If want to know how to build your glutes fast, the barbell hip thrust has to be your top pick. I like to use high reps, lesser weight for hip thrusts but anywhere from 6-20 reps is where you want to hang out and switch your rep ranges every now and then. A a rule of thumb, the lower the reps the higher the weight, the higher the reps the lesser the weight. But do challenge yourself at either end.
