1
Start in a plank position with hands shoulder-width apart, arms fully extended, body in a straight line from head to heels, core engaged, and feet hip-width apart
2
Ensure neutral spine alignment, shoulders directly over wrists, and engage abdominal muscles to maintain rigid torso positioning throughout the movement
3
Bend one knee, drawing the foot toward the chest in a controlled manner while maintaining plank position with the other leg extended, allowing the quadriceps of the working leg to lengthen
4
Extend the bent leg back to starting plank position, driving through the quadriceps to powerfully straighten the leg, then alternate sides in a dynamic alternating pattern
