1
Start in a side plank position with your right forearm on the ground, elbow directly under your shoulder, body in a straight line from head to feet, and your left leg stacked on top of your right leg or with feet staggered for stability.
2
Engage your core and ensure your hips are lifted high, creating a straight diagonal line through your body. Place your left hand behind your head or across your chest.
3
Lower your left hip toward the ground by rotating your torso laterally, allowing a slight dip but maintaining proper alignment. This is the eccentric phase where obliques lengthen under tension.
4
Drive your hips back up by contracting your obliques and lateral core muscles, returning to the starting side plank position. Squeeze at the top to complete the concentric phase, then repeat for prescribed reps before switching sides.
