Stand with a Smith machine bar resting on your upper back and feet hip-width apart. With a slight knee bend, hinge at the hips to lower your torso forward while keeping your back straight and core engaged. Once your torso is roughly parallel to the floor, drive your hips forward to return to standing, focusing on squeezing the glutes and hamstrings throughout.
Log your smith bent knee good morning sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
