Reverse Fly Machine

How to do it

Sit facing the pec deck machine's back pad and grip the handles positioned in front of you at chest height.
Press your chest against the pad and set your feet flat on the floor for a stable base.
Brace your core, then pull both handles back and apart in an arc until your arms are extended out to the sides.
Squeeze the posterior deltoid and upper back at the end of the movement before slowly returning the handles to the front.
Keep a controlled tempo through both directions, exhaling as you pull back and inhaling as you return.
Keep your chest pressed into the pad rather than arching your back to pull the handles farther.
