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.
