Matt Ladewski uses an EliteFTS™ SS Yoke Bar with Pro Mini Red Resistance Bands attached to a Glute Ham Raise to strengthen his middle/upper back.
Matt uses EliteFTS™ Pro Mini Resistance Bands (Red) hooking them up to the EliteFTS™ Glute Ham Raise and attaching them around the EliteFTS™ SS Yoke Bar for added resistance. He leans against the Glute Ham Raise to take his lower back out of the exercise in order to target the mid/upper back.
From Dave's Training Log about this exercise:
This is not a beginner exercise. This is about working the muscles and not just doing the motion. If you can't feel or know how to contract this will be worthless for you.
