Barbell Behind the Back Shrug
Description
The behind the back shrug is a trap-building exercise where you hold a barbell behind your body at arm's length and shrug your shoulders straight up. The barbell behind the body shifts emphasis to the lower and middle traps compared to the front shrug, providing a unique stimulus for trap development.
