Lift shoulders, engage core. Extend left leg, draw right knee in. Twist torso, bringing left elbow to right knee. Switch sides, extending right leg and drawing left knee in, rotating right elbow to left knee. Alternate sides continuously, maintaining band tension and low back contact.
Press your lower back firmly into the floor to stabilize your core and prevent arching. Initiate the twisting motion from your torso, avoiding any neck rotation to protect your spine and focus on oblique engagement. Keep your elbows wide throughout the exercise to maximize oblique activation and prevent shoulder strain. Ensure your shins remain parallel in the tabletop position to maintain balance and proper spinal alignment. Actively engage your obliques during the twisting phase to deepen the contraction and improve rotational strength.
