Start in a push‑up position with both hands gripping dumbbells and your shins or feet supported on a stability ball. Engage your core to keep your body in a straight line from head to heels. Row one dumbbell toward your hip by bending your elbow and pulling your hand up while keeping hips square to the ground. Lower the dumbbell with control, then immediately row the opposite side. Maintain a stable torso throughout—avoid twisting or rocking your hips as you alternate rows.
