The thoracolumbar fascia is important to core function because it:

• BThe spine's natural curves maintained in a balanced, low-stress position
• CAlways keeping the back completely flat

The 'abdominal brace' differs from the 'abdominal hollowing/draw-in' strategy because bracing:

• AIs used only for stretching
• BOnly activates the transversus abdominis
• CCo-contracts the entire abdominal wall to maximize trunk stiffness
• DRequires holding the breath indefinitely

During a heavy carry or load-holding task, the core functions mainly to:

The 'inner unit' versus 'outer unit' model of the core suggests that effective training should:

The hip flexors are relevant to core programming because:

• AOveractive hip flexors can increase lumbar load and alter pelvic position

Before prescribing a core program, a fitness professional should first:

Reassessing a client's core endurance and movement quality periodically is important because it:

• CProvides objective feedback on progress and guides program adjustments
• DIs only needed once, at the start

When teaching a new core exercise, the most effective demonstration approach is to:

• ADemonstrate the movement, give concise cues, then watch and correct the client's attempt
