Stand with feet hip-width apart holding a dumbbell (either in front of your chest or resting across your upper back/shoulders depending on variation). Keep a slight bend in your knees, chest up, and core braced. Initiate the movement by pushing your hips backward while keeping your spine neutral. Lower your torso forward in a controlled hinge until you feel a strong stretch in your hamstrings or your upper body is near parallel to the floor. Pause briefly, then drive your hips forward and squeeze your glutes to return to a standing position. Avoid rounding your back or bending your knees further during the descent.
Log your dumbbell good morning sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
