Equipment


Form Cues
-
Sit on a flat bench positioned in front of the Smith machine bar.
-
Rest your forearms on your thighs with your wrists hanging over your knees, palms facing up (supinated).
-
Grip the Smith machine bar with an underhand grip, roughly shoulder-width.
-
Let the bar lower by extending the wrists, getting a full stretch in the forearm flexors.
-
Curl the bar upward by flexing the wrists, squeezing at the top.
-
Keep your forearms firmly pressed against your thighs — only the wrists should move.
-
The Smith machine's fixed path keeps the bar stable, allowing you to focus purely on wrist flexion.
-
Use a controlled tempo and moderate weight — wrists are vulnerable to overloading.
