Good Morning’s are a compound exercise that primarily target muscles in the rear chain (backside of the body), but especially the hamstrings, and lower back. While this can be an effective exercise, there is some risk to performing this exercise with a loaded barbell on your back. If you’re unfamiliar with this exercise, try starting with a dumbbell variation as you learn the movement.
Barbell good mornings are named for their resemblance to the motion of bowing or bending forward to greet someone in the morning. The exercise involves bending at the hips with a barbell on your shoulders, similar to the way one might bow when saying "good morning."
Standing good mornings primarily work the hamstrings, glutes, and lower back muscles (erector spinae). They also engage the core muscles for stabilization and the upper back and shoulders to maintain proper posture during the movement.
Rounding your back will allow you to reach closer to the floor, but also increases your risk of injury, and reduces the effectiveness of this exercise. Focus on keeping your shoulders back, and your lower back braced to support your spine. Hamstring flexibility is the deciding factor in how low you can go.
