Mario has just completed an intense core training workout. If he did this workout with correct form, where might he MOST logically feel sore from this workout?

in his legs

in his abdomen

in his arms

in his neck

Mario would most logically feel sore in his abdomen from the core training workout, as it is specifically targeting the muscles in the core, such as the rectus abdominis, obliques, and transverse abdominis.
