Julie Edstrom

Julie founded Edstrom Fitness in 2014 and since then has been primarily focused on helping others achieve overall health and wellness. She began bodybuilding at the age of 15 and dreamed of teaching others a healthier way of life. Julie is also a natural figure competitor and enjoys the challenge and process of doing what it takes to compete.

After having two children and having to fight back from an excessive pregnancy weight gain, she swore she would never be unhealthy again. She decided to make it her mission to teach others how to make lifestyle changes and be healthy.

Julie has an amazing husband, Brandon, and two daughters, Celine and Alexis, who also live a healthy lifestyle. They all exercise, have good eating habits, and work out regularly.
