For hamstring growth
For hamstring growth, glute-ham raise rates higher on our research criteria: easier on the joints, more of the work on the hamstrings.
Good morning gives more stretch.
Both are good choices, and they train the hamstrings differently. Using both across your week covers more of the muscle than either alone: in studies, varied exercises grew parts of a muscle that one exercise missed. (Fonseca et al., 2014; Costa et al., 2021)
The research score comes from these, scored by hand from the studies. Lifter scores appear once an exercise has 10 ratings. How scores work
Glute-Ham Raise. Trains the hamstrings at the knee and hip together, but bodyweight is a lot to start with and hard to add to.
Good Morning. A big hamstring stretch, but the bar on your back makes it demanding on the lower back.

About the same: both take some practice.
Glute-ham raise needs a GHD or back-extension bench, so for most people it’s a gym exercise. Good morning needs a barbell and a squat rack, so for most people it’s a gym exercise.
Glute-ham raise: it rates Strong for joint and recovery cost in our research rubric, against Fair for good morning.
