What are the best things to do to harden my ass?

Hi there.

best exercise i found to harder my bottom was barbell glute bridge.. i do this with about 40 kg.. its insane. i promise you, you will feel it. i do it on a bench, with my upper body on the bench and my legs under. put barbel over pelvis aream (use handoek).. and lift and hold for few secs.
