Quadruped Abdominal Draw-In
Abs


Core / Advanced / Compound (multi-joint)
From kneeling, roll a loaded barbell forward and back to train the abs in anti-extension.
Loads the lower back, shoulder. Use a load you can control and skip it if it causes pain.
Why it hurts: The lower back is pulled into hyper-extension under body weight, a common strain.
✓ Instead: Roll only as far as you can keep a posterior pelvic tilt (slightly tucked tailbone). Roll toward a wall to limit the range.
