Pull-Throughs kinda suck. I only do them for a change of pace and because of the limited equipment available.
If all you have is a Power Rack and a Cable Farm, you can't do Good-Mornings all the time so you'll have to hit up the Pull-Throughs every now and then.
Good-Mornings, Back Extensions, 45' Back Extensions, and Glute-Ham Raises are way, way better than Pull-Throughs.
If you work out at a commercial gym, people are going to look at you weird if you train right. Shit that will freak these people out includes but is not limited to: Snatches, Cleans, Squats of all kinds, Bulgarian Split Squats, Overhead Squats, Deadlifts of all kinds, Good-Mornings of all kinds, Squats, Face Pulls, Full-Range Close-Grip Benching, Heavy Dumbbell Side Bends, Shrugs, and many other excellent exercises.
