⚠️ Most common mistake: Pulling with the arms or shoulders instead of curling with the abs, which removes the load from the target muscle. Using a heavy stack and a tiny range of motion, which trains momentum rather than the abs. Letting the weight stack snap back at the top, killing the slow lowering where most growth tension lives. Setting the chest pad too high on the throat, which makes the lifter brace with the neck instead of the core.

💪 Where you should feel it: Mainly in the Keskivartalo.
