Start in a prone plank position with forearms on the ground, elbows directly under shoulders, body forming a straight line from head to heels, core engaged and neutral spine maintained
2
Maintain rigid plank position with forearms anchored, engage core muscles, keep glutes tight, and prepare to lift one leg while maintaining hip level stability
3
Slowly lower the extended leg back toward the starting position in a controlled manner, maintaining plank alignment and preventing hip rotation or sagging
