Resistance-Band Clamshell Side-Plank

Lie on your side with your forearm resting on the floor directly beneath your shoulder and your knees bent at a 90-degree angle.

Lift your hips off the ground to form a straight line from your head to your knees while keeping your feet stacked together.

Engage your core and glutes to maintain a stable side plank position throughout the movement.

Keeping your feet pressed together, slowly open your top knee upward like a clamshell.

Pause briefly at the top, then lower your knee back down in a controlled manner.
