SLow its not that those lifts are boring, its that those require the most energy to complete. Your gonna tell me people want to bust ass in the gym for results? HAHAHA say it aint so!

All lifts eventually get "boring". There is only so much you can do before you repeat. It stops getting boring when the mirror rewards you.
There are weeks where I get bored with certain body parts, sometimes months. The mirror helps me snap out of it
