From Humble Beginnings to Global Recognition
Joleen’s journey into fitness began in her hometown of Victoria, British Columbia, where she started her career by working at the front desk of a small gym while studying her NASM textbooks in her spare time. It was there, in the quiet moments between classes, that Joleen’s passion for training blossomed. After completing her education in Vancouver, she returned to Victoria, where she opened a small group fitness class for college women.
Her goal was simple: to create a space where women could focus on building strength through functional fitness, something she believed was often overlooked in traditional gym settings. She recognized that women have different fitness needs than men, requiring specialized programs to achieve their athletic goals, and that the equipment provided in most gyms was designed for male bodies. By teaching college women the three foundational lifts , hip thrusts, deadlifts, and Bulgarian split squats, Joleen not only helped them build a strong, athletic lower body but also made sure they trained with equipment suited to their needs. Her focus was always on functionality over aesthetics, with aesthetic results naturally following from her performance-based programming.
