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.

  • Joe Robbins

He began lifting at the age of 17 and quickly became hooked. He focused on learning compound movements and working on isolation movements, whilst focusing on progressive overload. Hitting a plateau with physique goals, his gaze shifted to building strength. He spent the next few years engaging with numerous strength programming approaches. After struggling with a celiac disease diagnosis in 2020, he was determined to prove this would not take away his ability to continue strength training and so focused on educating himself about autoimmune disease and nutrition. Joe is now a competitive powerlifter and firm believer in the long term physical and mental health benefits strength training can provide. His personal journey with celiac disease has made him a compassionate and knowledgeable teacher. His training philosophy focuses on barbell movements with an emphasis on proper technique, effective programming, consistency, and recovery, with the aim of achieving long-term success.
