  • Julia Codling

    Personal Trainer

    Growing up, Julia played field hockey and ran track, where she developed her passion for fitness. When she stopped playing sports, she realized how important physical activity had been for her mental health, body image, and overall confidence. To fill this void, Julia began to lift weights and fell in love with the gym. Now, she has turned her passion for fitness into her job by getting her NASM personal training certification, in hopes of helping others also feel healthier, stronger and more confident by focusing on strength and muscle growth.

    Now, she is building a new career as a NASM certified personal trainer with the hopes of inspiring others to feel stronger, healthier, and more confident. She focuses on strength and muscle growth through resistance training, in order to teach her clients to be healthy for life.

Through her love of training and teaching, she finds an immense joy from the learning that happens not only for herself, but for her clients. "A tremendous gift!"

To achieve this, Karie believes strongly in moving and loading your muscles with ease, keeping the mind/body connection strong and learning to foster those creative pathways through all planes of movement. "We are our own wisest master."
