The trap-3 raise is used to target your mid-rhomboid muscles. These lay between your shoulder blades and play a key role in stabilizing your shoulder blades. Unfortunately, for many of us, they are asleep! Sitting hunched over at a desk for many hours tends to leave our upper back muscles week and ineffective.
Trap-3 raise allows us to specifically target these key muscles and start to build a powerful, functional upper back!
