Dumbbell Clamshell Side-Plank

Set up in a forearm side plank with your feet stacked and hips lifted off the floor.

Place a dumbbell securely on the thigh of your top leg, holding it lightly with your hand.

Keep your feet together and slowly raise your top knee upward like a clamshell.

Pause briefly at the top while keeping your core braced and hips stable.

Lower your top knee back down in a controlled movement to complete the rep.
