How to Perform
- Stand with dumbbells at your sides, palms facing your body (neutral grip)
- Keep your elbows pinned to your sides
- Curl the weights up while keeping your palms facing each other throughout
- Squeeze at the top for 1 second
- Lower with control over 2-3 seconds
Tips
- Keep palms facing each other the entire time — rotating your wrists turns it into a standard curl and changes the target muscles
- No dumbbells? A rope attachment on a low cable in a hammer grip works perfectly
- Use a 2 second curl and 3 second descent — the brachialis responds especially well to slow negatives
- Swinging the dumbbells and flaring your elbows forward is the most common mistake — keep your upper arms completely still
- Feel the contraction on the outside of your upper arm (brachialis) and the top of your forearm (brachioradialis), not just the bicep peak
