1
Start in a prone position supported on forearms and toes (plank position), with elbows directly under shoulders, body forming a straight line from head to heels, and core engaged
2
Maintain neutral spine alignment and engage abdominal muscles by bracing core, keeping forearms parallel and shoulders stable over elbows
3
Lower hips toward floor by allowing slight spinal flexion while maintaining control, feeling increased abdominal tension through the eccentric movement
4
Return to starting plank position by engaging abdominals to lift hips and bring body back to straight alignment, squeezing core at the top
