The barbell standing reverse grip curl is one of the most direct paths to building thick, functional forearms that improve every pulling movement you do. Flipping your grip challenges the wrist extensors and brachioradialis in a way standard curls simply cannot replicate.
Stand tall with feet hip-width apart, grip the barbell overhand with hands shoulder-width apart, and let it hang at full arm extension
Brace your core, pin your elbows to your sides, and curl the bar upward by driving your knuckles toward the ceiling
Squeeze the forearms hard at the top without letting your elbows drift forward or your wrists collapse downward
Lower the bar under full control back to the start position over a 2 to 3 second count
Common mistakes
Letting the wrists buckle downward under load, which shifts stress off the target muscles — actively keep the wrists neutral or slightly extended throughout the entire rep
Swinging the torso to generate momentum — reduce the weight and initiate every rep from a dead stop with the upper arms locked
Cutting the range of motion short at the bottom — always return to full elbow extension so the brachioradialis gets a complete stretch before each rep
Pro tip — Pause for a full second at the top of each rep with your wrists held flat and firm — this isometric hold exposes and eliminates the wrist instability that leaks tension away from the forearms.
