Every single full meet raw bench press WR is about 20+ years old. Even in bench only meets, most weight classes haven't seen a record in many years.
Deadlifts also aren't broken very often. Ed Coan is a big reason for that but even in other weight classes the WRs are pretty well dispersed over time.
Squat WRs on the other hand are almost all new. Literally 1-2 years old only for almost every single one.
