I read a good article recently over on T-Nation by Tony Gentilcore:
Strong Traps, Healthy Shoulders
Your trapezius muscle, aka the traps, is a large muscle in your upper back/neck area. A lot of people will train it with upright pulling motions and shrugs, but Tony Gentilcore breaks down a lot of ways to strengthen the entire muscle more effectively.
This features some very effective and useful lifts:
- the landmine press (especially for people with shoulder issues)
- the vertical Pallof Press
- overhead shrugs (something I first encountered maybe 20 years back, and it's still underutilized)
- a variant of the Y using suspension trainers
It's a good article and very useful if you have either an over-active trap or under-active and need to get it all firing and working correctly.
