Holding a dumbbell at your side, hinge forward at your hips while keeping your back straight. Extend your arm upward, fully straightening at the elbow and engaging your triceps. Slowly lower the weight back to the starting position, preventing any shoulder movement.
Keep a slight curve in your lower back. Bend from the hips, retracting your shoulders. Maintain close elbows throughout the exercise. Achieve full arm extension at the peak of the movement. Choose a weight enabling 12-15 repetitions while maintaining good form.
