An isolation exercise for the chest muscles performed with arms in a wide arc motion, bringing weights from an extended position to meet over the chest. Can be done with dumbbells, cables, or on a machine.
From 'chest' (the target muscle group) + 'fly' (the wing-like motion of the arms). The name evokes the motion of a bird's wings, reflecting the exercise's distinctive arc-like movement pattern.
The chest fly provides a unique stretch-and-squeeze stimulus that pressing movements can't replicate - it's one of the few exercises that targets the chest through its full range of motion! The deep stretch at the bottom position is crucial for muscle fiber development and flexibility.
