How to do the one-arm flat bench dumbbell flye
- Lie down on a flat bench with a dumbbell in one hand resting on top of your thigh. The palm of your hand with the dumbbell in it should be at a neutral grip.
- By using your thighs to help you get the dumbbell up, clean the dumbbell so that you can hold it in front of you with your lifting arm being fully extended. Remember to maintain a neutral grip with this exercise. Your non lifting hand should be to the side holding the flat bench for better support. This will be your starting position.
- Your arm with the weight should have a slight bend on your elbow in order to prevent stress at the biceps tendon. Begin by lowering your arm with the weight in it out in a wide arc until you feel a stretch on your chest. Breathe in as you perform this portion of the movement. Tip: Keep in mind that throughout the movement, your lifting arm should remain stationary; the movement should only occur at the shoulder joint.
- Return your lifting arm back to the starting position as you squeeze your chest muscles and breathe out. Tip: Make sure to use the same arc of motion used to lower the weights.
- Hold for a second at the contracted position and repeat the movement for the prescribed amount of repetitions.
- Switch arms and repeat the exercise.
Muscles worked
The prime mover is the pectoralis major, which drives the upper arm forward and across the body.

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.

Difficulty
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.
