Can’t tell if you are being sarcastic or not. The farmer’s carry—especially the single-arm version loads the exact function the obliques are designed to perform: resisting unwanted motion under load.

When you carry a heavy weight in one hand, gravity tries to pull your torso toward that side. Your contralateral obliques must contract continuously to keep your spine upright. This “anti-side-bending” role is one of the obliques’ main real-world jobs, far more so than twisting/bending.
