Strong body parts will always activate first. Your body likes to make things as simple as possible. Making things easy means less caloric output, maintaining homeostasis and conserving energy. However, when your goal is getting huge or as strong as possible that ain’t happening. So, when doing any row exercis it is very common for the biceps, low back, and synergistic muscles to over activate. This leaves your rhomboids, middle traps left in the wind.
So instead of hearing pull your shoulders back first and a number of other sometimes pointless cues, this exercise allows for immediate feedback by mechanoreception. Mechanoreception is just a term for one being able to detect stimulus, touch, sound, pressure change or posture change, via the skin. So, in the below exercise when the band is placed around the shoulders due to its direction it offers a constant feedback to your mechanorecpetors. Your brain senses the pressure and guides you to pull with your retractors first.
This is a great tool to be used in your warm up sets or throughout your working sets if you dont mind looking like a jack ass. Give it a try and let me know what you think!
