Pec Deck Fly

ChestPec Deck Machine

An isolation exercise focused on targeted chest work without involving your triceps. Great for building strong muscle activation during the squeeze.

How to do it

1Adjust the seat so the handles or pads sit at chest level.

2Press your back into the pad, pull your shoulder blades together, and plant your feet on the floor.

3Bring your arms together in front of you, driving through your elbows using chest strength.

4Control the return to the starting position without letting your shoulders collapse back.

Common mistakes

Opening your arms too far back past your torso, overstressing the shoulder joints.

Bending and extending your elbows during the rep, shifting work from your chest to your arms.

Rounding your back as you bring your hands together, disengaging the target muscles.

Breathing

Inhale as you open your arms out to the sides; exhale as you bring them together in front.

Make it harder or easier

Drop the weight and shorten the stretch range to make it easier.

Hold the handles together for a two-second squeeze at the peak contraction to step up the intensity.

This is general guidance, not a medical opinion. Listen to your body: if it hurts, stop. If you have an injury or a chronic condition, talk to a doctor first.
