How to do the one arm supinated dumbbell triceps extension
- Lie flat on a bench while holding a dumbbell at arms length. Your arm should be perpendicular to your body. The palm of your hand should be facing towards your face as a supinated grip is required to perform this exercise.
- Place your non lifting hand on your bicep for support.
- Slowly begin to lower the dumbbell down as you breathe in.
- Then, begin lifting the dumbbell upward as you contract the triceps. Remember to breathe out during the concentric (lifting part of the exercise).
- Repeat until you have performed your set repetitions.
- Switch arms and repeat the movement.
- Switch arms again and repeat the movement.
Muscles worked
The prime mover is the triceps brachii, which straightens the elbow, and through its long head helps pull the arm back at the shoulder.

How this movement works
One joint moves, and it moves the load away from the body. With nothing recruited to assist, the target muscle reaches its own limit rather than the limit of the weakest link in a chain — which makes this useful for adding volume after the heavy compound work, not for opening a session.
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.
