Smith Machine Good Morning 

You're welcome! I'm glad you found it helpful.

I agree that the safest position is on the rear delts, as I'm demonstrating in the video. Placing the bar lower on your shoulders prevents it from rolling up onto your neck. This isn't as critical on the Smith machine since the bar can't move as much, but it definitely matters with a free-weight barbell.

Yes, the smith machine good morning targets the glutes, hamstrings, and lower back.

This exercise primarily works the hamstrings and glutes.

Para glúteo y femoral

@@AlexisG1309 Definitely exercises the glutes. There are better quadricep exercises such as squats
