Are shrugs necessary for big traps?

In order to grow your traps they need HEAVY WEIGHT and VOLUME, but performing only shrugs isn’t going to cut it. Traps are not like other muscle groups. They need PUNISHMENT and can handle a lot of it! The problem with shrugs and similar exercises is that they’re not challenging enough.

What can I do instead of shrugs?

Do the Face Pull To really get the most out of it, have the cable pulley set at eye-level or a bit higher so the movement is slightly downwards which will further minimize upper trap involvement. Exaggerate the movement of the scapulas on the stretch and hold each peak contraction for 3-5 seconds.
