How to do the Resistance Band Chest Fly

Stand with the band anchored behind you at chest height, stepping forward to feel its pull.
Stand in a staggered stance with a slight knee bend and a straight back.
Pull your arms inward, like you’re hugging a large ball in front of you.
Slowly return to the starting position, feeling a stretch in your chest.

Full technique — 7 steps

Anchor the band behind you at chest height and step forward until tension is present with arms opened wide.
Stand in a split or staggered stance with a slight knee bend and torso upright.
Start with hands slightly outside shoulder line, palms facing inward, and a slight bend in your elbows.
Draw your arms inward in a wide arc until your hands meet in front of your chest.
Keep the elbow angle nearly unchanged as the chest drives the movement, not the hands.
Squeeze briefly at the fully shortened position without letting shoulders roll forward.
Return along the same arc until the chest is stretched and the band pulls your arms open.
