Cable Forearm Pronation

Muscles worked

Setup

1. Set the cable pulley to elbow height and attach a single D-handle or a short rope.
2. Stand sideways to the cable machine and grasp the handle with your near-side hand in a neutral grip (thumb pointing up).
3. Bend your elbow to 90 degrees and tuck it firmly against your side, keeping your forearm parallel to the floor.
4. Step away from the machine until there is slight tension on the cable while your thumb is still pointing up.

How to do it

1. Exhale as you rotate your forearm inward, turning your palm toward the floor until your thumb points toward your body.
2. Hold the peak contraction for one second, focusing on the squeeze in the top of your forearm near the elbow.
3. Inhale as you slowly rotate your hand back to the starting neutral position over a controlled 2-second tempo.
4. Complete the full set on one arm before switching sides to ensure equal volume.

Form checklist

• Keep the elbow pinned to your ribs to prevent the shoulder from assisting the movement.
• Maintain a strict 90-degree angle at the elbow throughout the entire set.
• Ensure the movement comes solely from forearm rotation rather than wrist flexion or extension.
• Keep your torso upright and stationary; avoid leaning or twisting your body to move the weight.

Pro tips

• Focus on the 'thumb-down' movement; imagine you are pouring water out of a pitcher to maximize pronator activation.
• Use a 'fat grip' attachment or wrap a towel around the handle to increase the diameter and intensify muscle fiber recruitment.

Make it harder

• Implement a 4-second eccentric phase to increase time under tension and stimulate more hypertrophy.
• Hold the handle at the very end (offset grip) to increase the lever arm, making the rotation significantly more difficult.
