1.)  CORE: From an air squat, to a heavy back squat, a power clean, to a shoulder overhead press; one’s core should always be engaged. Many CrossFit athletes feel like they activate their core, but in reality many are activating their core incorrectly or not at all. Engaging your core does NOT mean “sucking in.” It is about abdominal bracing. This involves activating transverse abdominus muscle, keeping the spine in neutral, and making sure the pelvic floor is strong. To active transverse abdominus one needs to draw their spine into neutral and pop their abdominal muscles outward.
