Using reverse engineering and fundamental principles, Wiebe describes programming around the big seven movements, progressive overload, and objective and subjective feedback. She reflects on her path through Kenya, Dubai, and the Dominican Republic, gaining exposure to athletes across sports, backgrounds, and abilities. Logistical challenges, like language barriers and limited resources, strengthened her adaptability and creativity. Wiebe believes weight room culture starts the moment you walk in.
