TRX Y-Fly

How to do it

Grip the TRX handles overhead and lean back from the anchor with arms extended, body forming a straight line from head to heels.
Set the feet shoulder-width apart and brace the core to keep the torso rigid through the movement.
Pull the handles up and outward at a diagonal until the arms form a Y overhead, thumbs rotating up and back.
Keep the arms straighter than in the T or W fly, since the Y pattern works through a longer lever with lighter resistance.
Exhale as the arms reach the Y position, then inhale while slowly lowering back to the starting lean.
Keep the ribs down and avoid arching the lower back to reach the Y position.
