Jen Poljacik

Cardio Boot Camp Instructor

​Jen started her career teaching group exercise and never stopped because she believes in community, connection, and how beneficial exercise can be emotionally.


She has dedicated her professional career to helping others live better and believes health and wellness are to be shared with one another. The results we see by prioritizing our own health will become contagious and affect others around us. Her philosophy is, “We can create a better way of life,” one person at a time. She is passionate about all aspects of wellness and especially creating a good healthy environment and good habits at home to be shared with our younger generation so they may also enjoy a better life.


No matter where you are starting your wellness journey, she is passionate and committed to inspiring you to create a positive change in your own life and create new healthy long-term habits that can be passed along. My enthusiasm, dedication, and motivation are contagious, and I refuse to fail at helping people get what they want most.
