What It Works

The dumbbell bicep curl trains the front of the upper arm — the muscle you use to bend the elbow. It also challenges the forearm as you hold the handles.

In everyday life this is the same pattern as lifting a grocery bag, picking up a child, or carrying a laundry basket by bending the elbows.

How to Perform

Stand tall with a dumbbell in each hand at your sides, palms facing forward. Soften the knees and brace your core. Keep the elbows close to your ribs.

Bend the elbows and curl the weights toward the shoulders without swinging. Squeeze at the top. Lower under control until the arms are long again. Don’t let the elbows drift forward.

Setup & Movement – Quick Bullets

• Stand tall, elbows close to the ribs
• Curl the weights toward the shoulders
• No swing of the torso
• Squeeze at the top
• Lower under control
• Elbows stay put

Common Mistakes

The most common issues are swinging the weights, letting the elbows drift forward, rushing the lower, and leaning back to finish the curl.

Watch Out For

• Swinging or leaning back
• Elbows drifting forward
• Dropping the weights quickly
• Shrugging the shoulders

Quick Fixes

• Pin the elbows to the sides
• Think “only the forearms move”
• Own the lowering phase
• Use a weight you can curl without swaying

Key Cue

Elbows still. No swing.

If the torso has to help, the weight is too heavy. Slow it down and keep the elbows parked.

Scaling

Easier: Use lighter dumbbells or curl one arm at a time.

Harder: Slow the lowering phase or add a pause at the top.
