3–4 sets × 12–15 reps (50–70% 1RM, RPE 6–7)
3–4 sets × 10–12 reps (60–75% 1RM, RPE 6–8)
2–3 sets × 15–20 reps (30–50% 1RM, RPE 5–7)
Maintain a fixed, slight bend in your elbows throughout the movement
Bring the handles together in a smooth arc above your lower chest
Squeeze your lower chest hard at the top for 1-2 seconds
Control the descent slowly, taking 2-3 seconds for maximum stretch
Keep your back firmly against the decline bench
Focus on using your chest muscles, not your arms
Bending your elbows too much - turns it into a press instead of a fly

Bending your elbows too much - turns it into a press instead of a fly
Straightening your arms completely - can strain your elbows
Not bringing the handles together at the top - incomplete range of motion
Moving too quickly - loses the benefit of constant tension
Arching your lower back off the bench - can strain your back
Using too much weight and losing the stretch - defeats the purpose

The cable chest fly is an isolation exercise that targets the pectoralis major with continuous tension. Unlike presses, the fly emphasizes shoulder horizontal adduction and a deep stretch-to-squeeze arc, making it excellent for chest shape, mind-muscle connection, and hypertrophy.
The decline dumbbell fly is an isolation exercise that targets the lower portion of the pectoralis major. The decline angle emphasizes the lower chest fibers.
The cable crossover is an isolation exercise that targets the middle and lower chest with constant cable tension. This exercise provides a unique squeezing contraction, making it excellent for chest definition and mind-muscle connection.
The machine pec deck fly is an isolation exercise that targets the pectoralis major with a fixed movement path. This exercise provides constant tension and eliminates stabilizer involvement, making it excellent for chest mass and definition.
