The machine chest fly is a machine-based exercise targeting the chest. It approximates the motion of a dumbbell fly or cable fly, but is usually performed facing forward and seated upright. The motion is often compared to bear-hugging a tree trunk. The chest fly is usually performed for moderate to high reps, such as 8-12 reps per set or more, as part of a pre-exhaust or muscle-building upper-body workout.
