A quick question regarding Naihanchi Shodan

[username18526]

Hi everyone! I am currently following along with Nagamine’s Essence of Okinawan Karate-do and am a little confused regarding the Morote-zuki in Naihanchi Shodan. When performing the augmented side punch, am I supposed to keep the torso straight or twist it to the side? It’s a little hard for me to tell from the pictures. Thanks for any help you guys can give!

The Kata is known as "Tekki Shodan" in Shotokan, and we keep the torso straight, but depending on your upper extremity and chest width proportions, you might catch yourself doing a slight twist as you reach your fist across our torso.
