this very same issue. I also enjoy sports and have been involved in some kind of sport throughout my life. Specificity is essential for improving ones gains especially for athletes.

I enjoy training those who are rehabilitating due to an injury. My coming from a holistic preventative Chiropractic clinic has allowed for me to gain insight and knowledge on how to effectively train individuals who suffer from an injury or recovering due to surgery. I have a beautiful wife and two precious daughters. I have my degree in Health and Fitness Education and am currently completing my degree in Health and Human Sciences. My passion for fitness has lead me to continue my education both academically and professionally
