The good morning exercise is similar to the Romanian deadlift, or RDL workout, but they are not the same. They are similar in that: Both exercises require a hip hinge to perform Both exercises improve hip mobility Both exercises primarily target the posterior chain muscles Both exercises build core strength and stability However, there are some key differences: The good morning uses a barbell racked across the shoulders and upper back, similar to the back squat, while the RDL demands a mixed or overhand grip and the barbell held in front of the body Good mornings feature a greater range of motion Good mornings place more emphasis on the lower back and glutes, while RDLs are heavier on the hamstrings They’re both excellent exercises, each deserving a place in your lower body workout routine. For tips on when and how to use each, consider working with a certified personal trainer or other qualified fitness professional.
