How do you train clients with over-active upper traps (who initiate movements w a shoulder shrug)?
Before any pulling exercise they should pull the shoulders back and down. Each rep should be done with this thought in mind. Chest up, shoulders down and back, core tight, navel into spine… Bodyweight exercises, such as pull-ups, assisted pull-ups, or body pulls / trx rows are great for this.
Weak lats and rhomboids lead to overcompensation with biceps and traps.
