Hey guys
during any of my plank / push up / Scap shrug work I'm always trying to protract as hard as I can something that has always seemed quite difficult for me to do . If we compare the pics of me here (my current protraction maximum) to the guys at gb they seem to have much more of a roundness to there protraction. Is this something that will come as I progress through the course or is it down to genetics playing there part here . Btw I've just started the thoracic series although am I correct in suggesting this works more on thoracic extension than flexion ?
Your input would be much appreciated as seeing the roundness of these guys here is the kind of form I'm aiming for
