How to do the standing inner-biceps curl
- Stand up with a dumbbell in each hand being held at arms length. The elbows should be close to the torso. Your legs should be at about shoulder's width apart from each other.
- Rotate the palms of the hands so that they are facing inward in a neutral position. This will be your starting position.
- While holding the upper arms stationary, curl the weights out while contracting the biceps as you breathe out. Your wrist should turn so that when the weights are fully elevated you have supinated grip (palms facing up).
- Only the forearms should move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Tip: Keep the forearms aligned with your outer deltoids.
- Hold the contracted position for a second as you squeeze the biceps.
- Slowly begin to bring the dumbbells back to the starting position as your breathe in. Remember to rotate the wrists as you lower the weight in order to switch back to a neutral grip.
- Repeat for the recommended amount of repetitions.
Muscles worked
The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.

How this movement works
One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
Dumbbells let each side work on its own, surfacing a strength difference between limbs that a barbell would quietly cover for, and leaving the wrist free to rotate through the movement.

Difficulty
Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
