Press dumbbells upward and outward to an overhead Y shape. Fully extend arms, pausing briefly at the top. Slowly lower weights back to the starting position.
Engage your core muscles throughout the exercise to maintain stability and prevent lower back strain, which will help transfer power from your legs and torso. Initiate the movement by leading with your elbows, drawing them outward to guide the dumbbells and ensure proper shoulder engagement. Press the dumbbells in your scapular plane – the natural angle of your shoulder blades – to maximize muscle activation and minimize risk of injury. Consciously avoid arching your lower back by maintaining a neutral spine and bracing your abdominal muscles.
