Isolateral Incline Pec Fly

The Isolateral Incline Pec Fly is an advanced upper-body isolation exercise that targets the upper chest (clavicular head of the pectoralis major) while promoting unilateral movement for improved muscle activation and balance. Unlike traditional incline fly machines or dumbbell variations, the isolateral design allows each arm to move independently—enhancing range of motion, correcting strength imbalances, and reducing joint stress.

This exercise is typically performed using cable systems with independent handles , dumbbells on an incline bench , or specialized isolateral machines , making it ideal for both hypertrophy and functional performance training.
