How to do the lying supine dumbbell curl
- Lie down on a flat bench face up while holding a dumbbell in each arm on top of your thighs.
- Bring the dumbbells to the sides with the arms extended and the palms of the hands facing your thighs (neutral grip).
- While keeping the arms close to your torso and elbows in, slowly lower your arms (as you keep them extended with a slight bend at the elbows) as far down towards the floor as you can go. Once you cannot go down any further, lock your upper arms in that position and that will be your starting position.
- As you breathe out, slowly begin to curl the weights up as you simultaneously rotate your wrists so that the palms of the hands face up. Continue curling the weight until your biceps are fully contracted and squeeze hard at the top position for a second. Tip: Only the forearms should move. Upper arms should remain stationary and elbows should stay in throughout the movement.
- Return back to the starting position very slowly.
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.

Listed at beginner level: the pattern is simple enough to pick up without coaching, and a position that goes wrong mid-set is obvious enough to correct on the next repetition.
